I have a 1997 Sea Doo XP. I bought this ski used, in June and have run it for about 10 hours. One trip out it started having reduced performance and could sputtered around. I read about the crappy default fuel lines so I decided to replace them hoping this would fix the issue. I also put on a carb primer kit, and cleaned out the carbs a bit, they were not bad but had a little gunk in them. The next trip out it started out well and was doing quite well for an hour or so, then is suddenly lost power, stuttered a bit and then died. Trying to start it I just got a click.
So that was the end of that day on the lake. I took apart the drive shaft in the back and looked to see if a bearing had seized, no it looked like it could use a little more grease but otherwise wise was fine. I took off the top end and saw the problem immediately. The second piston had some shards on the top of the piston and you could see it was very dry in there. It was running lean in that cylinder for sure, the other one looked ok.
You can see in the pictures one cylinder looks ok in that it has oil in it the other is dry and the top fo the piston looks scared up. The head also has pitting. I'm trying to figure out how this happened? What could cause one cylinder to not get oil? When oil injection fails does it usually do so only in one cylinder? I'm assuming the best approach here is to rebuild the top end, and flush the crank case incase any other shards got down in there. Would you all agree?
Also I looked in the manual and I can not find the part in the image below. I removed the cap and oil shot out. It looks like an after market thing but no clue what it is for.
