Re: Inability to keep the water out > Long distance rescue
I apologies before posting, as I'm sure I'll upset someone, but this is quite a funny stream with some of the suggestions. I think you would need to get a bigger boat to carry everything.
I have one suggestion if the need to remove this amount of water becomes necessary, 'insurance', and make sure it's paid up.
Seriously, the best Manuel pump is a good quality manual bilge pump. You can get them that move close to 120 ltrs a minute (30 gal for you yanks). That's massive. If it's coming in so fast that one of these won't keep up to the job, you really need to concentrate on getting ready for leaving the boat.

Standard 3" crash pump does 600l per minute. And leaves you free to deal with stopping the water ingress.
Kodiak 3" High Output Trash Pump with Honda GX240 OHV Engine | Engine Powered Pumps
Up to 1800l per minute if you go to a transfer pump. That's 476 gallons per minute!

I don't know who Manuel is, but he's going to have a hard time keeping up with a manual pump!

Re: Inability to keep the water out > Long distance rescue
A pump powered by an outboard is a great idea. Not at all wacky except not available. Small, light, and extremely capable if done correctly. Would not take up much space at all. But I can asssure you it won't be me doing the build. Happy to assist with the project but no interest in bringing anything like this to market.
You could have three swivel wing nut bolts and an attached flat collapsible
hose. Pull the OB cord and you're pumping huge amounts of water which until you run out of gas will allow you to fix the leak and/or wait for rescue.
Cooling either a clamshell or even a big enough housing to have the inlet cover the ob pump intake.

Re: Inability to keep the water out > Long distance rescue
Be interesting to see how much water it would really shift. Can see the typical 8hp egg beater being a whole lot of use. Not to mention securing the thing while it pumped. Then there is the issue of debris in the water

Having worked in mining camps in the South American jungles with pumps and diesels I can tell you it will work. In thoses environments gum wrappers and used. Milk jugs cut into pieces for hose clamps and gaskets etc. It can take weeks to hand carry equipment up treacherous slippery trails and supplies are gold. These miners are creative to a fault.
But yeah you're not gonna go to West Marine and pick one up with a credit card and have a pimply faced "Marine Tech" hhok it up for you with a guarantee.
This stuff is fun not work. But If you have a nice boat I'll bet mine against yours I can make one out of crap and it'll work great.

The above 1800l per minute crash pump runs on an 8 HP motor. Most cruisers I know have 15 HP outboards (or bigger). These pumps use impellers or diaphragms dramatically smaller than an outboard prop, if that's what you're pumping with. Bet you could use the same pump model the crash pump does, but run by an outboard, if you are going for shaft driven. Says it will handle debris 1" in diameter.

I'm a KISS guy. 4300 GPH, (that's about 80, 55 gal drums!) almost no fuel usage, $500, smaller than a 5 gal bucket. 1.5" hoses.

Re: Inability to keep the water out > Long distance rescue
I do think those of you talking about these big fire fighting pumps are all missing the point a little. Which Dave, (Goboatingnow) was alluding too. If your going to aim for all these larger, motor driven pumps and pumps off your engine and all that sort of thing, you got to question whether you need a bigger boat to put it all on, or a helicopter to deliver it to you when you need it.
A large 'manual' (I was careful for you Dave :-) ) pump is everyone's friend which is why it's mandatory on all official cruising/racing boats.

Several of us already have larger boats with plenty of capacity, ie not a catamaran. Mine has three large Manuel pumps. But no Manuel's to man them. Therefore, I pursue other options as well. Never too many tools in your tool bag.

Hmmmm ..... I thought KISS stood for simple. I'm not sure an exploded parts diagram of that pump would mark it down as being from the simple end of the spectrum of contenders; I'd have thought that was reserved for buckets, and Edsons...
But I guess you could point out that an exploded view of a human makes a Honda pump look simple. And buckets and Edsons don't work without a prime mover.
To which (scratching head and conceding the point for a moment)
Ah.... yer: but the human was there anyway, and so is the diesel prime mover (and for those who like'em, the outboard)
Isn't it better to use resources which are already to hand, if you can?
