Figured I would revive this old thread instead of starting a new one.
Pretty much the same question. I would like to install a washdown pump on our boat. In 3 years, the only reason I can see to use it is to clean the bird poop off (although I can see other uses down the line). Seems like every 2-3 trips down to the boat, there is more poop on it..and it is a PITA with the bucket/rope and hours (or so it seems) of cleaning
. I just want to be able to hook a garden hose up to it when I need to use it.
Any reason not to share the through hull
with the water intake for the motor
(above it is mentioned NOT to, but no reason given). I would assume properly installed and valved off, it should be safe. I like it for a clean, elegant install. I was going to T off it and valve it before the pump.
I could go with the throw a section of hose over the side and suck the water up, but would the washdown pump have enough oooph to suck water up over the gunnel if it isn't primed and to the pump without wearing it out? This would be safest (no cutting/valving of water intake) for the boat, but not sure if it is the best choice. Less elegant, but safer, if the pump can prime itself
