Shurflo Pro Baitmaster II 12V 4.0 GPM Livewell Pump

The Shurflo Pro Baitmaster II 12V 4.0 GPM Livewell Pump is built to move water efficiently for livewell, baitwell, or aeration service on compatible boats. Its marine pump construction supports the repeated water-transfer cycles these systems require while keeping the installation compact enough for crowded machinery and plumbing spaces.

The pump is designed around dependable marine water movement, with features appropriate to its model such as self-priming operation, durable inlet construction, or serviceable pumping components. Correct hose sizing and an unrestricted water supply are important for maintaining useful circulation.

Confirm electrical supply, circuit protection, hose sizes, intake arrangement, tank capacity, mounting position, and service access before installation. Keep intake plumbing clear, avoid unnecessary restrictions, and test the complete system for leaks and reliable flow before relying on it for ballast, bait, or livewell operation.
