Went out camping this weekend and took my 95 Seadoo Speedster. Saturday it ran out fine and we had a blast. Today we took it out and it was great for the first couple hours then went to the beach and proceded to head out and all was fine until I seemed to loose power both engines wouldn't go over 5k. Also after this I shut it off to check things out and went to start it and it started it forward gear when it should only start in neutral. After loading back on the trailer I fired it up and it was acting the same. Once I got home I proceded to flush it and it ran perfectly normal and now only starts in neutral like it should. I'm stumped. What would cause this to happen. I don't want to risk this happening again a few miles from shore with my 3 yr old son.
