danbouck Posted September 12, 2010 Report Share Posted September 12, 2010 My boat is making the move from the dock into the boathouse this weekend for the fall. But I would like to spray out the boathouse to clean it up first. I was thinking of hooking a hose up to an old bilge pump and spraying it out that way. Will a bilge pump be able to handle that? I think it's a 400gph pump Link to comment Share on other sites More sharing options...

I think it's a 400gph pump humm thats only 6.5 gallons per minute. made if you put a reducer on the hose where the water exits, it may up the pressure enough.

aplumma Posted September 12, 2010 Report Share Posted September 12, 2010 If you are intending to use a 12 volt bilge pump rated at 400 gpm it will not have any head pressure. The pump is a centrifugal pump that is spaced for volume not pressure to test this just put your finger over the outlet and see how easy it is to stop the flow. Their are 12 volt pumps that will work look for a wash down pump they are designed for pressure not volume. Link to comment Share on other sites More sharing options...

HTHM Posted September 13, 2010 Report Share Posted September 13, 2010 A gas powered pressure washer might be the way to go, or a gas powered pump. Link to comment Share on other sites More sharing options...

Good answer with a short 6 ft hose that has a screen on the end to keep out chunks it should be able to pull from a water source. Art Link to comment Share on other sites More sharing options...
