I apologize if this question has been covered previously, but how important is it to have a manually operated (hand) bilge pump as a backup in case of battery failure? If a good idea - any suggestions?

Thanks
 
Keep a big bucket aboard. The best manual bilge pump is a frightened man with a bucket. C-Otter
 
This beast will get the water out pretty well...and it's ready for immediate use. Works great...and I'm glad we have it. Intake is at the transom near the plug and there is an inline check valve to make it self priming. She spits water within a few pumps.

Nice to see another with a "gusher" type pump. I don't even have an electric - just as well because electric ones seem to be a constant source of problems, failures and many inquiries on this site. I have a Whale Gusher pump installed with the strum box in the well by the drain plug. I have used it once or twice in four years to suck out a pint or so of accumulated rainwater. I think a manual pump is as important as a radar reflector.
 
I have two electrics that are fix mounted + a spare electric with 25' of cord on a 12V cigarette lighter connector (can be powered from another boat) and a manual pump ofthis type (I have the 10GPM one). I like this style as you can move it around to pump out a wet spot, move it over to another boat or dinghy in need or use it as a crude raw water wash down. I use mine a lot to rinse out the port lazarette which I have set up as a fish box. Not only is a manual bilge pump handy, a manually operated self bailing device is required in Canada.

Is the handle removable? It would a great fish whacker!

How is unit installed? just 4 screws?
 
I keep one of the long 2" tube type of bilge pumps aboard--mostly for inflatble, as well as the two portable and 2 built in bilge pumps. The Whale gusher pumps are very good. We had the double chamber diaphragm 1 gallon a stroke: 60 gallons a minute in our cruising boats. Had to use it in a major Atlantic storm, since the electric pumps were getting plugged upwith dog hair, sawdust and construction debris.
 
After a very sad friend woke me one morning with a bildge full of water, and
no one on the entire raftup had a manual pump, I bought one of the tube
type with a long hose.

I have the little bildge area in the dinette, and I can put the tube down
into the area, and have someone hold the hose over the side of the boat and
completely pump out the CD-22. Since the electric pump is currently
broken, this is a good thing.

The tube pumps are nice because they can be quickly taken apart and
cleaned if they suck up something that prevents the vacuum from building.

Many thanks for all the feedback.

It looks like at a minimum we should get a 'tube' bilge pump which look fairly inexpensive. If we end up spending more time in rougher seas - one of the other more robust types may be in order!

60 gallons a minute is a lot of water for a 12 volt pump, much less a hand pump. 3600 gallons per hour, or more than three times the volume of water my bilge pump is capable of.

A person would have to be in a sinking boat to have the staying power to pump that amount of water.

The largest pump they make is rated for 31 gals per minute. A little less than Bob remembers but still a big number (1860 gal per hour).
 
The whale handpumps are great, plus with the correct end fitting they can get out most of that little bit that is left in the sump, something most of the automatic electrics won't. When I move up to a bigger boat I will have one. I always had one in the sailboats.

Some sites/dealers claim 42 gpm for the WHA BP3000 model and others claim 31 gpm.

Don’t know which is correct but either way, it is a lot of water. They seem to be priced in the 500 to 600 dollar range .

Actually the pump we had was larger than the Gusher 30 (apparently not made currently)--it was also a double action pump (chamber/two diaphragms) which put out one gallon a stroke back and forth stroke I can assure you that in the middle of the Atlantic Ocean in 40+ foot seas and 70 knot winds, one can move one heck of a lot of water with manual pump!
 
Our pump says Bosworth on the handle. It was throughbolted by the original owner. I don't know the rate of flow but it will empty a 5 gallon bucket pretty darn quick.

Yep...not the way I would have done it, but it was there when I bought the boat. I pulled it off, though, and made sure everything was well sealed.
