Keep your water systems flowing

Pumps run all over a boat, and Johnson Pump is a trusted name across the range. The line covers bilge pumps and float switches that keep the hull dry, washdown pumps for rinsing the deck and anchor, circulation and engine cooling pumps, impellers, and livewell aerators.

Choosing the right pump comes down to the job and your system. Size a bilge pump to your hull and pair it with a float switch for automatic operation. Match a washdown pump to the pressure you want and an impeller exactly to your engine, since impellers are specific. Confirm voltage and port sizes fit your plumbing. Keep a spare impeller aboard, since they wear. Review the product details and your system specs before buying. With Johnson Pump gear, you keep your boat's water systems running reliably.

Frequently Asked Questions

How do I size a bilge pump?

Size the bilge pump to your hull and the volume of water it must clear, with margin for safety, and pair it with a float switch for automatic operation. Confirm voltage and port sizes. Check the product details for the pump's flow rating.

How do I find the right impeller?

Impellers are specific to the pump and engine, so match the impeller exactly to your engine and cooling pump by part number. Confirm fitment before buying, and keep a spare aboard, since impellers wear and a failure stops engine cooling.

What is a washdown pump for?

A washdown pump supplies pressurized water to rinse the deck, anchor, and gear, often drawing from a thru-hull or freshwater tank. Size it to the pressure and flow you want, and confirm voltage and fittings match your system.
