can someone get me an online service manual for 78 and up smaller omc outboards. I downloaded one but it ended up for 78 and down outboards and i have an 87. I know that i can buy one but they are a rip off. if not, does anyone know the operating rpm for at least an 87 25hp for sure, I would like to know the operating rpms for the 25, 30, and 35 hp and how they change year to year.
thanks.
thanks.
