I have an evolution .46 where the rear of the motor sits with no play in the mount... However as you move forward, the crankcase narrows, leaving space between the case and the motor mount. This allows the motor to swing left or right off centerline. What is the best way to ensure 0 degree side thrust. I Would like to do something other than the "eyeball it" method however motors I've worked with to date have not had this narrowing of the crankcase and I usually drop them in, slide for or aft for balance and secure.
