[QUOTE="LionHeart, post: 435681, member: 22379"] Hey guys, got a question about something I noticed while running my 1986 Johnson 15 hp on muffs today. I finally got the lower unit back together after replacing the outer prop seal. I then refilled with new oil and ran the motor on idle for roughly 5 minutes. Before that, it has been a year or so since the motor has run. An hour later, I noticed this brown goop leaking from the prop. Is this unburned fuel/oil from the exhaust? Or did I botch the lower unit seal replacement? I drained about a tablespoon of oil out of the lower unit and it looked fine. [/QUOTE]
