Prop Features:

The CompuThrust has four parabolic style raked blades of totally unique CAD/CAM design. The total blade area is about 40% larger than a standard three bladed 12inch diameter ski boat propellers providing enormous thrust for both social and tournament water skiing. The propeller is exceptionally smooth and it simply won’t “let go” throughout the full RPM range.
