I have a 1965 33hp evinrude outboard and was wondering what to mix the fuel at? i have herd 30:1 40:1 and 50:1. I have looked at the part manual i have and it does not say. My second question is about the gear oil. I replaced it last year when we rebuilt the foot. We did not get it running last year so i had it in the back of my truck to transport. it leaked out the foot oil in my truck. I talked to someone and he said that i could not lay it on a certain side. Is that true or is there a possible leak there too?
