    Weird Mis-Fire 96 XP

    I picked up a little 96 XP to play with. Im trying to figure out whats up with it.

    Starts and idles great. Revs fine on trailer. When in the water it will run WOT for about 2 seconds before it bogs down and starts misfiring really bad. If you let off it will idle fine.

    If you shut the ski off, start it back up and open it WOT it will rev up again and bog within 2 seconds.


    Carbs are rebuilt,new fuel lines,etc about a month ago. the ski ran fine last week. Seems like a electrical issue to me? Any ideas on what to check guys? Thanks!

    Sounds like the rectifier is on the way out.

    So if I were to unplug it will that allow the engine to run correctly and just not charge the battery?
