Re: 1987 Johnson 9.9 upper crank seal

Thanks guys for all the input. I pulled the flywheel and it’s definitley leaking. I ordered a new one. There are no obstructions in any of the air inlets. Chris P asked rpm difference and I checked with my tiny tach and it was 375 rpm difference. I wouldn’t have been concerned had I not seen the oil mixture. I looked around for any signs of a exhaust leak and found none. I have no history on this motor it was part of a 50 motor gift from a mentor who past away. Thank again Dave
