So where to start.. about 2 months ago I bought a 96 seadoo xp that was running but needed a lot of attention. It has good compression in both cylinders (148 and 149)and was able to go about 49mph max so I knew something wasn't perfect. I first got a carb rebuild kit (don't even get me started on that Amazon crap vs oem) and without knowing much about carbs I rebuilt using the aftermarket kit and replaced all the fuel lines, put in new filter and fuel selector valve. I was able to get it running ok after the carb rebuild after a lot of tuneing essentially had to give it a little choke to get it past 1/4 throttle and then you were fine. We will come back to the carb..
While out on a test run I was almost back to the dock and had my boat suddenly fill with water and long story short the impeller shaft had broken off inside the impeller (say goodbye to that impeller).. so then the spending rebuilding really got going. I got a solas imleller new bearings for the pump and a shaft. Also got a new carbon ring and all those parts since I was taking it out. So upon getting everything out im examining the skid plate hull ring and notice there was a ton of wear in the metal of the hull ring part of the skid plate.. so I ended up getting one of those too thank God for everyone parting these things out on eBay. It appeared after taking my wear ring out that the rednecks who owned it before me had put in a ring that was almost an inch short. I thought that for sure is what caused the grinding in the skid plate. So I replaced everything in the pump (pushing out bearings without tool is haard) and sealed it off with loctite and put in new oil. I then tackled cleaning and installing the new to me skid plate/hull ring and neoprene seal and lathered with black gasket maker under everything. Put the pump and nozzle back on and brought the ski with me to the beach to continue working on getting the carb right. I put in at the bay and after a few days of adjusting the carb going back and forth to the bay I was able to get the ski to hit 56mph! When taking it out after running it at top speed for about an hour I was hosing off the xp and I like to run it for a few seconds to push all that salt water out from the bay. Upon starting the ski i had what I belive is called runaway idle occur when I revved the engine just a bit. It pretty much pegged out at full throttle for a solid minute... so traumatic let me tell you. Pulling the lanyard spark plugs and negative terminal off the battery did nothing to stop the engine. In hindsight I could've plugged up the carb intake holes or install and battery kill switch.. whatever the issue happened and I was certain I had messed something up. So I first took it and checked compression which surprisingly hadn't changed then I changed plugs and decided to go put it back in the water to see if it would run. It ran but felt not quite right. We just got home from the trip and I took it out to the lake today to do a test. After a few minutes of mild cavitation the ski got worse and now won't go over idle.. the engine will rev and you can feel it spinning the impeller hard. Im thinking I killed the wear ring and the carbon ring.. upon examining everything from underneath visually looking through grate it appears that my impeller might be grinding into the hull skid plate again...... ahh has anyone had any issues with this too? Could running idle out of water caused this? I'm going to take the pump off again I guess tomorrow and see what looks worn. Any help would be much appreciated.
