If water, an ordinary bilge pump should do just fine.


Actually, when boats do sink it is often because their
pumping capacity can't keep up with the new hole long
enough for the crew to find and plug it. I've read
several stories of cruising boats sinking that started
with an unknown thump etc. and the floorboards were
quickly awash while the crew searched for the problem.

Having watched a 5HP waste pump empty a flooded basement
in just over an hour (was working on a basement crew,
and the hole we were to work in had flooded to the top
due to an overnight thunderstorm) I've been impressed
by the sight of a 3" hose running at full capacity under
the influence of that little gasoline powered pump.

Sure would be nice to have a big pump like that in the
engine space slaved to that nice big diesel propulsion
motor.

I read somewhere about some german engineer who had his
cruising boat rigged with two of them.

I am in construction and have spent a lot of time over the years trying
to get recalcitrant one cylinder motors to start, whether they be on a
trash pump, a chain saw, a compressor or the like. I have also read a
lot of stories about Coast guard pumps not starting after they are
dropped on board.

This past November I was onboard a boat that hit a ledge in Woods Hole,
MA and I can tell you it is sobering to see how ineffectual standard
bilge pumps are.

The TowBoat US boat that eventually took over from the Coasties put a
pair of these on board:

I had never seen one before, but plan to buy one. I think the odds of it
starting when/if needed are much better than a small gas engine pump.
