93 Johnson 20hp Ratio?

PartsMan · Mar 7, 2011

Does anybody know what the gear ratio is on a 1993 Johnson 20hp?

I was playing with a prop calculator and need to know what to plug in.

I believe its 2:1.To make sure put your motor in gear take cover off & count how many times the flywheel goes around compared to the prop.

That's what I was thinking. Just thought someone might know for sure here.

I took her out yesterday and I am WAY over propped.
