Right engine problems on the speedster

[twatkins]

i have a 98 seadoo speedster and its the twin propulsion system with the 2 motors. its mainly run in freshwater but we bought it used from the coast so it has seen its saltwater days. well a couple of months ago we got it out and tried to get it ready for the summer. the left motor runs fine, but the right motor wouldnt turn over. the starter would just click. well we took the spark plugs out and sprayed some penetration oil and lube in theere and let it sit for a week. we eventually got the cylinder to free up and spin over. then it started fouling out alot of spark plugs. we figured this would be normal because of all the oil we had in the cylinder trying to free it up. well after about 6 plugs it ran fine. we took it to the lake and it ran great for about 3 hours. then the right motor started having problems AGAIN. i would have to choke it to start it then it would struggle to run at about 1500 rpms. i would give it full throttle and it still wouldnt get above 1500 rpms. and it wasnt a normal 1500, it was like a struggle to run 1500. and then it would cut off and it just wouldnt start again. does anybody have any clue what could be wrong? the left motor runs great, just the right one is giving me alllllll the problems. Thanks

you may have big engine problems. if you had to "free it up" it most likely needs rebuilt.

do you know how difficult that is? like is it something i can do in my shop or should i take it somewhere? can you leave the motor in to do that or do you have to take it out? and where would i go to get the parts to rebuild it? thanks

do compression test, and post your results, but sounds like you need a rebuild.

agreed with seadooya. check sbt for prices for the engine.
