This WOW Heavy Duty Y-Harness with EZ-Connect System is designed for use on boats that have an outboard motor with no pylon or ski eye. The hooks are clipped on each side of the boat and then you connect up to a 4K tow rope (sold separately) to the EZ-Connect System. This tow harness is perfect for pulling a variety of watersports activities or 1-4 rider tubes. A 6-inch float keeps the attachment loop floating on top, away from your propeller. It is 16-feet long to fit larger boats & pontoons.
