Well, TJ asked if I had a build thread, so I thought I might as well make one. A few other members have also shown an interest in the ski, so here it is.

I am over on PWCforums.co.uk also, but no thread there. PNG is the place for non-Nova threads, and now it seems, non-car. lol

OK, a little background first (nautical puns to be expected). I have wanted a ski for ages, years so finally took the plunge on this 2001 GPR, after reading up a little on them, as my knoweldge of them didn't extend past renting one abroad.

I went for an N/A 2 stroke, as they are more reliable, and although you hear they are heavier on fuel than a 4 stroke, I disagree.

The 120 hp 800cc motor in mine is a very good compromise between power and economy.

A 60L tank of unleaded and Yamalube 2 stroke PWC oil will last all day (a long time in jet ski's!)

So this one came up locally, very locally infact. It was only 4 miles up the road. I broke the most vital rule in the book when buying though, I didn't do a water test!

Luckily, it was fine. Had I bought a Seadoo then it could well have been a different story, lol

The GPR is exactly what I wanted. A race winning hull design that just loves wave jumping and dicking about, and is very agile.

I paid £1500 for it, and it came with receipts for a full engine rebuild from Jet Shed only around 10 hours ago. The rebuild alone totalled over £1900. It still had around 1/4 of
a tank to burn before it was fully run in.

It had also recently been painted white and had no real graphics to speak of. This was a shame, but wasn't gonna stop me. It also runs premix, that is to say the sometimes troublesome oil injection
has been disabled.

I was told if you pay that kinda money for a ski, then it's highly likely you get burned - luckily I escaped!

As I bought it

First time out, I ran into some other locals on a Waveraider, one got a backer from me down the river and out into the sea along to the beach.

Bearing in mind I wasn't meant to give it full throttle until run in, it was bloody quick! The
'dreamometer' reads in KPH, and was showing 110 in next to no time, two up with a only quick WOT burst after accelerating from half throttle.

They are meant to do just over 60 mph when new, and I reckon this one is right on the money still, maybe even a little quicker.

Right, we follow the Waveriader to the beach where he beaches his ski to empty water out of the hull (exhaust had a hole in it) so I beach mine too, and assist.

When sorted, I offer the lad a shot on mine. He hops on, I start pushing it out and he barks it up, sucking a load of stones straight into the jet pump in the process.
I was about to tell him the water was still too shallow! :/

The engine cut out immediately and was jammed when hitting the starter.

Jetski's don't like stones!

So here we are, me with my new toy, on holding it on it's side whilst it lies in all the stones on the 'beach' with the tide lashing in, scratching the sh!t out of it whilst I let some random who seems to have half an idea what to do strip part of my jet pump apart to eventually free a 3x1" stone!

Thankfully, after the surgery, aside from the new battle scars, it seemed fine afterwards at least, and I had a riot in the sea!

Were it not for the tidal slipway/rocks everywhere I would have asked for a tow and recovered it on the trailer to inspect later.

Was gutted about the gravel rash right down the side, but hey ho!

So a few more outings come and go, but my smile doesn't!

Until after airshow day (I got stuck in the river Wear at its lowest that day, 1') lol

I decide to trailer it down to my mates in Somerset whilst I am on holiday, we take it to Middlemoor watersports lake. Some 20 acre manmade thing. It wasn't great tbh.

It is there though that the ski developed a cavitation problem, it feels like a slipping clutch, and as you can imagine, severely affects the acceleration, but thankfully not so much the top end speed. So we used it there, after being told by the lake owner that it is the wear ring in the pump,
and it won't wreck anything else.

Two days later we took it to Exmouth beach.

That was a great day! The lack of instant acceleration was mostly made up for by jumping large boats wakes and playing with other skis.

When I got back home I stripped out the jet pump, and found what I was expecting

http://img.photobucket.com/albums/v698/ManorQuay/Random/20120728_154950.jpg
http://img.photobucket.com/albums/v698/ManorQuay/Random/20120728_154754.jpg

A dented impeller and worn wear ring - cheers stones!

