model # 10824m
serial # 7007326

i just purchased this motor for a good price, but it has been stored for a year or two, apparently it use to work perfect but has not been touched, what should i check first ,i was wondering if anyone knows what plugs,gap, oil mixture, foot oil(lower unit) tips for tuneup or common problems these are prone too, what to watch out for, also maybe a paint color # if you know the one, thanks a lot for your help

Re: 1978 Evinrude 9.9 Questions

fuel mixture is 50:1 TC-W3 outboard oil, Champion Spark Plugs, QL77JC4 gapped at .030. there are all the tips in the TOP SECRET FILE, top of this forum.

great motor. will definately need a water pump kit, probably carb cleaning and rebuild kit.
