I had an omc v6 with a cobra outdrive.
I had a leak develop; and the estimate was 2x what hte boat was worth.
basically they have to pull the engine and outdrive out and then replace the
seal & put it all back & re-align -- nothing is "rocket science" but it's a lot
of labor....

I tried to figure out if I could use some sealant; but realized there's no way
to get it around all over -- just can't do it... at least on mine.

Good luck.. I know the guy who bought the boat bought a bigger bilge pump &
seems to be happy with it -- personally; leaks only get worse, they never get
better....

I have an older OMC I/O with a leak in the transom bellows? Is there a
temporary fix I can use to get me through the season.

What's a Guesstimate as to the co$t of replacing?
