Marine Pumps

Pumps are an essential part of your onboard plumbing system. We’ve created this helpful resource to help you find and select the right pump for your application.

Pressurized Freshwater Systems

Freshwater pumps deliver water to fixtures onboard a boat. Pressurized water systems make life aboard more comfortable by providing water "on tap" for dishwashing, showers and other applications. The complexity of installing and maintaining one will depend on the number of outlets and accessories you choose.


Choosing & Installing a Washdown System

An onboard washdown system provides a convenient means to hose down the deck after a day of boating. Clean up your cockpit after landing a big fish, rinse off the muddy anchor rode as it’s raised by your windlass, or hose off seagull indiscretions and rinse the decks after a scrubdown.


Selecting a Bilge Pump

Virtually all boats end up with unwanted water in the bilge, which must be removed. Water gets in from a propeller shaft packing gland, a leaky portlight, leaky seams in a wood boat, melting ice from the icebox and a multitude of other sources.


Choosing a Pump

There are four general pump designs, each with specific characteristics, strengths and weaknesses. Which one is right for you, depends on your application.
