Re: Mercury KG7 parts

Getting a old Mercury to run isn’t always easy. You can have 120 psi compression, great spark and a good carburetor and a mercury still may not start. A mercury has ball and roller bearing on the crankshaft and it needs a good oil seal on each end of the crank to hold crank case pressure. Over time these seals get hard and won’t seal. The seals are available but a little difficult to change.
