The SE Sport 400 Hydrofoil has a compact design that produces less resistance, improved thrust and greater top-end speed. The crescent-shaped planing surface promotes ultrafast hole shots while practically eliminating porpoising. The Sport 400 also keeps your boat on plane at lower speeds for better gas mileage and a smoother ride while towing a skier or tube. SE Sport 400 fits most outboards and stern drives 40hp and up. It doesnt require the Sport Clip for a no-drill installation. Exclusive sight gauge included for a perfect installation. Colors: Black, Gray (not shown). Type: Hydrofoil Replacement Hardware.
