Re: Blown outboard prop shaft seal?
Before you have it worked on suggest you drain the crankcase oil. If the oil leak is still there it is probably gear oil. If the leak stops, it is probably crankcase oil. Maybe first , just put it in its normal upright position and see if it continues to leak. Maybe either crankcase or gear case were overfilled prior to storing it on its side? Try the easy things before ripping it apart?
I have had many outboards over the years and never had a prop shaft seal fail. Winding up monofilament in the prop can "suck" it into the seal and damage it. Maybe running in very muddy or sandy water may wear it out quickly?
