hi, I have a seadoo gtx 155 2011. recently they change the camshaft to a 21 ( from the 51 stock )to gain some power.
Now the jetski, tested out of the water, when I accelerate it, the revs stays up, near 3k -4k and when I accelerate again, they goes almost to o before going back to normal. the funny part is that this doesn't happen in the water. is this a faulty throttle or incorrect timing for the camshaft?
