I have no idea what caused the seal to start leaking, but it is clearly shot. Oil
just runs right out after filling. Sounds like too big a job for me (at 74 years) to remove the tranny with the very tight quarters on my boat.
Still don't quite understand the "slide the shaft back in" concept
? That would be an easy fix it that's the problem.
Thanks for the tip on the yanmar
dealer in Ft Lauderdale.
