    185 hp was running on 2 cylinders

    What could happen?

    My gtx sc ran for a little while on two pistons. It never have done this before. It then ran fine, went full speed. Is there something wrong with the valves or is it as simple as a bad spark plug? I noticed the spark plugs are facing corrossion on the outside due to water retention there. But there should have been some contact left for spark. Also, I was turning the motor on the trailer and it is turning slow. It is not the battery as I have swapped it out. Otherwise, the ski has 80 hours and it was running fine. It is running fine now too. I just dont want to blow something.

    Spend $12 at a dealer and get new plugs and see if that helps... Ron
