Since the gasoline we purchase these days leaves a lot to be desired, I have been recommending high octane fuel to my customers. Also, avoid fuel containing ethanol for use in your outboard.
What is proper oil to gas ratio for a 1998 50hp Evenrude outboard
50:1 ratio
A 1973, 50hp Evinrude outboard uses a 50:1 fuel to oil ratio.
The gas/oil mix for a Force 50hp outboard is 1:50

2%
A 175hp Mercury outboard requires a 50:1 fuel to oil ratio.
My 2003 3.3hp outboard motor is 50:1 mixture.
Buy a fuel tank, primer ball, motor fitting, and some fuel line.