What I didn't expect was that my impeller was a Solas Concord, and it also had a PPK pump stuff kit fitted, Riva Yamaha trim tabs, pump shoe, ride plate, intake grate etc - very worthy mods for speed, handling, reducing cavitation and cost coming on £1000 on their own. :)

I sent my pump assembly to Jet Shed in Yorkshire to have the impeller repitched, bearings replaced, wear ring replaced, and the whole thing balanced.

Upon its return I refitted it and then a few weeks later (as I lost a trim linkage piece so couldn't attach the nozzle to the jet pump) I took it for a blast at my newly joined marina, Hartlepool.

A mate who has rented skis on holiday before came along. I took it out to warm it up, and played about for around 10 minutes - it was awesome! Instant hook up and far superior acceleration than it had when I first bought it.

£300 well spent imo. Others may disagree lol.

So my mate jumps on, is out about 10 mins, then radios me (luckily I had just bought some submersible UHF's for marina/emergency communication).

He tells me it's stopped dead.

I assumed it could have been the battery. One of the terminals has bounced loose before, but nope.

He was towed in by a friendly RIB, and upon arrival, I hit the start button and could hear the starter spinning freely, not good!

After speaking to a mate from PWC forums (he also once overed my ski ater purchase, compression test etc - stuff I should have done and said I got a helluva deal, and he's a stand up man. So pleased with that.)

I had the mission of removing 'the front cover' to get at and assess the starter.

Many hours later, I had the exhaust and starter off, and then front cover.

This involved removing allsorts. Nothing like I had ever planned getting into when I bought it.

They are pricey for parts, and even worse if you don't roll your sleeves up though, so I am more than game to save some money and expand my knowledge on the thing!

The front cover is also the front engine mounts, and they are shimmed. It was all getting a bit scary tbh. As the shims on the mounts balance the engine with the prop. So they are critical.

Inspecting flywheel/starter/stator (the copper wound thing, basically the alternator)

As you can see, there is no room at all. The flywheel end of the engine faces the front of the ski, and there is no room to get your head in.

The starter looked OK (sounded grumbly though), the stator is toast though. Something has been bouncing about in there, but what?

Turns out to be part of this! I recovered the small pieces, and if further proff was needed, you can see where they originated.
http://www.lineonedist.co.uk/pics/products/fullsize/Aqua%20Torque%20Bendix.jpg

The Bendix/starter reduction gear. Does what it says, and bridges the gap between the starter and flywheel.
I could feel it was knackered once I removed the front cover. So much slop it was unreal.

It's only meant to turn one way.

To unplug the stator I had to actually, factually remove a million and one bolts from the electric box. I reckon it's pretty waterproof!

http://img.photobucket.com/albums/v698/ManorQuay/20120901_234959.jpg

So I let it at that, and took it to Dodgers the next day, when I found out what had gone wrong.

The Bendix contains two centrifugal clutches, and due to water getting in the front cover (thanks to it being poorly sealed by a previous owner - you didn't need the sealant - the rubber gasket is there for a reason!) the oil on the Bendix had been washed off and it came to bits, then was very nicely fired at the stator by the magneto/flywheel. Hence it dying on the water.

I do wonder if it was the same guy that sent the engine off for rebuild. As I can't see why else the stator would need to be removed normally.

Cheers! lol

Incidentally, starters, stators and bendix units do break, so it's better in a way that I am replacing all of these in one go. My ski will now be in tip top condition. :)

Coming from a car background, I thought nothing of the rust on this mild steel part

http://img.photobucket.com/albums/v698/ManorQuay/20120901_225854.jpg

but it transpires that it shouldn't be like that, hence people knowing water got inside the case. All makes sense when explained!

So Dodger and I decide to remove the flywheel to be able to access/remove the Bendix. What a **** it was. Held on so tight it was unreal.

I now reckon this was cos the Bendix had stayed engaged with the flywheel and heated it right up. Reckon?

http://img.photobucket.com/albums/v698/ManorQuay/20120902_153044.jpg
lol
Still couldn't remove the flywheel at this stage. So we removed a few more parts...

http://img.photobucket.com/albums/v698/ManorQuay/20120902_160911.jpg
Finally it was in the right position to come off.

