Shurflo by Pentair PRO BAITMASTER™ II Livewell Pump - 12 VDC - 4.0 GPM

The Shurflo by Pentair PRO BAITMASTER II Livewell Pump is a 12 VDC, 4.0 GPM heavy-duty marine pump engineered for live-well and washdown applications in demanding saltwater and freshwater environments. Designed as a direct 4901 replacement, this self-priming pump delivers consistent water circulation to keep live bait oxygenated and healthy throughout extended fishing trips, whether you're running a weekend bass tournament or an offshore saltwater charter.

At 4.0 GPM output, the PRO BAITMASTER II is optimized for bait tanks up to 35 gallons, delivering adequate flow without overwhelming small to mid-sized livewells. The pump features a seamless motor shell and sealed switch design that protects internal components from splashed saltwater, spray, and humidity—critical for survival in corrosive marine environments. Thermal and ignition protection safeguard against overheating and electrical hazards, while the self-priming capability eliminates the need for manual priming and allows the pump to run dry without damage, a significant practical advantage during tank refills or maintenance intervals.

This pump serves both casual anglers maintaining small recreational livewells and serious tournament competitors who depend on reliable bait circulation for competitive advantage. The 12-volt DC design integrates seamlessly with standard boat electrical systems, requiring no special wiring modifications. Compact dimensions and reasonable weight make installation straightforward on vessels ranging from center consoles to bass boats. The PRO BAITMASTER II's proven reliability record makes it the go-to choice when replacing aging or failed livewell pumps, ensuring your bait stays fresh and your fishing day stays productive.
