Re: '88 Johnson 25hp fuel/oil ratio
Just to add the comment that for a few years in the 1980s from '85 OMC flirted with 100:1 mixtures before realising their mistake and reverting to 50:1 for all after 1964, including those sold and marked for 100:1
50:1 it is therefore regardless of any advice, decals or owners manual to the contrary
