I have a fiberglass 22' cuddy with a 200 hp yamaha outboard. When I go underpower it starts to pull to the right, as I increase power it gets harder to hold straight to the point that I have to back off to keep control of the boat. It is cable type steering. Has anyone had similar trouble and what did you do to fix it? I do have trim tabs and adjusting them helps a little. Can anyone recomend a boat mech with this kind of experience?
