a Big Pump
 

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.

Make sure you put that battery in the lowest part of your boat.

Wow, to me that's a bit of overkill, but if need be uyou could
probably use it for jet propulsion if necessary.

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.

I think that's a good plan, with a couple of caveats: It's a good
idea to derate the capacity of bilge pumps by 50% or so to compensate
for head loss and hose friction. It's also important to remember that
bilge pump float-switches have a proven record of unreliability,
leading to the need for a manual override switch, and possibly the
desirability of a second, totally separate, pump/float-switch combo.

No one has ever complained about having too much bilge pump capacity.
If the cockpit of an open boat swamps with big water you are only
seconds from a loss of stability and capsize.

You should only have to match the wire guage of the leads on your pump
for your wiring.

I will probably go up one wire guage due to the long run from the
battery that will be on the floor of the bow. My reason for getting
this pump is reading David Pascoes advice on the topic.

When you think about it, that's really only a gallon/second.

Yes, and the reality is more like half of that.
