    Porpoising Issue

    Have a 3-seater 90hp and when it gets up 50 mph it starts porpoising, gradually getting worse. I was riding on a flat canal, 170lbs, and the turn nozzle is mounted in the "down" position. This can't be normal on these things???

    You might try a WORX ride plate and the nozzle in the level position.

    I'd like to know why mine is the only one porpoising, is it the only one??? Does it with the steer nozzle in either position. Only 4 hours on ski, no fun to ride above 45mph (it's like riding a horse, just not as smooth!)

    You mentioned the nozzle is in the down position. Can you post a picture?

    What I mean is, the bottom bolt on the steering nozzle has a bushing that can go 2 ways, and it changes the angle of the nozzle. Ive tried both ways, and it does make a difference in the way the bow rides, I still get rather violent porpoising above 45mph on flat calm water.

    My stock ride plate does not have that much angle on it.
