I've noticed when I 1st start up that a small amount of oil drips out near the thru-hub exhaust. I'm not using an excessive amount of oil now, but is this something to be concerned with for the future?
The motor is a 60HP Evinrude.

I have the sane problem w/ my 1986 johnson 60 (same engine I think) I droped the lower unit to intall a new water pump checked all seals they were ok drained and checkeg gear lube no water. I was told by a mechanic that the oil driping out of the exhaust was normal and comeing from the exhaust not gear case. Im not sure if he was right or not but im pretty sure my gear case is not leaking.
Anyone else have any ideas?

The lower unit lube has a very different
smell than 2-stroke oil.

But how do you see the oil drip out, given
that the boat should be in the water when
you start it?

Good question Chuck, I thought of that after I posted. It's my 'in the driveway ritual', that I do once, or every other a week, to be sure I'm ready to launch.
It's not the lower unit oil, and it is coming from the hub-exhaust; so that's good to hear that it's a semi-normal occurence; and we do have the same motor (mine's an '87), hanging off the bk end of the same boat!
Thnx & anymore info will be appreciated.

I used a product buy omc called"engine tune" I asked for a decarboniser and the johnson dealer gave me that. Its an aresol spray that you run the engine at high idle and spray the entire can into the engine shut it down let it sit for 3-16 hours (I let it sit 8 hours) and then simply run the engine for atleast 15 min. Omc recomends useing new plugs after you run it for 15 min.
while it was sitting for the 8 hours about 6-9 ounces of brown nasty looking brown sludge
driped out of the area where we were having the small drips of oil afer running. Wow what a diffrence it made the boat seems to have alot more power and im not getting the oil drip I used to get. It is running better than ever. I use my boat about every weekend for fishing. the usual routine is put in at the ramp idle in a no wake zone for about 45 min to get to the inlet run about 5 min at high speed to get out in the ocean and usualy start fishing(slow troling live bait) so my engine dosent run very much above idle. the dealer says this was causing the problem. Anyway I suggest you use the "engine tune"

I'm not having that prob anymore, Rick, perhaps it's due to me hardly ever running at idle :)
I tend to do alot of cruising, tubing, or anchoring to fish.
Thnx for the info though

My Merc people tell me that oily sludge dripping from the exhaust is usually from idling on a over-rich low speed carb adjustment. Sure enough, I leaned up the carbs and it disappeared.

Ihg any idea how to adjust richness of fuel on a 1986 johnson 60?

My 1985 Merc 115's have a low speed mixture adjustment screw on each carb, but I don't have the slightest idea of what to do on your engine. Sorry. I know that the newer carb engines don't have any mixture adjustments any longer, probably for the better.
