Recently Pro Power Ski has created a new product out of necessity for all personal watercraft. Stock bilge systems can not remove water fast enough after rollovers, subbing or freestyle maneuvers, ect.
Electric bilge pumps kits can be expensive, difficult to install and often fail.
Some models may require drilling through the hull and mounting a drain fitting first. The one way rubber flapper valve basically acts as a bilge by removing water from the watercraft through gravitational force. As the watercraft accelerates forward any water in the hull is forced out of the fitting on the rear of the craft. A must for any racer or freestylist. Pro Power Ski provides kits for models with and without drain holes.
