What is the mix 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.

Gene - this boat typically has an outboard engine that is 9.9hp to 40hp. The gas tank that goes with either engine can be virtually any size you would like. I'd recommend a 12 gal for the bigger motor, principally because that is about as large as I can handle getting in and out of the boat. The smaller motor can feed from the 12 gal or I recommend a 4-6 gal separate tank since these motors quite often require oil to be added. Hope that helps. Fred

50/1. 1 pint to 5 gal

50:1 since the late 60's
Too much oil will gum up the rings, smoke too much and foul plugs. Use ONLY major outboard manufacturers oil, Mercury, Yamaha, Johnson/Evinrude TCW-3. They work the best, and no alcohol fuel.

50 to 1 ratio 16 ounces of oil for 6 gal of gas

your safe to mix 50:1 , it is 50 parts gas to 1 part oil, or 1 pint for every 6 gals gas, 89 octane, TCW3 O/B oil, also add some stabil

Hi, mix the gas and oil at 50 to 1 and use two cycle outboard oil. Regards Phil.

go to an auto parts store and get a can of gasoline additive called seafoam. Read the label so you know how much to add to your 6 gallon tank. This stuff works wonders on outboard motors.