It was at this point that I decided to just pull the engine out and go ahead with a full respray. I was initially just going to have the top deck (above waterline) repainted.

We inspected the engine, bores were superb. Brand new as claimed. Powevalves were great, and it's only down 3 psi on one cylinder. Has dropped a PV in the past (commong fault) had
waveater clips installed on rebuild so it can't happen again,

Very pleased with the engine itself.

I made a list, and ordered some parts. Starter rebuild kit, new bendix, new stator, new inner exhaust hose - split mine removing exhaust, and a few cosmetic odds and ends, stern drain plugs, new fuel and oil caps, few seals etc, stuff I wanted to have painted and stuff that had white overspray on.

I stripped it down

It's a good read :thumb: I would always be wary about pulling away unless it's in the water but overall it's a top motor and seems like a great purchase after you get the bits sorted

Cheers Brian. It's a great ski, and as you say, sort the stator and bendix out, then everything else is like new. It needs 3' of water to run properly. TBF to matey who sucked up the stones, I was pushing it from the side, and was up to my chest, so he assumed it was OK to go. Must have forgotten/not realised it is 10' long, and the jet nozzle was still in the sand!

Notepad really annoyed me there, it ruined all of my links and sentences. I couldn't leave it lol, so have attempted to sort it now.

So, only 4 weeks later than promised, it returned from the bodyshop! Thankfully, I seem to have got the job I was promised, so that's a relief.

As said previously, I was initially going to keep the hull white, and even the top deck. Like this:

http://img.photobucket.com/albums/v698/ManorQuay/Untitled-1.png

I wasn't fully decided though, and also liked the look of this (ironically the colour scheme and graphics it would have had originally)

http://images1.americanlisted.com/nlarge/2001_yamaha_waverunner_gp800r_22128821.jpg

I was drawn to these styles because reproduction graphics are available. I'm not much of a fan of some of the aftermarket stuff - of the prices! So, given that I wanted vinyl, I was fairly limited on choice.

I stumbled across the final style though, and knew that was the one I wanted:

http://www.dualaircraftexhaust.com/GP1300R-IMGResize4.jpg

I had the vinyl reproduced to read 'GP800R' instead of GP1300R, and set about the mission of discovering the paint code...

It transpires that Yamaha don't release the codes, so after taking a USB stick full of 'Deep Purplish Blue' ski's and Team Yamaha blue R1/R6's to my local paint supplier, we came up with 'Lamborghini Candy Apple Blue Pearl' as a suitable very close match:

http://i36.tinypic.com/28urr4.jpg

I decided on 2K base for the hull, and antiscratch laquer over the whole thing.

Here it is after I collected on Saturday morning:

and after beginning the refit

Can't wait to get the vinyl on. :)

Cheers for looking. Will keep you up to date on this - if you wanna be? lol

Looks good mate I had a 93 Seadoo xp and loved it to bits but was worse than a Nova for needing spending on it

Cheers Andy. It's good to mess about with something that's not a car for once. Although they're also barely related to a bike, which came aa a bit of a surprise. I expected more similarities. The engines are mental really. No clutch/box (newer and larger stuff have neutral and reverse) it just trawls as soon as you start it, so recovery can be interesting lol

Thanks Graeme. I looked at Seadoo XP and SPi's before opting for the GPR. They remind me of most of the skis I have rented whilst on holiday. Love the in ya face colour scheme on lots of them too!

What was up with yours then? Generally speaking, if flushed and washed after use (if used in salt watr) and properly winterized, you shouldn't really get many problems, but it all depends who has had their hands on it before you I guess!

Did you use yours much? I have added around 24 hours to mine since buying, so although to some it may seen unreliable, it's actually not doing bad at all - i'm sure you can understand that mate.

Obviously I am.insured, but I do find hilarious and a bit crazy that anyone can just turn up to an open slipway, stick it on the water and away the go, causing all kinds of issues.

eBay skiers they are known as, no PFD, radio etc etc and give us a bad name. I like to think I am slightly above that level lol

Cheers Dave, yeah it is a stunning blue. Some of the cars painted in Yamaha DPBM/Lambo Candy Apple blue on Google look amazing.

