oil leaking from prop area

[ron w.]

hello ,

i have an evinrude 9.9, 1984 outboard, i noticed oil on the
floor of garage below the motor, over winter and looked like it was
coming out around prop, i took prop off and there was oil laying
in the prop housing. this oil is "black" in color, is this from my
exhaust? i also looked at the lower unit oil and there was no water
in there and the oil looked normal color. thanks ron w.

Its probably nothing to worry about. Did you fog your motor when you winterized it? Probably residue from that.

[ron w.]

well here is a dumb question. what do you mean by fog my engine?

[perchjerker]

No question is dumb, bud.

In the fall, you should get yourself a can of fogging oil. You spray it in the carb just before you put the engine to bed for the winter while its running, the idea is to lubricate the internal components of the engine.

Thats a brief description

Had the same scenario last spring with a 90 hp Johnson. It was just a little exhaust oil that dripped to the bottom over the winter. Ran the motor all summer without incident. I don't think you have a problem.

[ron w.]

hi perchjerker,
thanks for explaining. and no i did not do that.
but i will next winter. i thought maybe i was mixing the
gas to rich or something, i mix 50:1. motor runs fine at
this mixture and that is what i was told to use by the person i bought it from. anyways thanks again for your help.

No problem, buddy. I would suggest you pick up a service manual for you motor. It will be one of the best investments in your motor you can make.

Just remember, the one dumb question is the one you dont ask!

[Backwater Eddy]

Good question really!

I had the same concern a while back and came to realize it was residual oil from the heavily treated fuel mixture I run before I winterize the rig. Had me spooked too!

I did the same routine and checked to see if my seal had been pushed out by ice.

As we are on the subject what are some of the proffered brands of lower unit oils some of us WC.com folks like to use?

I have been told that it can be a good idea to run a case full of lighter oil (140/80 or the like) first to flush the case and then run the heavy oil.

Is this a good plan on the first outing in the cold water of spring, or foolish?

Thank you,

Eddy-
Never heard of that one. Might be ok, but I would rather just use the stuff the factory recommends and drain it after the first run or two if you want to flush it out. I would feel better having the proper viscosity oil in the unit at all times.

[Backwater Eddy]

True.

I was told it would flush the case better on older units. I do not think I would try it on a new unit with more specialized materials in the lower unit.

I think I will stick with the OMC snot I use now.

Thanks,

It seems obvious to me that you should check your lower unit seal. Happened to me 2-3 times.
Caused normally by getting line wrapped around the shaft and left alone it will force a rupture of the lower unit seal allowing water to mix with the lower unit oil and pretty soon no lubricant. At least get busy and check the lower unit oil and see if you have water in it. If not, then it just might be as these other say.
