Just got done with a 5 day cruise
. I had recently installed a Jabsco
36600 diaphragm bilge pump
. Less than 90 days old. Tested it, used it etc. Two days out of Bellingham I was in fairly rough seas in the straight of Juan De Fuca. Heard water
sloshing in the bilge
. Went down and checked the bilge pump
and it was blowing air into the bilge
not pumping water
out. So I disassembled the pump cleaned the check valves and reassembled it. Not much in the check valves. Nothing I thought could have been a problem. After I re installed the pump, it did the same thing. So I reversed the hoses. Started to draw water and then went into hydrostatic lock. Well duh the check valves would not allow water to flow in that direction. Then it dawned on me. The electric motor
was turning the wrong direction. So I put the hoses back on correctly checked that positive was still positive. It was. Sure enough still blowing air into the bilge. So I reversed the electrical
still turned the same direction.
Broke out the whale gusher and bailed the boat that way. I am however stumped at the problem. Any suggestions?
