Hi All,
I have a 2007 Merc 115 EFI that I have recently pulled the powerhead and replaced the swivel pin, oil pump, impeller, and all the seals and gaskets (powerhead to adapter plate gasket, oil pump seals, impeller seals) as well as many other parts. I put everything back together following the service manual and torqued everything down to spec. I mounted the motor back on the boat put in the motor oil. I was not able to crank it as I was waiting for control cables and harness and left the motor trimmed down. Fast forward a few weeks and I noticed that there is an oil spot under the foot and oil leaking out of the raw water intake in the foot.
Needless to say, I felt gut-punched. Before I pull the motor and put it back on the stand to pull it all apart again, it would be great to some insight into what it might be or what to look for to narrow down my search. I looked all around the midsection cowling, the powerhead, and the oil pump that I can see by the swivel pin and as far as I can see it is all dry and no other leaking. I am not sure if its motor oil or gear oil. Is there a way to tell?
