The voltage dropping resistors are not water resistant though.

I am not sure how the bilge pumps are rated but I used to be heavily into saltwater aquariums. Using a valve to reduce the flow adds back pressure to the pumps and can significantly shorten their life. Aquarium pumps usually have a maximum head height to limit the back pressure (usually in inches of water). 6V is a better option IMO.
