I am at my wits end so I'm looking to other experts for advice here. I have a 2000 Mooba Kamberra that has some pretty bad cavaitaion or vibration issues.. The problem is when under heavy load, such as towing a towable, the boat cavitates hard when truning right. I originaly tought the issue was cavitation so I had my prop refinished to no avail. The more load on the boat the worse the vibration is and the lake conditions don't seem to play into, it does it in calm water as well as rough water. Any suggestions or thoughts?
