What is the fuel ratio for a Johnson outboard motor?

Any Johnson outboard motor built since 1964 requires a 50/1 fuel ratio. Motors built prior to that date require a 32/1 ratio, with the exception of a few fishing motors built prior to 1955 that use a 16/1 ratio. Johnson outboard motors are two-cycle engines.

What is the best fuel mix for outboard motor?

The ‘Fallback’ fuel mix If all else fails and you’re absolutely stuck we recommend a mix of 50:1 for outboards older than 1980 and 100:1 for outboards manufactured since 1980. That is 50 parts fuel to 1 part oil and 100 parts fuel to 1 part oil respectively. By no means perfect but a good general rule.

What is the correct oil to fuel ratio for a motor?

Stick with 50:1 for the 1964 and newer motors. Models that have working VRO Pumps (Variable Ratio Oilers) do not require oil to be mixed with fuel. The pump is doing the mixing.
