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.
Matt, If engine is two stroke and not oil injected then yes you must mix 2 stroke oil and fuel. 4 stroke engine have a crank case which is filled to proper level with 4 stroke engine oil. Check the attached links,instruction and guides, Good luck

I'am amazed it doesn't have an oil premix that gives it auto oil mix.If it doesn't than the mixture is 50/1.That is fuel /oil ratio.e.g. 50 litres of fuel to 1 litre of oil.Hope this helps
It really depends on the engine. 50 to 1 is good in some and as oily as 32 to 1 in others. It is quite possible to have to carry 2 cans, 1 mixture for the main outboard and another mixture for a trolling motor. The dealers can tell you.
