96' GSX Oil question (Quicksilver PWC Oil) Seadoo

[firemann32]

Yes its another oil thread and I did try a search but n oluck.

I picked up a Seadoo over the winter 96' GSX (I have 2 other Yamaha's 96' & 98')

Well I can run TC-W3 in the Yamaha's but the Seadoo manual says not to use it so what do I need to run in the Seadoo?

I was thinking QUICKSILVER PERSONAL WATERCRAFT 2-CYCLE OIL, its says its
Engineered to meet the high-performance demands of SeaDoo WaveRunners and other PWC's specifying the use of an API-TC oil. Synthetic blend provides high temperature stability increased w ear protection and reduced smoke emissions

Any suggestions?

GEEEZZZZZZZZZZ !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You can't swing a dead cat around this place without hitting an oil thread !!!


But since you are a Yamaha guy... We will forgive you.


No, our SeaDoo engines don't like TC-w3 oils. there are 2 issues. first... the TC-w3 oils can not support the HP levels of the Rotax engines. (HP/cc) second... on most of the Rotax engines, they use a rotary intake valve. that valve is run from 2 gears off of the center of the crankshaft. That section of the engine is fed with oil from the injector tank, and TC-w3 oils don't do well in protecting those gears.


You can use any oil you want that is API-TC certified. (not just "meet or exceeds specification") The known good oils are: Bombardier XPS (mineral, synth, or synth blend) Amsoil interceptor, or Quicksilver PWC.

If Yamaha would spec API-TC oils... their engines would live longer. It's very common to find a 97 SeaDoo XP (800cc 110hp motor) with a factory engine still running strong, but I can find 2000 to 2003 GP800's with blown engines all over the place. I'm not bashing Yamaha (I'm a convert, and still have my superjet) but good oil goes a long way in engine life.

Just an FYI on using the proper oil....


I just restored an 1990 Seadoo Si. The original owner only used XPS mineral oil, and the 20 year old engine still shows 145 psi in each jug... and runs like a champ!

The worst thing that happens in my area is someone purchases a used ski and has no idea what oil the old owner used and when they mix it forms a gel in the filter and then you need compressed air to clear the tiny lines out so the new oil will flow - part of buying a 2stroke is knowing to get the old oil bottle so you can keep it going or drain it on old clothes and flush the OEM oil system with kerosene while running on premix then put in the oil that is local and you remember to have some on hand, then when the motor is drinking you can just gas and go.

LOL as a mod on a motorcycle site I know how the oil threads can be so I made sure to use good key words in the title.

Cool then that's what I'll run the QUICKSILVER PERSONAL WATERCRAFT 2-CYCLE OIL, I'm still trying to find out what oil he used in it I guess I could always just drain the oil tank and start fresh.

 

[firemann32]

Well he said that he got all his oil from the local watercraft shop, which I know recommends Bombardiar oil, will that mix with Quicksilver?

What board are you a mod on?


If you don't know what oil is in the tank... yes... drain it, and use it in your weedeater, or give it to a buddy with a diesel truck, and let him pour it in his fuel tank.

After you drain it... clear the 3 lines going to your engine, change the little filter in the oil line going to the injector pump, refill the system with the oil of your choice, and finally... bleed the injector pump.

While you are doing that... make sure the hoses to the engine aren't leaking or cracking, and replace the 2 little hoses from the injector pump to the engine. (a couple $$$ from the SeaDoo dealer when you buy a new filter) You can re-attach them with zip ties.


FYI... unlike many of the oil injection systems out there (cough: yamaha cough) ... it is very uncommon to have a SeaDoo injector fail. Any issues are normally from the filter being clogged, or one of the hoses breaking because of age.

thats bs man i have lost 2 doos to faulty injection pumps. the rear cylinder mainly....... quite a pisser. i have about 3 of them sitting on my crap shelf. they can go bad and alot of ppl i know have blocked em off and premixed because of this. although... cough.... cough... my 89 kawi still works great though. lol

 

[Dr Honda]

OK... I'm going to start by saying... this is not a flame... I'm just asking Q's.


You lost 2 rear cycl? Sounds more like a lean run than a bad oil pump. Since it's an injection system, if it goes lean... the oil doesn't transport into the engine.

How old were the engines?

Did the pump actually go bad, or did one of the injector nozzles get plugged up, and starve the engine?

I'm not saying the system is perfect, and there are failures... but most failures can be avoided with yearly maintenance. Most oil injection issues we see here are plugged filters, plugged nozzles, or broken/cracked hoses.

I switched my 96 GSX to Quicksilver Premium full synthetic and 2 rides later my engine ripped a hole in the bottom. Go figure.

I switched from Bud Light to Miller Light and two days later my wife's uncle died......Who'd a thunk it??? :boxing_smiley: :rant:
