Glen,
I run mine to a deck fitting from which I can use a number of hoses and
nozzles, but I also have a ball valved sea water feed to the mud box. So, in
my case, I can also use this pump for a utility sea water pump. In my
application, the mud box is serviced by a big 2" Jabsco driven from the
generator. Although our applications are different, the deck outlet with a
cap on deck is a neat, clean and maintenance free solution. In an emergency
situation, soiling the deck area, would not be your most pressing thought
nor would outlet submergence.

Looking for thoughts on the following problem.

I have got two bilge pumps for the main bilge on Rutu. A little 5 gpm
Jabsco diaphragm pump on a strum box to take care of minor accumulations
and a Rule 3700 for the Oh, %&$@* ! situations. My problem is how to run
the hose for the 3700. The basic rule is that the through hull should
always be above the water line but that would mean out the transom. The
dynamic head for 25' of hose back to the transom is a lot more than a
short run through a vented loop to a through hull at the waterline on the
side even including the loss from a check valve.

The side outlet would have less head and much less back flow but the
through hull would be under water when the boat is heeled. Any
suggestions?
