OK team, you all walked me through pulling my 350 motor out of my 270 rinker, rebuilding my transom asy and back in the boat which was 100% sucessful for some time but back to leaking...
I did find that my shift boot cable had a tare in it, although I had replaced it so not sure what was up with that and thought my simple solution ( was able to replace it without pulling the out drive ) but still a leak. I tried to get a scope back in there but it's just to tight to get any useful views. I can see from the top of the motor I'm not leaking around the transom, steering pin, gimbal bearing...I'm feeling all my hoses and can't feel anything there either....I re sealed my trim manifold....I put all kinds of sealant on the transom ring when I put it back on and it is all squished out around the edges ( a mess I need to clean up ) and can't imagine anything is getting around that.
I tried the filling the bilge with water...zip.....
It leaks while sitting in the water with the motor not running so I assume it has to be something from at the raw water pump back. I have 4 thru hulls, nothing leaking there. It's a pretty good leak. My 350 is closed cooled, I have water from both the foot and a thru hull going to the raw water pump. So I have to get a better look at those hoses but one area I can't get to that absolutely keeps me up at night is the Y pipe not sealed properely on the transom asy. How can I check that? My exhaust bellows is off....I was thinking I could shove a hose in their and stuff some rags around it to get a somewhat seal on it and crank up the pressure, but since it also is the exhaust, assume water is going to go into bad places? I guess I can take the elbows off from the motor and somehow block them off so that water does not get to the motor.....I was concerned when I put the Y pipe on the bolt tourque was only 24 lbs and I don't recall it being any special fastners, I did put new ones on and anything that merc said to be there is there....
