A 175hp Mercury outboard requires a 50:1 fuel to oil ratio.
i have a 25 hp mariner and i use a 50:1 mixture
The 1998 model Mariner outboards use a 50:1 ratio.
A 40 hp Mariner outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
Buy a fuel tank, primer ball, motor fitting, and some fuel line.
50to1
you need a minimum of 87 octane gas
What is the oil to gas ratio for a 15 hp force outboard moter
50 parts gas 1 part oil so 1 pint of oil for every 6 gallons of gas
I always run my 2 cycle outboards at a 50 to 1 ratio. also be sure you are using outboard 2 cycle. not all 2cycle oil is the same!
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.
50 to 1 6 gallons of gas 1 pint oil
