I have the same motor and use 50:1.
For the 1995 model 40 hp Evinrude, mix at a 50:1 ratio.
50:1 on slow use and 40:1 on every day use
45:1 in hot weather 50:1 in cold weather...
im trying to find out what to mix the gas at for a 40 hp evinrude outboard motor
50 to 1
More than likely 50:1. But not guaranteed. Depends on the year and model. Always err on the side of TOO MUCH oil. May smoke but may save engine.
40:1 is the fuel mixture per the manual
The correct mixture is 50:1...or 1 pint to 6 gallons...if possible use the OMC Johnson/Evinrude oil, Do not add more oil than that, you will loose power. Also I recommend adding SeaFoam to each tank. It decarbonizes the engine as well as preserves the fuel. 1/3 can to 6 gal with 1 pint of oil.
40:1
Mixture is 40:1.
The correct mixture is 50:1
40:1 is a good mixture.
