Re: 1988 evinrude 4hp mix ratio??
i have an 85 rude 4.5 hp, it says 100:1, but i have always, from new mixed it 50:1. found out in this forum that there was a bulletin issued by omc, shortly after those 100:1 motors hit the market, to disreguard the 100:1, and go with 50:1. (my 1985 still runs as new)
