Yes, that's the serial number - 7134221.

What is the horsepower?

 

[theshoaibahmed]

Its say 50hp. I need service manual so i can do oil change, spark plug. Need to know when i am filling the gas, do i need to mix oil as well. (thats what heard) and if one brother help me out how to fix the leaking gas from the gaskit area (the cup got hole) in it. When it runs, it leak gas.

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.

Thanks mohawkmtrs. For really good information. The only thing i want to know when we talk about 50:1... What is this means.

 

[Alumarine]

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.

You can use a 75W90 or 80W90 or 90W marine gear oil.

Here is a link to a manual for a motor that's newer than yours but it might still be helpful.