Refitted some more parts today, good to get some bench space/Escort interior space back. :)


Overall, I am happy with the paint job, but when I removed the masking tape from the side air intakes and fuel tap knob, it took a bit of paint with it, and left a lip.
Luckily these areas are covered anyway, but I still don't want the paint to lift obviously.
http://img.photobucket.com/albums/v698/ManorQuay/20121023_145827.jpg

Good job I have the right tool for the job lol
http://img.photobucket.com/albums/v698/ManorQuay/20121023_145838.jpg


I wasn't looking forward to rivetting the air intake scoops back on. A rivet gun that is known to 'spring' when the rivet finally snaps, and fresh paintwork are never a good combination. It went back on fine though. You can see the white overspray from the previous paint job. This is/was on a lot of parts. I hate lazy painters. I removed almost everything that wasn't permanently bonded to the hull.

The scoops only needed cleaning up along the bottom edge though, the rest is never seen.

Unsure what this is, as you can see I have labeled it as 'unused'. As it was unplugged when I stripped the thing down. It goes to the sensor to the right of the hood catch in the second pic.

http://img.photobucket.com/albums/v698/ManorQuay/20121023_150615.jpg

I'm thinking it is left over from the oil injection system. Maybe it's for the oil level, as the oil tank itself has two tails of wire coming from it in, I am sure, the same colours.

Another good thing about stripping it right down is, after the escapade of it being on it's side on the beach (you can see the paint damage down one side in the pic with Dodger waist deep in the hull) the LH grip/trim control was full of sand, as it was buried. The side fairings and glovebox etc had loads of stones stuck behind/inside them, and the hull itself wasn't shy on sand and stones inside!

Gotta be a good thing to get rid of all of that.

I think I will have a look at how to convert the grips and starter controls etc onto the MX bars later on.

I would have had the rear handle fitted, but it had a paint run, so is being redone. As is one of the side sponsons. Should have them back this week I reckon - he doesn't get his lovely sofa cushions and ratchet straps back until I do, anyway.

Tell me about it - Japanese bike manufacturers are terrible with giving colour codes. Honda, Kawasaki, Suzuki, Yamaha, you name them. You can buy 2K paint off them if you're lucky. As for colour codes... not a words. Idiots! :wtf:

BTW nice to read about jet ski's - I've seen some jet ski engines in bits but other than that I know very little about them. :thumb:

Yeah it's a strange one. The way they guard the paint codes so closely, and change the mixture just a little bit every couple of years. I hear that Lamborghini were such a fan of Team Yamaha blue/DPBM that they copied it for themselves - obviously changing it just a touch for legal reasons. Hence it filling my needs perfectly.

Sounds like you have been in a similar situtation a few times then mate? CLICK ME (http://www.colorrite.com) That link may be of use, as this company make the paint for Yamaha and others under licence, and it apparently the only place to lay your hands on it. I never bothered as I wasn't colour matching to existing paint. If you are though, it may be just the job.

Cheers btw :) I find it interesting, and am learning all of the time too.


Spent a few hours on this today, and got a bit done.

I am being slow and methodical when going about the reassembly of the ski, for one important reason: Break down in a car, and you can usually just coast to the side of the road. Break down on a jetski, and you're in a world of potential sh!t. So everything has to be just right!

Plus, things take longer to clean, as there's little springs and bits and pieces everywhere. lol

My mate came over and gave me a hand with putting the bars back together. I knew these would be awkward, as when I removed them from the steering plate and split the grips to remove the cables etc, ball bearings and springs fell out of the side which controls the trim (jet thrust nozzles angle), they went back in easily enough, but it was still a three handed job lol

Back together with cables and starter button etc (Was gonna fit my Renthal MX bars - like the Seadoo on the video at the bottom of my post, but going to leave that for now)

http://img.photobucket.com/albums/v698/ManorQuay/20121027_220641.jpg

I cleaned up the front cover, it was full of bits of copper and brass from the coming together of the stator and bendix, and had surface rusted in the centre, and I fitted the new (secondhand) OEM stator. (Basically the alternator)

It's a shame that one of the corners from the copper winding blocks is missing. Shouldn't be a problem though.

