Oil Tank 95 GTX Question

[Underwater78]

My Seadoo is a GTX 95 and when i got it the last owner took the oil tank and seal the holes for the plugs, i been having some troubles with the engine, a lot of beeping, not sure overheating, now my engine have troubles starting and the seadoo dealer told me is better to put a oil tank, i been mixing the oil with the gas but since a have issues with the engine i guess i should put the oil tank, my question is can i put a 98 gtx oil tank in my 95? the tank is bigger but is free, in the dealer cost $70 for the 95. Thanks.

Oil Tank

I don't see why not as long as it will physically fit. Also it need to be secure.

The problem with premixing is often you get more oil than is needed, as its hard to mix on the fly, the marina's where I go don't pump premix.

This don't sound right to me ...........

Tank is removed? Is there a loop line?

DOES THE CRANKCASE AND ROTARY VALVE STILL HAVE AN OIL SUPPLY FROM SOMEWHERE?

:bigear:

Help me out here Lou, is this 95 motor a 4 cycle? Has a crankcase with oil & filter?

2 Cycle

A 1995 GTX is a 2 stroke, SeaDoo only started using 4 stroke engines around 2001 (I think), and then only in some models.

So, i wonder how the crank and RV are getting along on this motor? I just passed on a 95 SP that had pump removed for pre-mix, ran 20 minutes before eating the brass gear, repaired and sent out for another 10 minutes, then stopped again, returned to repair shop, told the guy it need crank bearings, quoted him $900 for the repair so he sold the ski & trailer for $600. What i didn't get was all the while neither the owner nor the repairman he trusted knew that by using the block-off to remove the pump, the crank and RV still need the same 2-cycle oil from the tank or other source to have lubrication. I asked the owner if he did the block-off kit and what did he do with the two larger oil lines that connect ot the block. He said he installed the block-off and secured bolts into the tube ports on the block for the oil lines. I let him know of his error in the most tactful way i could..........

I hope this isn't the case with this 95 GTX.....

So i ask again. How is the crank and RV being lubricated in this motor?

Premix

A 2stroke unlike a 4stroke has roller or ball bearings on the crankshaft and needs little lubrication. On 2stroke engines there is enough lubrication with the fuel mix to provide sufficient lubrication to the crank bearings.

Other 2stroke engines use this method, outboards, chain saws, string trimmers, older motorcycles (dirt bikes).

The rotary valve is a different problem, most people that use premix simply leave the oil tank in to provide drip lubrication to the rotary valve. I understand you can also make a closed loop with the oil line to the rotary valve to provide sufficient lubrication.

I have never and probably never will run premix, so I'm not advocating useing premix, I am simply trying to explain how premix works.
