My bildge pump runs frequently while the boat is in motion, motoring or sailing. Since it dose not while anchored or while in the slip, my first thought was of the stuffing box dripping, but I sail in reverse(no turning shaft, no drip). My next thought was maybe this was water trapped in the "grid" and did not get to the weep hole until the boat was in motion? Now I am thinking maybe I have a leak in one of the scubber lines or the exhaust pipe, because they are not below the water-line except when the boat is in motion? What do you think? Thanks, Bob

Thats a good one!
First, how do you sail in reverse<haha>. Bob, check your raw water intake when you are under way. I could imagine that the pressure of being underway could be forcing water into the boat thru the raw water strainer. Maybe you have a cracked hose or something else that is allowing water in. I would also check how much water you are taking on while your engine IS running (in gear). If the water accumulating in the engine bilge or the main bilge? You did not mention if the water is fresh or salt. I just found out that my water tank is leaking in the aft berth. You may want to check the fill and vent hoses (if it is fresh water). You may have a combination any of these things in which case you would not be able to tell if it is the fresh water tank. The only other thing would be the muffler/ thru hull for the exhaust. When you are under sail/power, the stern tends to sink lower in the water. That should be a lot of fun, getting into the PIT while under way (do you have any kids). Cannot think of much else except the fact that there is the head sink drain. That thru hull is above the water line. If that hose or thru hull fitting where leaking you would take on water while you are on a port tack. This would also be the case with the exhaust too. One other thing. What about the cockpit drains? Let us know what you find out.

Cockpit scuppers?
I mention that because I know mine leak. They exit below the waterline when on a tack. In fact even in small waves at rest. But not a problem at the dock. Right where the scupper hose connects to the glassed thru-hull. Could be from winter freezing. Even though my boat(H37C) is covered I know water gets into the cockpit.

Toe Rails ?
I had a similar problem, although it sounds like to a lesser extent. I tightenned up the toerails and get very little water in the boat now. It only happenned underway because, as you said, it would get trapped and obly drain to the bilge when the boat was in motion. Good luck. Duane

Could be serious
Something is opening up or overflowing underway. To start with, it is probably only a partial problem. I think it is bound to get worse, the only issue is fast or slow. Of course, the most likely event is a total failure (of whatever it is) in the worst possible conditions - by definition, that is when high stress is most likely to take a component to yielding. We had this problem this summer. Moved all the cushions, rugs, and covers and got underway with an escort in heavy weather. Finally the admirable Admiral spotted a flow by the engine. In our case it turned out to be a cockpit drain hose that fell out of its fitting. But our imagination had created everything from a shifting keel joint to a split high up on the hull. I'd get pretty focused about diagnosing this one! David Lady Lillie '77 h27

Have the same problem
Bob, my 27 started the same thing two month ago. Last weekend while sailing at night I took a flashlight and crawled into the engine box, with engine off. Found a small trickle of water coming from behind the rear engine bulkhead, thought it was the exhaust hose or muffler. This Monday pulled engine and bulkhead and muffler and all were ok. Found the propeller strut thru bolts were leaking. Seems when boat was at rest they would slowly seal themselves and not leak, but under power or sail the strut would move just enough to start them leaking. I am having the boat hauled out this Monday and all through hull fittings replaced. Had planned to haul the boat in November and replace all fittings so that is not unexpected but did not expect to have to do anything to the strut, glad the bolts leaked now instead of after all the work had been done and I put the boat back into the water! Let us know what you find!

I have suspected the muffler, but can't seem to find it. I was told it was under the fuel tank, but the tank is strapped down with nylon straps that I don't won't to cut unless I absolutly have to. Bob

Maby muffler
I had the samme problem, It trrned out that the muffler which was fastened under the fuel tank had a hole in it, and it was impossible to get out without removing the fuel tank , so I left it in and ran a new exhaust hose and a new plastic nnmuffler behind the old one and solved the problem

Check that muffler
had a similar problem with my H 27 1978) there was a pin hole in the underside of the muffler that allowed a steady stream of water to enter the bilge whenever the motor wasin operation.
