Re: Flotation
I have made a steam ejector out of one inch soldered copper tube fittimgs, with suction (standard one inch tee branch) about 1/2 inch above the bilge, and discharge 20 inches higher elevation into the paddlebox of the Margaret S. With a 0.1 inch steam nozzle @ 150 PSIG, 0.5 inch throat diameter, 10 USGPM flowrate. General form similar to the McMaster catalogue, but cost is far less than the several hundred dollars McMaster charges.

Re: Flotation
I view a bilge pump as a stop gap measure to gain time to fix the leak. Thus vigorous action is valued over other parameters.
Glancing at the electric bilge pump on my 25 foot I.C. boat, I see that it is rated at 42 gpm at moderate head. It is perhaps the size of a coconut and uses a 1.5" output hose.
I submerged it in a 5 gallon bucket when I bought it and then turned it on. Everyone nearby, including the cat, got wet.

If you think you are too small to make a difference, try sleeping with a mosquito.
