The SE Sport 400 is the easiest hydrofoil to install ever, requiring no drilling of holes in your engine’s cavitation plate. It mounts in about five minutes, requiring one wrench or socket and a Phillips screwdriver. SE Sport 400 brings the same performance boost for your boat as the SE Sport 300, but doesn’t need the Sport Clip, used for no-drilling attachment of the SE Sport 300. SE Sport 400 is recommended for outboards and sterndrives (including Volvo) from 40 to 350hp.
