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? Been Schooled Bob 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. |

No ****, during a torrential downpour earlier this year I cleared a good three feet of water from the well of our basement stairway in what must've been RECORD time. Five gallons at a time and facing water damage to a lot of furniture really motivates you to BAIL FAST. But in most boats you've got nowhere near the room needed to get good clearance to scoop and get it out of the vessel quickly enough. |

down. Now that's funny! I believe I recall reading a test of pumps in a British sailing mag (PBO?) where this was disproved. Not even close in fact, compared to a good pump. |

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. Don W.

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 :-) 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. -- Roger Long "Bill Kearney" wrote in message t...

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. Brian Whatcott Altus OK |

: Centrifugal impellors can take plenty of abuse, and absorb lots of power. One of my friends likes to bid on government surplus junk. One of the surplus flyers he gets had a "portable fire pump" in nearly new, operable condition for bid. He didn't bother with the fine print, thinking it was a "Handy Billy" or one of the Navy's sailor-carried portable pumps that might be handy around the place. They called him from the Supply Center and asked him to come pick up his pump. So, he took his truck down and nearly couldn't bring it home! It was a portable pump, allright. With a 4-wheel trailer! There was a 8V92 Detroit Diesel Two-stroker hooked to this gawd-awful-big pump that fed a firehose manifold with EIGHT outlets of various sizes. It also came with 4 firehoses and a huge suction hose with big screen filter on the bottom to throw into the lake. It even had diesel fuel in the tank and had just been serviced. We took it to the lake boat landing just to see if it worked.....(c; His whole neighborhood could be in flames and he'd have it put out in just a couple of minutes....(c; He paid $800. The next bidder bid $400 and that was all. Some fire department in Ohio called him to ask if he'd sell it to them for $5000. After a bit of dickering, he got $8K for it....not bad for one trip to the base. Make a helluva bilge pump....or JET DRIVE! -- There's amazing intelligence in the Universe. You can tell because none of them ever called Earth. |

If you're screwed, you're screwed. Powered or not. Not at all (speaking as a long time researcher of marine accidents, currently, the Titanic). Running aground to avoid sinking and buy time to control flooding is a time honored technique that has saved many vessels. When a vessel becomes severely flooded, loss of stability and capsize become a primary danger. The ability to control attitude in seas to diminish the probability of capsize can be a life or death issue. No argument there. But then nor does it have the constant horsepower drain that pump incurs. The beauty of that system is the very low horsepower drain. When functioning as a blower, the loss would be insignificant. It isn't going to be a very effective blower at shaft rpm speeds but it should keep a constant, very low, flow going. -- Roger Long |

But if flooding of a major nature is happening, a pump that can keep up with it is more important than moving, otherwise movement will have a decidedly downward trend. |
