Fluid Leak around Prop
have a 1990 50HP Johnson outboard that I have a question about.
cranking it the other day (as I do every month) and running it at idle
speed a few minutes (on the trailer with a flush attachment), I noticed a
gray color somewhat oily residue coming from the exhaust unit within prop.
I shut the engine off and cleaned it up a little. I checked the lower gear
case lube and it did not appear to have any foreign debris or water
present. Since I was checking the fluid, I went ahead and replaced it with
a few days later, I notice that I am still having a small amount of very
thick oily black/dark gray substance leaking very slowly around the back
of the prop even though I have not operated the engine since I have
changed the lower gear fluid.
idea what could cause this and is it an expensive repair job?
for the help.
is the unburned gas and oil that collects in the carbon deposits in the
center section. This stuff dissolves and drips out. We see it all the time
and it is just a mess, if nothing else. Not to worry.
