Performance Enhancing Aluminum HydroFoil

This product is designed to help with several common issues. 


Some benefits include:

Lower on plane speed

Less blowing out

Less prop cavitation

Ability to run prop higher


Each hydrofoil comes with the needed stainless steel hardware


There are 2 styles that are available. The difference is strictly a personal preference in appearance! The most common style has cutouts. The theory behind the cutouts in high performance applications is that they allow the propeller to spin higher RPM’s.
