    Seadoo runs on trailer, not in water

    I have had a couple ski's now, 96 GTI and 95 XP thay run and idle good on the trailer, put them in the water and they stall out and wont run. Is there a known issue i can start looking for? Makes no sense to me.

    yep, good old two strokes, had the same problem. You have a dead cylinder on each, two strokes will sound great on the one cylinder not in water. Remove one wire and start then switch to find the dead cylinder. Could be a bad plug, carb issue or dead cylinder.

    When was the last time they did run good in water & how long have they been sitting?
    Have you changed the old grey fuel lines? fuel valve or internal carb filters clogged?
    If you're getting them ready for the season, you might as well service them.

    Probably you have a problem in the carb/s. You should clean it
