Re: Pumps do not do what you think
One of the best stock setups I have seen was the big Edson manual pump mounted at the foot of the companionway on a Santa Cruz 52. Slot in the sole section gave it away...
The broker told us that owners often referred to it as their "Oh My God" pump!
Gallon a stroke!
Handle was about 4' long.
You'd still have to have someone finding the leak and doing damage control, as others have pointed out.
