System 1 uses our V1 Drain Shut-off valve which is cable operated to open and close the livewell drain hose. Filling of the livewell is usually accomplished by a centrifugal aerator pump (500 to 750 GPH) mounted through the transom or pad area below the water line. A screw-on stainless steel strainer screen is used to protect the pump impeller. The aerator head used with the fill pump must be mounted above the livewell water line to prevent water loss when the pump is off.To prevent overfilling of the livewell, an overflow must be installed. The recommended overflow uses 1-1/8" inside diameter hose with the livewell fitting installed in a wall of the livewell with the top of the fitting located at the desired livewell water line. The exit through-hull fitting is usually mounted through the transom or pad area of the boat below water line for efficient and silent operation.Recirculation of livewell water requires a separate livewell mounted pump and second aerator head. The aerator head on the recirculation system can be any of our venturi type aerators including our Pump-out Aerator which will further enhance the system and allow the same recirculation pump to be used to pump-out the livewell. A pump of 700 GPH or more is recommended.

OPERATION

Off-Plane
While off-plane, the livewell can be filled by placing the drain control valve in the "CLOSED" position and turning on the fill pump. To empty the livewell, the fill pump is turned off and the drain control valve is placed in the "OPEN" position. Note that when off-plane, the livewell will only drain to the level of the outside water until the boat is placed on plane or placed on the trailer. With our Pump-out Aerator described above, water can be pumped out at any time both on and off-plane.

On-Plane
While on-plane, the drain control valve will prevent livewell water loss when in the "CLOSED" position or allow water to be drained when in the "OPEN" position. Recirculation and aeration can only be accomplished with a separate livewell mounted recirculation pump as shown above.
