Four-blade Comprops are used as original equipment by many boat manufacturers such as Regal, Wellcraft, and Four Winns. Comprops run fast and smooth, while providing excellent cornering characteristics. You'll also find outstanding acceleration and quick on-plane times with these new props. Comprops are made of a high-tech composite that resists leading edge dings common to aluminum propellers. If you have a high speed prop strike, the Comprop blades are designed to break and absorb much of the shock, reducing costly drive train repairs. (It costs much less to replace a Comprop than a lower unit.) At prices up to 40% lower than aluminum props and up to 80% less than stainless steel, Comprop simply can't be beat for low cost and high performance. Boats and applications vary widely. When replacing a propeller use one of similar size and pitch to achieve similar performance. IMPORTANT NOTICE: If application is more than 225 shaft hp or boat is more than 21' long or 3,000 lbs. in weight, then a Comprop is recom-mended at reduced power only. 13 tooth, 4" hub. Note: This prop will only fit the 4" gear case E-Tec motor.
