Okay, ya got me on that one...............

How about Model number "3000 gph." Athough gallions per day might be
closer.

You got good eyes!

but dont I get points for the 2" trash pump for the time when I
actually need a pump?? Or maybe place a salvors lien on somebodies
boat?

PS Oh, and Brian thanks again for the MS strength info. I descided to
go with a 5/16" MS. I did not realize that a 1/4" 316 MS had such a low
SWL.

Very, very manly, I'd say. (I even caught myself thinking along those
lines at a [ gasp! ] Harbor Freight store where they were showing a
semi-trash pump that looked pretty mean) :-)

How about upwards of 900 gpm (yes I do mean over 50000 gph)?

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 :-)

This has got to be right at the top of my "Damn, I wish I'd thought of
that - ten coolest boat equipment ideas" for the last few years.

I wish I had more than 7/8" between my coupling and my stuffing box

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.

If you're really screwed then shut off the seacock and cut the raw water
intake hose to the engine. Use that to pull water from the bilge, through
the engine and out the exhaust manifold.

Then a little bit of something floating around in the bilge goes into
you pump impeller and you have an unpowered sinking boat instead of a
powered sinking one. Great.

Besides, a raw water pump doesn't have a fraction the capacity of this
rig.

No argument there. But then nor does it have the constant horsepower drain
that pump incurs.

Oh yes! Reminds me of that scrap yard builders series on TV:
the objective was to build a fire boat capable of dousing a flaming
building on the far side of a lake.
One team decided to use water jet propulsion as well as for dousing
the flames. They started with a brake drum, and welded on three vanes
for the impeller, and cased it to a hose.
Centrifugal impellors can take plenty of abuse, and absorb lots of
power.
