I have a mystery water leak that puts about 1/2 gal of water in my bilge for about 30 mins of engine operation. The history is as follows:
1. Noticed water in the bilge only after engine has been run, noticed increased drip from stuffing box, about 1 drip per 5 sec. OK that is the leak, tightened stuffing box nut to get leak down to recommended one drop per minute. No luck, leak still there
2. While fiddling around with packing nuts noticed stuffing box hose clamps not very tight. Installed 4 new clamps, well tightened, no luck, leak still there.
3. Noticed bad lead from weep hole in water pump, aha, ordered brand new water pump, Moyer model 502 from the ever helpful Ken, now I am in the 21st century regarding water pumps, no leaks, tight as a drum but $265 to the cause, cheap compared to an hour of a real mechanic. But no luck, leak still there.
4. Noticed hose clamps on Moyer SS water lift muffler exhaust not well seated. Had boat yard redo connections with fiberglass 45 deg elbow to get better angle, 4 new super clamps, no leak, aha, I got it. No luck, leak still there.
5. Coincidentally, at this point I noticed that my temperature gauge was not reading. Checked wire for continuity, OK. so the ever helpful Ken, suggested new Isso sender and guage, $85 more to the cause.
5. It must be the anti siphon valve in the water line going to the muffler input. Blew and sucked on that hose, seemed ok but just to make sure put that hose into a bucket, ran the engine, no leak there. But maybe my blowing and sucking on that valve unstuck it so went out for sail. Motored out of mooring about 20 mins, no leak in bilge, aha, success, I got that puppy. No luck, on the way back to the slip, motored about 20 mins and got 1/2 gal water in the bilge.
6. Looked with flashlight while engine was running back to the slip, could not see any leaks in any of the thru hulls nor could I find any water trails although from the position of the water in the bilge, it looks like the leak is coming from the front of the bilge area. Note T30 has engine mounted just aft the mast so that is where all the "stuff" is with the exception of the stuffing box.
I am baffled, any suggestions out there??
