DeereRun97 Posted July 30, 2006 Posted July 30, 2006 Does anyone know what the oil & gas ratio is for a 1967 6hp evinrude is? Thanks Quote
RobDar Posted July 30, 2006 Posted July 30, 2006 someone on www.iboats.com forums will know...probably even have a manual for you. Quote
northgabassfisher Posted July 30, 2006 Posted July 30, 2006 I think its 50:1. I had a old 25 horse 67' evinrude on a jon boat and it was a 50:1 ratio, and rember to much oil is better then not enough Quote

Super User Way2slow Posted July 31, 2006 Super User Posted July 31, 2006 Even the older motors that used to recommend heavy mixes of oil can run a 50:1 ratio in TC-W3 oil. Reason being, in the early days of two strokes they didn't have oils they have now. Back in those 25:1 ratios those heavy mixes were needed because it was common to use 30W non detergent motor oil, the new oils have much greater lubricating properties than what was available back then.

DeereRun97 Posted July 31, 2006 Author Posted July 31, 2006 Did a search at Iboats and it is 50-1. Thanks all. Quote
SFC Hall Posted August 1, 2006 Posted August 1, 2006 so that is like 3.5 ounces per gallon... am I figuring right? Quote
Pa Angler Posted August 6, 2006 Posted August 6, 2006 Well let's do some math: There's a 128ozs in a gallon. 3.5 x 50 gives you enough for a 175ozs so if you divide 50 into 128 you would need 2.56ozs for a gallon for a 50 to 1 mix or for every 50ozs of fuel you would need 1oz of oil. You could get away with 3ozs per gallon. Hope this helps. 8-) Chow The Pa Angler Quote
