Hi, I am hoping someone can help me. My seadoo worked trouble free for 3 years when I bought it used. Out on the lake one day the engine just went slugginsh as if the water intake was clogged. We stopped the seadoo and checked the water intake and it was clear, when we tried to start it, it turned over sluggishly and would not start. I took it to Snow City Cycle in Toronto and over the next 3 seasons they changed everything but the crank shaft. New battery, starter motor, stator, re-bored the heads, new pistons, carburetor I was told was fine but still changed all the filters, diagram, & gaskets. They replaced the computer to test it found the same problem so re-installed my original compluter. To date the same problem $2000 later they have given up on it and told me there is nothing else they can do. It starts first turn and gets up on plane but after 10 minutes the engine bogs down again and I have to troll back to shore. I am hoping that someone has come across this type of issue and can help me. Thank you in advance for any help you can give.
