most all outboards are 50 to 1 ratio. you could run a little richer. not much. It is not like a weed eater that is 40 to 1. Always make sure if the motor has not been run for a season. Pull the plugs and shot some wd- 40 in the cylinders. Always run your engine fuel rich at the end of the season before storing. That is run it rich and unplug the fuel line and let the engine run out of that fuel.
A 1960 model, 18 hp Evinrude outboard requires a 24:1 ratio.
Motor should be fine as long as no water got into the cylinders
It is impossible to tell the Mercury Outboard year model without knowing the horsepower but 14 numbers are possibley 1960 onwards
I have a late 1960's Ted Williams air-cooled 7.5 hp outboard produced by Eska with the manual. The manual states 24:1. Hope it helps.

50:1 is usual, 32:1 is also OK according to some.
