Cwcarter, looks good and neat, just trying to work through all the fittings especially through hull fittings as I only want to drill one hole if possible to accommodate both a live bait pump and a deck wash.
Definitely possible. Might just require a bit more imagination with your plumbing or choice of the right pumps with incorporated take offs. Make sure you add in a ball valve in your input. Really useful when your cheap a#$e pump housing decides to crack and let the ocean in - don't ask. Not happy Jan. The only issue you may have is if you provide a path via the input where a pump can suck air through the other pump rather than waterOriginally Posted by Dignity
Depending on how much you want to spend, a good dual purpose pump is the SHURFLO BAIT SENTRY 800GPH 12V
They are also available in a 1100GPH
That is one I have used before on my BIL's old rig that does have a secondary input to connect your wash down pump to. It's not a dual purpose (pressure) pump but does allow one skin fitting to feed both pumps easily. There are some comments on the net about how loud this pump is but personally I don't recall any hideous amount of noise when using it. I don't think they are a self priming unit - we mounted it directly onto the ball valve that was attached to the inside of the through hull scoop / strainer.
Are the shurflo's below waterline?
I have only the one inlet under the boat with the pipe ending up above water line. I was worried the suction pumps might suck air from each other but they don't.
I think I need to do a "circuit diagram" for what I want, not sure about the facts still.
Sorry Dignity Heres the link

The Bait Sentry series with the "magnetic clutch" is. Other series may or may not be.

I think I need to get out of retirement and go back to uni to figure all this out especially if I add the deck wash into the equation. I remember when we used to fish the Toyota comp on Fraser and we had to keep our catch live all night we had a drum on the back of the truck and we constantly drained the bottom layer of water to get rid of the dirty water and ammonia etc.
Scottar, after a good night's sleep I have reread the shurflo pdf and it is interesting that the pump impeller must be below the waterline. I have an Allison Vision, it has a pod and duck boards and I was hoping to Install a pump on the duck board with the scoop through it, this places the impeller above the water line, was planning on something like this

other issue I now realize is a second hole will be required for the waste discharge, how could I have forgotten that.
Maybe I just need to sell this one and buy another boat with all the bells and whistles.
That one is below water line as well. You want a self priming diaphragm pump above water.
Are any deck wash pumps made all or predominantly out of plastic yet? For all the ones I've installed, the amount of work they actually get before they rust out is horrendous.
Democracy: Simply a system that allows the 51% to steal from the other 49%.
Just something I have been thinking of and it's not perfect but using a bilge pump on a bracket over the side of the boat and plug it in (to power) when I need it.
IMHO the pressure type pumps are able to draw a bit of head. Not sure how much but in the boat situation, you'll be fine.
