What are these holes that leak lower unit gear oil,and what do I plug them with? Sorry if this is a stupid question but I'm new to working on outboards. '68 Chrysler 55hp
Those are weep holes meant to be there. The leakage is probably unburned fuel/oil mix. Thats normal. Smell the stuff. You'll know its gear oil right away if it is.
Thanks. It's gear oil...however, I took the lower unit apart and it is trashed!! So going to look for a lower unit. Any good ideas as to where to find one a good price?
