I have a 1984 90hp Mercury outboard and the fuel mixture is 50:1 which is one pint of 2 cycle motor oil for every 6 gallons of gas.
50to1
it's 50:1
mix 50:1
A 175hp Mercury outboard requires a 50:1 fuel to oil ratio.
50 to 1
all mercury outboards mix 50:1
The fuel to oil ratio for a 9hp Mercury outboard is 50:1, roughly one pint of 2 cycle oil, to six gallons of fuel.
The 2 stroke, 25 hp Mercury outboard requires a 50:1 ratio, this is roughly one pint of 2 cycle oil, to six gallons of fuel.
The 20 hp Mercury outboard requires a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
The 4.5 HP Mercury Outboard requires 50 to 1 fuel, to 2 cycle oil ratio. A mix of six gallons of gallons of fuel to one pint of oil is a good mix for the Outboard.
I believe it is 50 : 1 (16 oz. oil to 6 gallons gas)
A 4hp Mercury outboard requires a 50:1 fuel to 2 cycle oil mix.
