    Hose routing for 1997 Seadoo XP 787?

    I completely forgot to remember which hoses go where on the engine after I took it out so now that I'm putting it back in, I don't know where which hose goes! Could someone take a few pictures of theirs and show me? Thanks.

    Are you referring to the ones that go onto the cylinder head??

    If so, it really doesn't matter....

    Before any one jumps my case here, it was an old racer thing to swap the water lines on the cylinder head so that you kept the top end cooler first. We reversed the water flow on all of our 785's.

    So I put everything together and I probably put something in wrong because now the oil container is drained and the engine is completely filled with oil, all the way up to the carburetor. What did I do wrong?

    On the oil reservoir there are only three oil lines. Larger 10 mm oil line at the top goes to the USA driver side rear of the engine. As for the two oil lines on the bottom of the reservoir the larger 10 mm line goes to the USA passenger side rear on the engine. The smaller 8 mm on the bottom of the reservoir goes to the front and just right of center part of the engine. This line also has an inline oil filter. I know my pics are hard to follow but it's pretty cramped in there. Ill do my best to send you a video following the lines but if you think they are all connected correctly then there is probably another issue. Pete is an awesome source to talk to. He sent you some info already. I'm a rookie at this but ill help however I can man.

    Pick Pete's brain not mine. I hope I help but I'm a car guy and new to water craft. http://www.cpjetski.com/ you have an expert trying to help. I absolutely don't mind helping you man if I can. But you should hit up the captain.

    assuming all the oil lines are in the correct place....the rotary valve seal has got a massive leak. This assumes the engine was rebuilt and this is the first time it's been installed

    The only other possible is that you've connected the line to the oil pump to the pulse fitting on the crankcase
