Re: bilge pump 1988 sea ray 268
the pump should be just in front of the engine, when you open the engine cover/deck, look straight down.
there should be switches on the port/left side of the "steering wheel"
"I think" the one marked bilge pump will only work if the batteries are switched to the on position, you turn it on and off manually, dont leave it on after the waters pumped out, the bilge pump may also have a foot switch that comes on when the water level comes up to engage it.
the may also be a seperate step pump located in the aft cabin, same thing with the switch, look to see if the waters being pumped out the turn it off, dont burn it out.
also the searays should be self bailing to a point (drains around the floor area directly to the outside of the hull) as long as they are not plugged or cracked.
