I have a 3 1/2 hp Mercury 4 stroke
that I purchased a little over 3 years ago. It has less than an hour of running time. It starts and runs well but the lube oil
is draining. There is no sign of a leak on the exterior of the engine
but I have had to add oil
to the case to ring the level up in the sight glass. This occurs while the engine
is stored upright.
Anyone have any experience with this?
