Alpha One

The MerCruiser Alpha® One drive earned the title of "world's most popular sterndrive" because it delivers reliable performance in a value package. 

To improve the performance and overall efficiency of your stock 3, 4, or 5-blade Alpha 1 aluminum propeller, try Signature's stainless steel propeller. You'll be amazed at the difference it makes. More speed, faster planning with less cavitation, and all-around more efficiency.

The Pleasure Three, Pleasure Four and Pleasure Five lines of Signature Stainless Steel Props replaces MerCruiser Alpha 1 from 16" to 24" pitch; right hand rotation.
