50 : 1 is the correct fuel mixture
50;1
I have a 1999 Mercury 2stroke 5HP outboard and the owners manual states 50:1 Gas/Oil mixture.
50:1
the mixture is 50:1
50:1 I believe
50-1
50:1
50:1
Mercury outboards prior to 1966 use a 24:1 fuel to oil ratio.
A 4hp Mercury outboard requires a 50:1 fuel to 2 cycle oil mix.
A 115hp Mercury outboard boat motor has a fuel to oil ratio of 50 to 1. This translates to 16 ounces of 2-cycle oil to every 6 gallons of fuel.
