I have a '95 SPX 650 and I just bought it about a month ago. I took it out for the first time and it ran perfect the whole time. Left it sit at the dock and didnt know but the water discharge hose out of motor was broken off in the ski and water leaked in through there and filled up to top of motor. I fixed that problem now, Electrical box had a bunch of water in it. Fast forward to today... I replaced coil, plugs, new gas, Put all new connectors on wires in electrical box with dielectric silicone. Replaced the battery.It will run great for about five minutes and then once it heats up it starts to bog and will go off and on but continually get worse. Take it out of water and let it sit, same thing every time. It seems like it starts to heat up and then starts missing, I can smell the fuel when I am trying to get it started again so I was thinking not a fuel issue. I would guess electrical but not sure where to go with this. Any help is REALLY appreciated. Thanks.

Welcome to the forum Ken. Typical things to check when purchasing a "new" ski, compression and fuel lines. If they are grey, they need replacing. Either of these items could cause some of the issues you mention.
Look into these items and repost your question with the additional info in the 2-stroke PWC section if the forum.

If it ran perfect the first time out then it is logical that your issue is a result of the "sinking"....
If you do have Grey Tempo lines they and other things need to be replaced no matter what. If not, you will pretty much slowly destroy your engine.
I would open up all the various electrical boxes, spay the connections with WD-40 as it disapates water, get a good strong fan and lay it over the engine compartment and let it circulate air and help to evaperate any risidual water that may be hiding...

Thanks for the replies. Compression is good, gray fuel lines are still there. Have dried out electrical boxes and no changes. My other question is what gives power to the coil? I am wondering if something else is heating up and not working properly once it gets hot and causing the coil not to work properly?
