Need fuel mixture ratio for Johnson 20hp tracker

[Fearless Fred]

I think this Johnson 20hp motor is about an '86. Not sure. The model is TJ20CRCEM and Serial #R08255025. Can anyone reccomend the correct mixture and type of oil to use?

50:1, 2% or 1pint in 6 gallons is near enough using a 2 stroke outboard engine oil of TCW3 spec

A 1989 model in fact (CE).
