Re: oil mixtuer for 57 evinrude 7.5 hp
Hi Tracker, you should try this on the outboards section. With due respect to Lark 40, I would stick with the 24:1 ratio on the 57. That year used bushing in the top end, they did not change to rollerbearings till later. The bushing needs the higher oil ratio. One half pint of oil to one gallon of gas is what should be printed on the label on your pressurized tank. My 2cents anyway.
