Seadoo oil seal replacement?

[Cook412]

Hey everybody sorry if I posted anything in the wrong spot or didn't give enough info. im new

This is my problem: I have a 1993 seadoo xp that leaks oil into the cylinders and i am pretty sure that i have bad crankshaft oil seals. I am pretty mechanically inclined but new to jet ski engines. I am planning on changing the oil seals myself this winter and i was wondering, once i get the crankshaft out how do i go about changing the oil seals. I've talked to a few dealers and if it is too hard for my i may let them replace the seals if its not too much.

Thanks

It requires a complete disassembly of the engine to change the seal, unless it is really bad leaking, wait till it comes apart and/or pinch the oil line off when it's going to be stored for any amount of time.

it does seem to be leaking bad. the main reason why i want to change the seals is because the oil fouls out the plugs in two hours and i would like to have a full day on the lake without changing the plugs two or three times. I already knew i needed to fully disassemble the engine. my main concern is how do i go about removing the seals off the crankshaft...i was told to put the seals back on it requires a press or i could use something like a ball joint/busing press.

The crank seals are in the center of the crank. You have to have all the right equipment to press the crank apart. All the counter weights, rods, bearings etc... have to be taken apart. This is not the job for the average guy, I have access to a full machine shop and I still wouldn't do it. You can get a reman crank from SBT for $225

Heck, you can get a complete engine from them for $600

Thanks

Those leaking crank seals will cause a lean run and result in major top end damage. It is only a matter of time. Considering the age of your ski if your engine is original it is surely time for a complete rebuild. Just replacing the crank is only buying a little time. Spend the Winter installing a complete rebuilt engine and you can ride worry free for the next few seasons. SES seems to have the best prices but longer turn around since they rebuild the engine that you send. SBT is higher priced but they can ship an exchange engine tomorrow. These shops offer both 1 and 2 year no fault warranties. You will spend more on parts and tools trying to rebuild it yourself.
