Starting to Revive 2002 GTX DI - New to PWC and See Doo (2024)

Hi To All - Got a 2002 GTX DI from a friend, who trailered it behind the barn for last 7 years. New to PWC. Have Parts Catalog but not Shop Manual. To start the revival, drained all fluid and cleaned gas tank twice. Blew out all lines. New spark plugs. New battery. It tries to start - almost - so decided to go further. Ordered new fuel pump, new injectors and rebuild kit for air compressor. Jet pump looks good and can't decide whether to rebuild; buy new one; or just try to see if old one will work.

Hoping to get some advice and guidance and if our approach needs to be added to. For example:

*in order to change the air compressor, a video we watched shows to pull the harmonic balancer. Is this correct? Are there cautions regarding reinstall of balancer?

*is it advisable to rebuild a jet pump? Are there tricks to it? Where is best place to get the correct rebuild kit?

*If going to try our luck with the old jet pump, what is minimum required maintenance and repairs needed?

*Seen on other Post that some of these components - fuel pump maybe? - need to pressure tested. Anything else need to be tested? How to test please?

THanks for your time and help.

Steve

You should have come here first.
A DI that hasn't run in years is 99.9999% of the time not worth the trouble.

What fuel pump did you buy, hopefully OEM.

I would check fuel pressures before messing with the fuel pump or air compressor. You can contact this Gentleman "ajp25564@gmail.com" (Tony) he builds fuel pressure tester adapters for the DI. They work great !! I've done the air compressor rebuild with the engine in the ski and it sure ain't fun but I hate pulling the engine on a DI when I don't have to. Probably just as much work but....

I wouldn't rebuild the jet pump unless I had a reason. If there was oil in the pump the internals are likely in decent shape. You might want to replace the lip seal. Good Luck !!

Miki - On Amazon.. states it's a HFP brand by Quantum Fuel Systems, CA. and claims to be OEM for See Doo GTX DI.

Thanks for the info.... But have already got air compressor rebuild kit and will pull impalor blades today and do the rebuild. We'll see how it goes. The jet pump was full of oil; no blade damage and spin freely with no apparent bearing squeal, so going to replace the o-ring on cone. What is the 'lip seal' please.

I would do that it will make it easier

Best would be oem but you can get rebuild kits at alot of places. You will need a press to do it.

Oil Change if internals are good. replace the shaft seal and bearings if damaged.

IMO, I wouldn't throw new parts at it, take it one step at a time, OEM is the best to have on these skis, so keep it stock as much as you can.. If you buy parts that are electrical or have seals ...go OEM as much as possible. If you cant, check them out well, most aftermarket stuff for this (in the categories I mentioned ) are terrible. I also wouldn't do any upgrades, its a waste of money, these skis are built to (almost) their limit. Upgraded parts are worthless, unless you go full racing mode.
First thing to do is check compression, make sure the bones are good. Then verify gas and spark. Getting new injector or cleaning the one you have is a good move. New battery and spark plugs is a must as well. Check all hoses. I would also take grounds off, clean them and reinstall. Grounds can be an issue with skis.
If you haven't done so get the maintenance manual, it will help with issues, they are free online.

lets us know how it goes.

Hey Grim -

Thanks for the info! This thing has set up behind a barn for seven years.

But with just new plugs and fresh gas, this thing almost started! So we just got the old air compressor out and about to install the rebuild one. Waiting on new injectors. New fuel pump delivered tomorrow. New battery. The pump still has all the oil and no sign of water and no blade damage and spins freely with no sound of bearing distress. Going to change the o-ring at cone and seal lip at bulkhead.

Thanks for advice about checking and cleaning all ground wires.

About maintenance manuals... had a real hard time finding manuals. Finally bought a parts catalog manual on EBay, but really need a Shop / Maintenance Manual. Any guidance on where one for a 2002 GTX Bombadier can be found?

Thanks so much!

Lip seal is at the impeller end where the shaft comes out of the pump. It's obviously not leaking but they lose their elasticity as they age. I have them in stock so I can change them pretty quick. I think you're OK leaving it alone.

There is absolutely no reason to mess with the compressor if you have good pressure. It is a total pain in the azz especially if the engine is in the ski. You need to be able to test the fuel pressures. Sometimes it is only an o-ring leaking. Good Luck !!

Thanks... rebuilt compressor in. Waiting on new injectors but they're way late for delivery. Soaking old injectors in Mineral Spirits and may have to re-install them... just to see if sky gonna go.
