Collection: Bilge Pumps

Keeping the bilge dry requires matching a pump to your boat's size, voltage system, and whether you need hands-off automatic operation. Rule, Attwood, and Johnson Pump offer fixed submersible models ranging from compact 200 GPH portables up to high-capacity 3700 GPH pumps. Both Rule and Attwood produce 12V and 24V versions, and Rule also offers an 1800 GPH 110V model for boats with shore power access. T-H Marine rounds out the category with float switches and enclosed pump switch housings that complete a fully automatic bilge system.

Before buying, estimate the GPH capacity your hull demands, then confirm your onboard voltage, since 12V and 24V models are not interchangeable. Non-automatic pumps run only when switched on manually, while pairing a pump with a float switch from Attwood or T-H Marine gives you automatic protection without constant monitoring. Attwood's portable WaterBuster suits cockpit puddles or small inflatables, while heavy-duty 2000-series fixed pumps from Attwood fit permanent below-deck installations. Rule and Attwood both sell replacement motor cartridges for several models, so a well-chosen pump can often be serviced rather than replaced outright.
