The problem with with all these cheap wash down pumps (ie shurflo, et al.) is they they run on a pressure sensitive switch. And they can cycle like hell because they have no volume to work off of, you call for demand and the pressure drops instantly.... This is what kills them. I use my wash down a lot and would burn them out every couple years. Last year I put an accumulator in the line and it really seems to help a lot. Nice smooth high pressure and the pump is either on or off, when it charges the accumulator, not onoffonoffonooffonoff... I like it so much I bought a second one for the FW side, the wife likes the house like pressure at the sink and shower head now without the cycling.

A bait well pump is a different kind of pump. You don't want the pressure sensitive feature and you want more of a continuous duty higher volume low pressure type pump. If you get a cheap one of these they will burn out just when you need it. (Hard core live bait guys have a second back up pump already plumbed and when the primary pump burns out you can valve in the backup) You really don't need to hang a pipe over the side, if you have a thru hull fitting the pressure thru that underway is plenty to fill your well but the problem comes when you stop and anchor up for a few hours.

Freak...how did you attach the pipe to the boat...via the trim tab or screw into the hull with a bracket of some kind?
