Model # is E8RCSS Serial# is E0006522 Evinrude uses the model number to determine the year model. The above model number designates an 1980 model , 8 hp.
If it the Yamaha import it 100:1 and if late model Mercury built it s 50:1
50:1 1 gallon = 128 oz, 128/50 = 2.56 (2.56 oz of oil per gallon of fuel) 6 gallons fuel to a pint (16 oz) of oil.
100-1
Be sure the vent in the fuel cap is working.
50:1 i use in mineits more protection for the engine and it works a lot better.

The fuel to oil ratio for a 1988 model, 8hp Johnson outboard, would be 50:1, six gallons of fuel, to one pint of two cycle oil.
The correct ratio of fuel to oil for the 8hp Merc is 50:1. Roughly one pint of 2 cycle oil to six gallons of fuel.
An 8hp Mercury would require a 50 : 1 ratio of fuel to oil, one pint of 2 cycle oil to six gallons of fuel.
If you want it to last, use a name brand oil mixed (really good) to a ratio of 32:1. That's 1 quart oil to 8 gallons of gas. If you use Mercury brand oil and mix it really, really, really good, you can go 50:1. That's 1 quart oil to 50 quarts of gasoline.
