You may use any quality TCW3 rated, 2 cycle oil.
50 to 1 oil and gas mixture
What would the gas oil mixture be for 1974mercury 7.5 HP outboardmotor?
My 2003 3.3hp outboard motor is 50:1 mixture.
I have the original gas tank for the same engine and it says 5 ounces per 5 gallons..
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.
normal is 50:1 16 ounces oil per 6 gallons of gas
Mixture of argon gas and Mercury gas.
50:1. 16 ounces oil to 6 gallons gas
you need a minimum of 87 octane gas
yes, a mixture of coolant and gas can and will ruin your motor
An 1985 model, 25 hp Mercury outboard requires a 50:1 fuel, to 2 cycle oil ratio.
I have the same motor. The proper mixture is 50:1, 6 gallons of gas to 16 oz of oil.
