hmm. had posted last night but must not have posted it. I did get into the bilge to clean up a bit. A little more history on this, have been tracing a minor leak for about the last two years. Nothing that would even kick the pump on, just bothered me to have any water in the hull. I had a coupler repair about that time and seems like I have had this problem since. Until recently I concluded it was the a/c which drains into the bilge because I just could not find a leak. I tested the thru hulls by putting powder around them and using a fake lake on each of them and got zip. I had a problem with my black water tank, fixed that (yuk) and thought that was the problem. Then, the last time I had the boat out for a couple of days ( April!), the pump would come on with an over night stay so I knew something was up. I saw a slight leak in the transom, although I think now that was from where the speedo come thru, and assumed it was the bellows and did that repair. They were fine but I'm sure time wise was time anyway and then when I dunked it, was really leaking.
So, yesterday I put the plug in just to see and I for sure have a leak around the gimbal ring- but also the thru hull for the engine cooling was leaking pretty well also which was really a shock. The hose is still on from the inside and the valve turned off so it is leaking around the seal. With the testing I had done before, that was a shock. Anyway, I had filled it up with a lot of water and was leaking at the bottom of the ring, obviously hard to tell if that is the only spot leaking as I could not fill up the bilge but the transom assy will have to come apart and see what I have going on. I have other stuff to do so will probably be weekend after next before I can get back on it. What a mess!
