I dont know how old this thread is, but my 18 hp johnson evinrude with serial number 18304 A is a 1973 model.
An 18 hp Evinrude outboard, model 18202 would be a 1972 year model.
A 18hp Mercury outboard, serial number 5955388 is a 1982 year model.
1961
18hp
paid 150.00 for a 1972 in perfect shape
The fuel mix is 24:1
The 18hp Johnson Seahorse model FD-16A outboard motor was manufactured in 1965. This model is part of the Johnson Seahorse series, which was popular during that era for its reliability and performance. If you need more specific information about its features or history, feel free to ask!
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.
The 1972 model requires a 50:1 ratio, the 1960 model requires a ratio of 24:1.

The oil mixture for that motor is 1 pint of oil to 6 gallons of gas
You can't tell by the model number. You can tell by the serial numberI have the same one, it's a 1988. (18HP 6 speed (3 hi/3 lo) 44" deck, right?).
