800 GPH Livewell Pump. 12V DC. Straight Seacock Inlet, 3/4" NPT. High Inlet Pressure for High-Speed Vessels. Push-Twist Motor Cartridge Replacement. Anti-Airlock. Secondary Washdown Port.

Built on over 50 years of Rule marine pump heritage, the Rule 603FC livewell pump delivers 800 GPH at 12V DC through a straight seacock inlet (3/4" NPT). Engineered to handle the high inlet pressures of high-speed water intake scoops — where standard livewell pumps fail. The push-and-twist motor cartridge system allows one-hand motor removal and replacement even in hard-to-reach installations. Anti-airlock protection and a secondary washdown port are standard.
