I carry a sump pump that I bought in a hardware store as an emergency pump.
It's 110v but I have a generator so unless the generator is dead I can use
it.
I checked out the pumps at Home Depot and Lowes thinking the same thing.
About $135 gets you a pump with a handle on the top 1 1/2" or even 2"
outlet. Then I checked West Marine and was surprised to see a 6000 GPH DC
pump with a 2" outlet for about the same price. The DC pump is shorter,
enough that it would fit under my floor panels without having to cut an
access hole.
The pros and cons as I see 'em:
DC pro: neater install, same cost, same capacity,
DC con: less effective run time as compared to inverter run AC because
inverter will give me 120VAC right down to 10VDC while at 10VDC the DC pump
is not doing much.
AC pro: not permanent unless hardwired in, Can use in emergency anywhere AC
outlet or on extension cord
AC con: larger, heavier
Please add to the list....

I also carry a 110volt sump pump but it has another purpose. In the
Chesapeake there are some summers that the sea nettles are so bad in
certain areas that they clog up strainers every 15 minutes. I cheap easy
work around is to take a 5 gallon bucket and drill 1/4" holes every inch or
so all over the sides and bottom. Then suspend the bucket over the side on
a light line so the top is a couple of inches out of the water. Then with
another line suspend the sump pump inside the bucket so it sits a couple of
inches off the bottom.
Then a hose from the sump pump through a hose fitting in the side of the
boat to feed the a/c units with cooling water. You can run the hose through
the window but a hose fitting looks a lot nicer. Just disconnect the juice
to the a/c pump and unhook the outbut hose from the pump and hook it to the
hose from the bucket. Each of the many holes in the bucket allows a small
amount of water to enter and the nettles just come right to the bucket but
there is not enough turbulence to suck them in.
I have only had to use the bucket three times in 10 years but each time it
was so hot that you did not want to do without A/C and going down into a
hot bilge to clean the strainer was getting old. Obviously it doesn't work
underway but is fine at anchor or at a marina. For storage the pump, hose,
extension cord all store in the bucket and it is ready to go whenever you
need it and of course you have a back up pump for the a/c or any dewatering
job.

My sump pump cost about $87.00 CDN (which is peanuts $US) and is permenantly
installed. It comes complete wt a float switch so I won't have to be around
to activate it in case of emergency.

I tryed to install one of those not too long ago, had to return it. Seems
the hose (run) was so long that each time the switch turned to pump off,
the water in the hose came back down and turned the pump back on. Ended up
install one of those "computer controlled" types. Works fine...jd

I had the same problem till I installed the one way valve that is sold for
these pumps. I suppose the water eventually seeps back in but it seems to
work.
