787

My jetski was trailered on my driveway for the past two seasons. When I summerized it, it started right up with the hose connected and ran fine for a few minutes. When I took it to the lake, it powered off the trailer (normal thrust) but overheated after a few minutes. I flushed it again, and...

Hello, I am currently having some issues with my ski. When I go to start it (with a full and tested battery) it will turn over and than stop turning over like I am letting go of the starter button. Turn over for a couple seconds and then stop for a second and repeat. However, I have noticed if...

Just bought this 97 Challenger 1800 and put it on the water for the first time last night. Twin 787 Rotax's. Dropped it in the water and took it a few hundred yards up and down the river to make sure everything was going to run okay. Picked up the family from the dock and helped friends load...

Click below for video Starter ? 1996 Sea Doo GTX - YouTube This is the sound the ski makes when I press the start button. It will eventually start but it seems like the starter is not catching. Brand new battery installed as well.. The ski was re-built from top to bottom a little over a year...

Hi there, New here. I have a Seadoo 787 GTX 1997 model that has a bad motor. I' ve split the motor and have all the new replacement parts except for the counter balance Shaft external seal. The Old bearing seal was a metal disk with an O ring and then a large c snap Ring to keep it in place...

I'm looking for some input from Seadoo engine gurus to shed light on a failed engine. I recently purchased a 99 GSX RFI fixer upper pwc. I am not knew to PWCs but this is my first Sea-doo. I didn't water test prior to purchase due to a damaged impeller but engine started easily on the trailer...

Hey guys, I just completed my first ride on my 1997 XP. I bought the XP broken and rebuilt the engine. Bored it .030 over. But anyway I have a few questions and one issue that I need to address. Question first, let's start off by saying the VTS is broken, working on that... But I set the...

Hey all so im stumped with a problem i have been having, hoping someone has an answer. My problem is the ski tops out at 50 mph (which i feel should be slightly higher) also when im WOT going straight it barley reaches 6700 rpms and if i start to turn left i loose about 300 rpms. If i turn...

If you don't want to read my long winded story below then please just answer the following question: Can a bad DESS post cause the engine to backfire while riding in the upper RPM range, push out and bend the rotary valve, scrape up the RV cover, and then cause the engine to quit? If you...

Hello, I recently picked up a 1997 XP that needs to be rebuilt really cheap with trailer. So i started tearing into this thing knowing that it needed a top end and really hoping the bottom end would be in good shape. But the previous owner had tore most of it down and saw that it needed a top...

Hi guys, I'm restoring 1998 Speedster with twin 787s. I made a mistake and took both wires on both engines off spark plugs before taking a picture.. I need to know where wire #1 and #2 go on the engine, manual has a diagram (parts catalog) but I'm not 100% positive if it is correct and...

I need to remove the starter motor from my 2004 GTI LE RFI It is the 110hp, fuel-injected, 787 RFI-engine, I think. I've tried to follow a procedure I found here, but it might not apply to my specific model. It mentioned removal of a black negative cable from the starter that I didn't have...

Any info on where to find an affordable CDI for my 1996 Seadoo Gtx 787? I've only seen a couple on Ebay. Seadoo is asking $900+ ... Is there a way to repair the CDI itself? Circuit diagram? Thanks!

Any suggestion for sudden stalling ? Starts easily- runs well under load then immediate engine shut down 2-3 minutes later. No bogging or hesitation. Will not crank unless key is removed and replaced. Then will easily start and runs well for 2-3 minutes. Are there any sensors that will...

97 Seadoo challenger 1800 Good morning guys, I have motor that I suspect was hydrolocked. I was running the boat, came into shore to play. Three hours later I came back to wakeboard around and the port motor would not turn. I was able to get the drive shaft unstuck, and now the motor...

Hey everyone. Finally go my 98 SPX up and running today and I need a last bit of advice before I take it out on the water. I'm 99% sure that there's no issues with the oil pump but to hedge my bet on that I'd like to add some oil to the first tank of gas I run through it then check the oil level...

Does anyone know of a way, short of removing the engine, to eliminate any water that may be at the bottom of the crank case? I don't want to blow the balance shaft if some water is sitting down there and there is no balance shaft drain plug on the 1996. Any chemical I can get into the...

Hi guys! can anyone tell me how to get the the pipe out of a 96 xp/787 without splitting it? I hate realigning those things. The engine compartment is pretty tight and the pipe doesn't seem to want to come out in one piece. Will it come if I put the exhaust manifold also? Thanks in advance.
