it's probabally for 3 gallons of gas 8 oz of 2 cycle oil. I've had a few 70's engines and that was hte ratio for all of them.

10R76R is a 1976 model, 9.9 hp Johnson outboard.
I have a 1976 Johnson 115 and the ratio I use is 50 to 1. Rob, Dallas, TX.
Mercury outboards manufactured in 1976 require a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
A 65 hp Mercury outboard, serial number 4574019, is a 1976 year model.
The 1976 model, 55 hp Evinrude outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
im trying to find out what to mix the gas at for a 40 hp evinrude outboard motor
The 1976 year model, (ser.#4420321), 4.5hp Mercury outboard, requires a 50:1 fuel, to 2 cycle oil ratio. Mixing one pint of oil, to six gallons of fuel, will be a good mix.
50:1
All Chrysler motors built after 1969 use a 50:1 mixture
the ratio should be aproximately 16 to 1. so for every 6 gallons of gas you should use 8 ounces of oil
On the 1976 model, 85 hp Evinrude, the overheat circuit is the only alarm system on the engine. Check the temperature on each head, due to independent thermostats, for an overheat condition.
