Just wondering what exactly the purpose of this is. I have A Merc 4.3L Alpha one recently purchased and there is not one on the out drive. Do I need this???
Doesn't look like I need it. Boat has power steering. Excited about tomorrow though. Trying out a Quicksilver 5 blade 19P SS prop. Hope it works well with my set up. I am getting a super deal on it if it does....
