1961 evinrude 18 hp fuel mix
can i use 40:1 mix in this motor or do i have to use 24:1 mix.
I've heard people on other forums that u can't use a 40:1 mix in 1961 evinrude 18 it has to be 24:1 according to omc because it has bronze parts on the crank all I'm asking is for someone to tell me if it has bronze Parts in the engine or not so I can figure out what to mix it for thanx.
