What is a washdown pump on a boat?

A washdown pump system is exactly what it sounds like: a water supply and a pump. The pump draws in external seawater (or raw water) via a thru-hull and pumps it up above deck, where a hose is connected to clean off your boat after every use.

How many amps does a washdown pump draw?

A washdown pump can draw 10 amps or more, which can dangerously overload a lighting circuit. The safest course is a dedicated circuit with a new fuse or breaker in the main electrical panel.

How do you install a raw water washdown?

Locate and mount the washdown pump in a dry location in the bilge up to six feet from the raw-water intake, but be sure to allow sufficient room to place the raw-water strainer on the inlet side of the pump. For extra-quiet operation, insert a 1/8- to ¼-inch rubber gasket between the pump and the bulkhead.

How does a seacock work?

A seacock is a valve on the hull of a boat or a ship, permitting water to flow into the vessel, such as for cooling an engine or for a salt water faucet; or out of the boat, such as for a sink drain or a toilet. Seacocks are often a Kingston valve.

What is the difference between a seacock and a ball valve?

Ball Valves operate with a quarter turn similar to a seacock, but are not designed to be attached directly to a thru-hull fitting. Most ball valves feature NPT (tapered) threads on both ends and are compatible only with tapered pipe fittings.

Should a seacock be open or closed?

What is not in doubt is that all seacocks below the waterline should definitely be closed when the boat is unattended for anything other than short periods. Cockpit drains shouls always be open of course.

Raw-water pump This pump does the bulk of the engine’s cooling. It draws raw water (this may be seawater, fresh water or whatever mixture of the two the boat is floating in) into the engine’s open or raw-water cooling circuit using a rubber impeller. The impeller and its weaknesses are well understood.

Should hulls be bonded?

Yes any medal through hulls need to be grounded to the boats bonding system. I.ve always “green wire” bonded mine to a dedicated bonding zinc located below the waterline.

When should I replace my hulls?

You can check the thru hulls first when scraping the paint from the metal and if it looks golden and not pink, it is in good shape. If the metal is pink, the thru hull fitting should be replaced immediately, since the metal has no strength and is ready to fail.
