Theres been alot of post on here talking about overtrimming causing problems. I was wondering if there was an exact way to get you boat to that "perfect" trim setting. and mark the gauge for future referance. Any help would greatly be appreciated. I have a TR-196 PD with a Merc. 150 hp XR6 . Any prop suggestions or setup tips would be helpful also. I'm running a tempest 23".
