Outboard, Stern Drive Engine
Great question! While DELTA works well on almost all single-engine watercraft, it's not recommended to surf traditional outboard and stern-drive boats for safety reasons.
In wakeboarding or water skiing, the boarder/skier is typically 25-30 ft from the prop, whereas in wakesurfing the surfer is about 6-8 ft from the prop. This puts the surfer too close to the propeller, so we do not recommend surfing behind an outboard or stern drive boat.