A question. Would you say it's okay to reuse the rubber gasket in the above picture? I am unsure how much they cost, but was expecting to find one in the 'full' gasket set I purchased! Bearing in mind, this is where the water found its way in and started the whole bendix/stator road to destruction last time - but someone had used silicone as well as the OEM gasket, so I think it wasn't sealing because of this.
I have reused these gaskets time and again on engines (cam cover) as I don't think they compress?

Any advice? (I will find out how much a new one costs)

Cleaned up the flywheel/magneto too. It was also full of copper windings and pieces of brass trapped in the nooks and crannies.

See the dents from it throwing debris around?

Exhaust gasket faces cleaned up too. The gaskets were a right tw4t to remove, as they weren't quite ready for eviction. I am going to have to blow the pipes out like I have OCD to ensure all of the dead gasket and bits of sandpaper (scraper on it's own wasn't enough) aren't blocking the waterways!

I am surprised to see such imperfections in the castings on the waterways etc. I guess it doesn't have to be perfect though.

Speaking of exhausts, I am not sure who is aware of this, but the ski takes in water through the intake grate on the bottom of the hull, circulates it inside the engine to cool it, then returns it to the sea/lake etc via the exhaust, also cooling that in the process.

If any part of the exhaust fails (Such as the rubber coupler I split when removing the system and was told in no uncertain terms not to glue it.) Then instead of the water exiting through the tailpipe outside of the hull, it will dump it inside of the hull.

The first you know of that is when CLICK ME (http://www.youtube.com/watch?v=HjoJvJkJ8Jo) - This happens! (Fastforward to 1:10)

Sketchy! Lol I know I will be ensuring my jubilee clips are nice and tight. :)

nice project, on the re use of the rubber gasket, i wouldn't chance it for the comparative cost, when new they have a round profile which gets squeezed flat when you fit the cover, and when they have been in use for a while, they stay flat, so don't seal as well when you re use them

Ordered a new gasket to be on the safe side. Also got a new speed sensor coming, as when I had the jet pump repitched, I used thread lock on the speedo bolts - then had to pretty much destroy it when I wanted the ride plate off this time.

Not the end of the world, as it was a little damaged anyway. Most people say just to leave it and run GPS for an accurate reading instead.
I would prefer everything to work as it should though. If I break it wave jumping then I won't be replacing it for a second time mind.

I can't refurbish the starter motor either annoyingly. The shaft on the commutator is measuring in at 13.2mm. I'm not gonna get a bearing to fit that. Guess it's more worn than I first assumed.

Refitted the bars and some other stuff. Should hopefully be fully back together and back in storage in a couple of weeks.
Just taking my time cos the weather is crap.

Next up is to give the engine a once over, and remove the overspray/paint from the dodgy masking on the previous white paint job on the gunwale (rubber bump strips)

What's the best way? Thinners and a rag isn't really making much of a dent, and fine Scothbrite etc is turning the surface matte.

That's the main reason you wear a wetsuit! Fall off the back of a Yam and I reckon you could get one from the 'visibility water spout' lol

Wave jumping is immense fun. When you're in the chop you see it rolling towards you and just go for it, expecting one thing to happen: The ski be smashed to fcuk and the waves pummel you to death, but one of two other things happen instead, you either cut through the wave or the favourite outcome, you get air!

It's amazing how much stick those hulls can take. Can't wait to wrap up warm and sample the sea in the winter. lol

16-11-12, 06:44 PM
Got the new o-ring gasket, and I also bought a new speed sensor. This stuff takes ages to arrive. I reckon it's maybe coming from Japan, then the Yam dealers in America (who I buy from) forward it on.

Still no starter motor! The tracking info says it is still in the USA, and hasn't been updated since 03/11/12, at least matey says he will send me another if I don't have it within a week.

The annoying thing is, the engine can't go back in until then! Well, it can, but it's much easier to reassmble the starter gear. magneto, headers etc on the bench, then drop the lot in in one go.

See here http://www.pwcforums.co.uk/snapped-bolts_topic56557.html for two issues I am cuurently experiencing - due to other people!

