I've posted earlier on the problem...Here is whats happening. While sitting on my trailer with the motor down, I am leaking foot oil above the Vent/Drain Plugs on the foot of my motor. I can smell the oil, its honey colored and smells just like the Penzoil LU oil I put in it a month ago. It looks like its leaking where the shift rod goes down into the foot. Is it possible for it to leak above the fill/vent holes yet not in the water??? I wipe it off every afternoon after getting home. Does it overflow after sitting in the hot sun? When I take it in the water there is a small slick, along with the smell of this oil. I plan on draining the entire LU and putting in new fill/drain gaskets this weekend to see what kind of oil/water I have. Any thoughts? This seem strange to me. Thanks!:eek:

Re: 1999 Johnson 115 Lower Unit Leak

it is normal to get exhaust residue, but not gear oil, if full, it could expand in the sun, and leak out the driveshaft or shift rod seal. you are on the right track to check the lower oil.
