I keep my boat in the water and have a bilge pump, my problem is: when im underway if i turn on the bilge pump every few minutes, there always seems to be some water to be pumped out, I'm not taking water over the transom, nor is the water comming from above deck and the plug is in the stern hole, Where can this water becomming from? My bilge pump is in the sump( i think that is what you guys call it). Mind you it's not a lot of water each time the bilge pump goes on either manualy or auto, but it adds up. Clueless?

One explantion for why you would take on water when underway but not at a standstill is that maybe you once had a speedometer that that has since been disconnected. The speedometer may have worked by bringing water to the meter in the console--the faster you went the more water came through the tube. Now that you have disconnected the speedometer, water just runs out the tube, which you have forgotten about, since it ends in the tunnel. Maybe?

David, that is a poosible theory I guess. I just recently bought the boat (86 Montauk) how would I further investigate that theory?

Do you have something that looks a bit like a transducer on the bottom of your transom? It would have a tube (that might look like a wire) coming off of it and enterning the boat.

I do have a transducer, but I belive that is for the current fishfinder

This speedometer style that I am referring to would be shaped like a short pencil sticking down, unlike a transducer, which would have a flat bottom the side of a half dollar.

I mean the size of a half dollar :)

Just because the bilge pump comes on doesn't mean it is actually pumping water. In automatic mode the water sloshing around in the sump can cause the pump to start and stop frequently. Starting manually can cause the pump to spit a small amount of water many times. Try not turning the pump on/disconnect temporarily and see if water is actually accumulating.

I dont think so, either way there is only one wire and im pretty sure it's for the fishfinder, Besides I think it may be accumalting a small amount of water with the boat docked, not sure though. I'm thinking maybe the plug is not tight enough, but then again wouldn't water exit the boat when underway? I guess I'll have to pull the boat out of the water (a pain in the ass for me,no lift, no trailer) and see if there is a hole in the hull. If water was entering the hull would it wind up in the tunnel and sump? Still confused

Aubv, I underatnd from experince what you mean, but when im underway it's real water the bilge is pumping, not just spitting, it pumps for about 7 seconds then spits, then nothing..then If i try the bilge a minute later it's the same thing. It's hard to watch what the bilge is doing automaticaly because i cant hear it above the engine and dont like to look back to often or else I'll run into someone or something...

I've encountered the same problem in my "big" boat. I don't know if you are in salt or fresh water,but I discovered that the water I take on is fresh water not salt that I'm in. (I tasted it!) When I wash down my boat after every use,water is getting in the bilge thru rod holder ports and the rodholder storage holes in the cockpit.Just before I begin to plane and in the bow-up position, I turn on the bilge and de-water the boat.My stern is a little higher than the bottom of the keel and when I open the bilge hatch at dockside no water is visable. This could be happening to you.
