When my 2010 Axis A22 w/475 hours is sacked out for surfing (goofy side) and we hit another wake I get a high freq momentarily vibration . Almost sounds like a binding that resonates though the boat and an engine tone change. The sound/vibration last about a half second and corresponds with each wave we go over. I used to think it was just prop cavitation, but it seems to be getting worse - maybe it is and Im just adding more weight these days and should back off. (1100 in the corner, 750 on the side seat, and 950 in the bow, 2 adults in the boat). I wanted to ask if anyone else has experienced something like this or think it might be a bigger issue like shaft alignment or transmission that I need to have checked out. ** A DIY surfgate cant come soon enough **
