You are the MAN! I just bought a 1969 9.8 Merc 110 and the lower unit is leaking oil. Never pulled an engine apart before so thank you very much for sharing this with us. Good fishing and take care!
Hey! I just bought a 1968 9.8 110 and the it was bone dry when I removed the plug on the lower. Separated the lower and shot wd40 all in there to remove rusty water. Flushed with oil several times but now I’m noticing a small leak from the skag and prop like it’s leaking at prop seal. any advice or diagram links to help narrow down the seals needed? Thanks! I’ll probably replace the one you just did in this video as well
