Alpha 4
Mercury is discontinuing the entire Alpha line of props. We will sell until no longer available.
Alpha 4 props listed for sale on this site remain available.
The aluminum Spitfire is the recommended replacement.
Mercury recommends the 4-blade SpitFire propeller as the aluminum option for 90 CT - 150 outboards and Sterndrive applications. When transitioning to a SpitFire, increase 1" of pitch from the Alpha 4.
