I have a relatively large and efficient bilge pump in my boat. But it can't suck up the last 2-3 inches of water at the very bottom. I'm looking for a solution to get rid of that last bit of water as it produces a lot of humidity and smell. Furthermore, the surveyor suggested I install a backup pump in case the primary fails.
I found that from Seachoice and from the picture I get the feeling this could work. Am I correct?
