Sea Water Wash Down - 2007 Grady 360 Express

[Cmaki]

My sea water wash down hose is not pumping water. New boat to me and need direction on where to either turn on pump or begin troubleshooting. Thanks in advance.

FIrst is to open the seacock for the washdown. Second is to hit the washdown switch. Not sure where either are located on the 360, but in my 330, the seacock is under the midberth.

If it still does not work, it's time to find the pump and break out a multimeter.

Download owners manual from GW site. It will show you where the thru hull is, where the pump is and wiring diagram.

Washdown pump has a microswitch inside and they frequently fail. Amazon item. Same switch used in most Shurflo pressure pumps.

As Kirk mentioned, make sure the seacock is open first. Last weekend I had a brain fart while out fishing, flipped the wash down switch on and had nothing. I figured the worst and thought the pump went out, then I remembered I'd forgotten to open the seacock. Crisis averted lol.
