Bought a 3700 gph Rule pump for the Tolman just in case I take a lot
of water. My normal bilge pump is a 750 gph one. I intend to find
some smooth bore hose for it and some oversized wire to power it.
Downside is, it was expensive and I will probably never use it. Might
even get a dedicated battery for it.


I was looking at a sailing magazine a couple of months ago. I saw an article
about someone connecting a hose to the water pump, then using the engine to
suck water out of the boat. Seems like that would cut out a lot of the
battery problems because it would engine not battery doing the work.

Caveat: If the pump sucks all the water out and burns up, you have lost
the use of your engine. The bypass valve must be manned constantly to
avoid that calamity.
