It's a Canadian made, 1979 50hp 4 cylinder. The american serial # equivalent range is 5193259 - 5531629.

Mix the fuel/oil at 50:1 ratio. Use TCW-3 2-stroke engine oil.

Contact your local Mercury Marine dealer for a Service Manual or check out e-bay.

He means that the fuel to oil ratio is 50 to 1.
That's 50 parts gasoline to 1 part TCW-3, 2 stroke oil.
For example 50 oz of gasoline to 1 ounce of oil.
