Hi Ian,

I've been looking for something exactly like the
pump in your post. In an emergency, it seems
silly to have a 27HP diesel motor with 70+ gallons
of fuel sitting by doing nothing while the boat
sinks.

Of course, its going to take a little more than
the average bilge pump hose and through hole to
handle that sucker when it starts pumping.
Something like the 2" diameter hose that handles
my engine exhaust.

Before seeing that article, I'd considered slaving
a hydraulic pump to the front of the diesel, and
powering a trash pump with a hydraulic motor. Of
course, the hydraulic pump does give you some more
options as well, such as powering a scuba
compressor, or 110V AC generator with hydraulic
motors as well as powering an emergency pump.
I'll have to think about that some more.

Its engine driven and clamps round your prop shaft, acting as a bilge
blower (or rather sucker) untill the water gets up to its intake :-)
