putting a 350 merc in boat that had omc cobra originally. i've gathered alot of parts hoping to get the right stuff. motor is newer merc, but i have the exhaust parts, transom, gimbal, outdrive circa early 80's merc. here's the problem. the inner transom shield that i have is alpha series, the rest of parts are pre-alpha. i've discovered that the motor mounts on transom plate are alot narrower for alpha series. bellhousing on motor is pre-alpha. wider. questions: 1) will the omc cobra plate work? 2)can i change the bellhousing on motor to an alpha series (narrower motor mount) or would i run into flywheel size issues? not utilizing power steering, but cannot find a plate for pre-alpha that doesn't have power steering. answers, ideas, thoughts?
