The last trip I noticed drive oil in the bilge. I thought it was the reservoir hose, I checked it and that wasn't it. I believe the oil is coming from the shaft seal thru the bellows. I changed the motor last spring, and I thought the alignment was pretty good. We've used the boat a lot and felt no vibrations. Almost forgot…. 95-18 Alfa 1 Gen 2 MPI from a TBI… Any suggestions/help is "greatly" appreciated.
