Ive just bought a bas sboat with an 87 force and was wondering what mixture of gas an oil i should run, the guy at the marine shop says 100:1, my buddy said hell no run it at 50:1 and ive read online alot of people say run it at 24 or 36:1 for an older motor. This motor has only been run a total of about 2 minutes which have been this week. before this last week it hasnt been run in 3 years, because of this should i run it with more oil just to be safe?
