I have a 2006 Sanger V215 and when turning around while towing someone I occasionally temporarily lose steering. I ride in the Sacramento river and the Delta so my turns have to be somewhat tight. It seems like the more weight I have in the boat the worse it gets. I normally just run the stock 1000lbs and an extra 300lbs of lead in the back. Could it be the prop cavitating? I have the stock prop which is an acme 525 3 blade.
Thanks for the help!
