Hi Guys:
I'm new to the forum. I'm trying to help my brother in-law out with his 1985 7.5HP Honda 4-stroke.
He bought this 2 summers ago used from the original owner that took excellent care of the motor and regularly had it professional serviced.
Under the cover, the thing looks brand new.
At any rate, when my brother in-law took out of storage from the winter this year and ran the motor, he noticed oil had leaked out and was dripping on the side...
He noticed the oil dripping where the red arrow is pointed in the pic:
He took this to a local Honda dealer (not same dealer as original owner) and asked them to replace the water impeller and check on the oil leak (Impeller replacement unrelated).
The dealer replaced the impeller, then told him that it would cost him $1000 plus as there was a seal gone bad internally and leaking oil.
He picked the motor up over the weekend and this is where I have got involved to try and help him out.
We put the motor on a stand, ran it for awhile and found it dripping some oil out from what looked to be the top of the motor under the fly wheel.
I pulled the flywheel to be able to look better and also found the attached illustration online.
I have (2) questions before I proceed further...
1) I'm wondering if the oil seal item 10 is a common part to fail on a motor of this age...I am thinking this is the area of the source of the oil leak... If this is the case, is it as simple as taking the top nut of and pull the seal out with a pic or something like that? I see the part is only $10 online various places.
2) Could this be something as simple as too much oil being added? Before we go further, I am thinking of draining some oil from the engine and running again. If we try step 2, would it be safe to spray some de-greaser and warm water to clean off the existing oil to make the leak easier to see where it is coming from?
Appreciate any advice guys...trying to get my brother in-law back into the walleyes....
Tony
