http://www.stevescustompr…rop_shaft_engine_height_follow these instructions. Pay attention to your trim guage when your motor is level and only go maybe a hair past it when your triming up on the water. I had the same problem running a 27 tempest on a 250xs cougar. I order a 26 fury but have not tested it out yet, but i followed these instructions and handling improved greatly with the tempest and I hope it will get even better with the fury. Steve said what is happening more than likely is the prop is going to far past level by triming up too far and “pushing” the tail end of the boat down and causing it walk around, or something like that. Try it out it wont cost you anything but time and i think it will fix your problem.
