Re: Outboard leak
That hole is in the exhaust chamber side of the lower unit housing. If your leaking oil from there something must be preventing the oil to burn up as part of the exhaust gasses.
Check and see if your plugs are black oily, could be engine is running cold or improper 2 cycle oil mixture.
I also saw engines leak oil out of that hole where the drive shaft seal failed and was blowing oil out into the exhaust housing. Lower unit needs to be dropped to fix....at that point do yourself a favor and change the water pump out, that seal usually comes in the kit.
My ability to remember lyrics from songs of the 60's far exceed my ability to remember why I walked into the kitchen
