1961
18hp
The 1972 model requires a 50:1 ratio, the 1960 model requires a ratio of 24:1.
I dont know how old this thread is, but my 18 hp johnson evinrude with serial number 18304 A is a 1973 model.
The oil mixture for that motor is 1 pint of oil to 6 gallons of gas
A 18hp Mercury outboard, serial number 5955388 is a 1982 year model.
An 18 hp Evinrude outboard, model 18202 would be a 1972 year model.
A 1957 Evinrude 18 hp weighs 85 pounds, so I would assume the Johnson 18 hp would be about the same, give or take a few pounds.
