What should the fuel to oil ratio be on a 1964 Evinrude?
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. Below is some additional information from our friend and frequent forum contributor Joe Reeves:
How many horsepower does an Evinrude outboard motor have?
Evinrude was founded by Ole Evinrude in Milwaukee, Wisconsin, in 1907. Evinrude filed for bankruptcy in 2000 and was bought by a Canadian company by the name of Bombardier Recreational Products. Evinrude produces two-stroke direct fuel-injected motors that vary between 25 and 300 horsepower.
Can a 7.5HP engine use a 50 / 1 mixture?
In years past OMC issued a bulletin that all their engines could use the 50/1 mixture, excepting the 1957 7.5hp model, and many boaters were using that 50/1 mixture in all the older models regardless of horsepower. I lost track of that bulletin unfortunately and if anyone has it, I’d appreciate having a copy of it.
When did Evinrude motors go out of business?

What is the oil mixture for an Evinrude outboard motor?
Evinrude outboard motors made since 1964 require a 50 to 1 fuel to oil mixture using 6 gallons of gas per 1 pint of oil. Motors made prior to 1964 take a 24 to 1 mixture. The most common mixture for motors made prior to 1955 was 16 to 1. Evinrude was founded by Ole Evinrude in Milwaukee, Wisconsin, in 1907.
What should mixture ratio be on Johnson Evinrude?
New engine break-in (not direct injection) requires 25:1 Please note that some Johnson and Evinrude Owners Manuals mention 100:1 mixture ratio after the motor is completely broken in, but most experts suggest against doing that. Stick with 50:1 for the 1964 and newer motors.
