You have given the serial number, which is no help. We need the model number - look on the plate again. All Johnson 3 horse outboards had a model number beginning with either JW or JH.
23 years old made in 1988
What is the horsepower
1964
50:1
A Johnson outboard, model number JW-17, would be a 3 hp engine, manufactured in 1961-62.
The required plug gap for a 25 hp Johnson outboard is .030 in.
At the end of the rope stupid
They are all 50 to 1
In order to determine the weight of a 1996 Johnson, the model number, or at least the engine horsepower must be known.
The 55 hp Johnson outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
The 1985 model, 50 hp Johnson outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
the 85 is the horsepower and the 75 is the year(1975)That is what I was told...I have same motor
