Other NEED Help please! 97 SeaDoo XP

[volkswerks]

UPDATED [I'm having trouble with my 97 Seadoo XP ski. I received this ski from a friend in pieces and have sucessfully reassembled it. The ski was rolled and took in water into the intake. Rings and pistons shot. All reconditioned, replaced and reassembled.



UPDATE: The starter works well and spins the motor. There is spark to the plugs as I gave myself a nice jolt. Gas to the carbs as I soaked my pants checking it. But the 3 don't like each other and the ski will not run. Is it inevitable that I will have to dig into the carbs for further review. The ski has an R&D jet kit with water cooled pipe, plenum air filters and a plate on top of the heads...More crap that is not stock that keeps me from getting anywhere with the service manual for it...

Thanks!

i had one at the shop with the same problem..i though it was the computer module to but i found out that it was the relay for the deskpost..so try that..

 

[volkswerks]

This relay is located where? under hood in motor compartment or in motor hood where I tied wires of desk post in...?

If the starter spins, but the engine doesn't crank, it means you should look at replacing your bendix. It's inside the stator cover.

Stick to Superjets!
The bendix for a Seadoo's all use a bendix in the starter nose, like a lot of car starters. (Except the 951 in all two strokes)
Must remove starter and dis-assemble the starter in order to replace the bendix drive.
Starter bendix drive could be rusty and cause this problem.

I think you should stick to Superjets as well but at least you are half right,the bendix is on the nose of the starter,however disassembly of the starter will get you nowhere.There is a circlip that holds the bendix on,it is under a collar that is spring loaded,push the collar down to reveal the circlip,if its rusted you may have to tap it down with a socket.Now take two pairs of slipjoint pliers and butt the ends together over the circlip,the ends of the pliers should be over the gap in the circlip,pull both sets of pliers back so the gap opens up on the circlip and remove the collar ,spring and bendix,you can test the bendix by holding the round part and rotating the gear part,it should only rotate one way and lock up the other way,make sure you rotate it a full 360 degrees when checking it.If it checks ok and was just stuck you can remove the rust from the shaft ,grease it up and reinstall the bendix.If it doesn't check out replace the bendix.If you didn't screw up the circlip too bad you can reuse it and just close it back up with a pair of pliers.Take a 14mm wrench and slide up under the collar,now bend the circlip together while pushing down on the wrench,the collar will slide back over the circlip when you have done this correctly.Reinstall the starter and go ride.

Thanks so much for that description! I was reading/searching this site and PWCtoday.com for information and wanted to check out the starter before I go out and just buy a new one. You've given me some hope. I am so close to getting this ski wet, I can feel it...um...I think I may have pee'd myself.

Supertune, I have owned 9 seadoos including 800's. I've replaced the bendix on a 800 starter as well. No need to rip on me for offering a little advice on what to look at. Pulling the stator cover is one way to see the condidtion of the bendix, and also see if there is water inside the cover that made the bendix rust. Pulling the starter is the best way to do the work, I aggree. It's just nice to see that there are no water intrusion problems as well.

As for superjets, I'm no expert, and actually didn't even own one untill 2007. I've been a kawi/seadoo guy since 1990.

Anytime bro!

Anytime bro!

So that was sweet. The starter works and turns the motor now that it was pulled and de-rusted. I have spark, I have fuel TO the carbs. I have no run action though. All the pieces are in place...just not running.

I pulled the spark plugs and they are clean, I tried for a bit afterwards but never pulled them again to verify if they are wet with gas. I found a bunch on clogged carb filters. Is that my next avenue? Dig into the carbs as it has been sitting since the fall of 07?

 

[Pro-pulsion]

Yeah pull the carbs and clean them up well. There is a little filter inside of them that clogs up real easily. Plus if the fuel wasn't conditioned before the ski was put away you'll most likely have plugged ports as well. I've found that the best thing to use when clearing progression ports etc., is a single strand of wire found on either a bicycle brake cable or something small like that. Those strands will fit into any of the ports. If the diaphragm is stiff like cardboard and crackles when you flex it, then it needs to be replaced. Another good reason for the carbs to plug up is if the ski still has the gray Tempo lines on it. I'm not sure what year they finally did away with those lines, but they deteriorate internally and send the rotten material into the the carbs plugging up those screens pretty badly and quickly. If that ski has those gray Tempo lines, trash them right away and replace them or you will have to clean the carbs before each ride.