You're right as well, cars are cool, bikes are cool, and PWC are. All in their own ways.

People who dismiss PWC as 'boring' etc usually are themselves ime!

33 on GPS would probs be 50 on a skis dream-o-meter lol A boat would be cool to fish from/have BBQ's/get pissed. At least you cant die (as easily) on the loch too. The sea be a harsh mistress. lol

Its definitley fast enough when you're in the chop :d

Had this problem:

http://img.photobucket.com/albums/v698/ManorQuay/20121116_151408.jpg
http://img.photobucket.com/albums/v698/ManorQuay/Untitled-2.png

The lower bolt (22) was snapped in the insert (24). The bodyshop done this when removing the bow eye - the only thing I left on the ski, so I could transport it.

The only way to rectify this, is a pain in the **** to say the least.

Needed to bray a hole through the inner hull with a 4" holesaw
http://img.photobucket.com/albums/v698/ManorQuay/20121116_151750.jpg

Not having any winter ski clothing, and an old Ford that needs my attention means this isn't high on my priorities. Except I want to put it back in storage (nowhere ideal to ratchet strap to as I am unable to refit the bow eye) and not have it living under a gazebo/car cover in the yard.

So with that in mind, I broke out the tools:
4" hole cutter
20" of 3" I.D thin wall pipe
20" of 2" I.D thin wall pipe
Blow torch
longass 1/2" drive extensions, 19mm sockets
and numerous other items for foam removal (one being a butchers knife)

http://img.photobucket.com/albums/v698/ManorQuay/20121210_190818.jpg

After anal measurement and removal of copious amounts of smoldering foam/seriously itch skin, the nuts on the back of the inserts could finally be removed.

http://img.photobucket.com/albums/v698/ManorQuay/20121210_190654.jpg

Snapped, un-drillable, un-boltgriporanythingelseable stainless steel bolt can be seen in the lower insert.

Can you now see why I didn't wanna do this? :/

Should be able to have another brass insert made for free. Failing that, they are only a few quid.

Once I have one, I can fill the cavity with expanding foam (probably), and re-glass the circular blank that I removed. Then I am back to square one.

Can't see me refitting the motor this year.
A job for the springtime now. I guess I am winterized. At least it can go back into storage!

I also sunk it, on Monday. Engine was full of water. Right to the top of the barrels. :/ lol
Yep, I left a bolt loose on the exhaust outlet and it filled the hull about 2' deep with river water in maybe 10 mins of it bobbing about in the slipway.

Got it going again though, with no ill-effects and it ran like a champ for the next 2/3 hours and I had a right laugh. :)

Cheers lads, it is great fun. I would recommend one to anyone. I also had a shot on my mates 1994/95 Seadoo XP, when we were out. Those are great handling ski's, too and can be had for a steal.

Taking chase from the river 'police' never gets old, either. lol

Here's me inner hull, now that I have replaced the foam.

After expanding foam and with SMC blank back in place

http://i974.photobucket.com/albums/ae221/l14mnp/20140525_184833_zps800b2a30.jpg

Then silicone to seal

http://i974.photobucket.com/albums/ae221/l14mnp/20140525_185621_zpsbe293341.jpg

Not the neatest job by far, but it being water tight is the main priority. Anyway, a removable piece of floatation foam sits against the hull, there and the front bucket, so it isn't even seen.

Here's the bolt I left loose, that caused it to sink...

http://i974.photobucket.com/albums/ae221/l14mnp/20140526_154835_zpsd7ee371d.jpg

See the triangular pattern of inhex bolts in the middle of the pic? That's the exhaust outlet and due to me being a bufty and wanting to replace the rusty/oversprayed bolts with s/s items, I negated to nip them all up and the ski certainly punished me for it!

Considering it has been stripped to the bare minimum and rebuilt by a monkey with no clue (me), one loose bolt isn't bad at all.
Just a shame it properly kicked me in the bollocks, for overlooking it!

Always good to have something else with a motor ready to **** you over. lol

Just hope I can either extract this throttle shaft screw (unlikely) or free off the shaft enough to get the throttle butterflys returning on the linkage, so I can hoy it back together and get back out at the weekend.
