So I've been working on getting my old 1967 Tri hull with a mercury 80 horse outboard back on the water. The guy that had it before me said that it did have a bilge pump but I cant get it to kick on with the switch that I think might control it on the dash. Can anyone tell me where the pump might be located in the boat? I want to make sure its function prior to getting on the water. I appreciate your help.
