Electric Bilge Pump?

I have a 4.6 Avon Typhoon. As I have had two shoulder surgeries and find the manual bilge pump straining on my shoulders I am toying with the idea of putting in an electric bilge pump. I see attaching it to the transom below the rear floor board. I would then mount a battery to the transom above the floor board. Any thoughts on whether this would work or otherwise be ill-advised.
Thanks, Dennis

Can't see why it wouldn't work, a trunk would work also though.

Don't know how your boat is laid out, but it should work. I assume you have no battery on-board now? You'll also have to figure out a way to charge the battery, which may mean plumbing your engine to charge it (though if it's just the bilge pump, then charging at home should work as well, but you have to keep it topped up or you'll be buying a lot of batteries.)

How about looking at one of the lever type manual pumps, rather than a piston type (assuming you're using the piston type)? Something like:

Another option is to find an electric pump with a decent suction head, and you'd just have to run the pickup hose through the floor, and mount everything else above deck. Don't know if that's a realistic spec or not, though.

Luck;

Thanks for the replies. I have decided to skip the electric bilge idea. Keep the boat simple, no batteries. I have told my younger, stronger scuba buddy that it is now his sole responsibility to keep water out of the boat.

Sounds about right. Anyone else who happens to be diving off my boat is named "Windlass."

If its only a small amount of water that your trying to remove have you thought about using one of those cheap syphon type pumps used for fish tanks the ones that have a bulb you squeeze with your hand ,or using an old outboard fuel pipe and bulb.

i have also seen a small water foot pump used in one boat,the type used in camper/caravans that are used for pumping drinking water up to sink.

bilge pump

There is no problem at all to install a bilge pump in a SIB, in fact its a great idea (especially if pumping the bilge by hand gives you a hard time)

Have a look at the pictures, this installation was in a Milpro application in a RIB but it gives a good idea how it works. Most of the recent bilge pump has a built-in float switch so you just have to install the pump.

Like you can see on the picture, the blue plastic strainer (lower part of the pump) is removable, so by fixing it to the floor/bilge/transom/whereucan you'll just have to "click" the pump in place.

Electricty is quite easy too. If you have no electricity on board, you can use a small motorcycle 12 volts batterie inside a waterproof box (any electrical store have this) and put a breaker on the hot wire. For the switch, you have the choice between ON/OFF or ON/OFF/AUTO. On the 3 pos switch, you can put it auto so it primes when the float tells it to or manually overrun by putting it at ON. A good bilge pump should be self-priming and run-dry protected. In a previous project, we've installed the switch directly to the battery box, flush mount.

For the plumbing, you need hoses+scissors+tie-wrap. The bottom of the pump is the intake and you just have to run the hose overboard and thats it.

It is that easy!

Ok according to your lawyer profession you know that even an email advice has to be paid since it is a professionnal act, so how do you intend to pay me for my precious advices?
