Mercury 115 Oil injector broken. What ratio do I mix gas and oil in fuel tank?

[Kerry Elliott]

The oil injector is broken and the guy I bought the boat from says he has been mixing oil in the gas tank. I asked him how much or what ratio was he using. He said he just pours some in the tank. Can anyone tell me what ratio to mix the gas and oil for this 1989 mercury 115?

First of all, I'd be very leary on the condition of the motor given this response. To answer your question, most mercs run on 50:1 ratio. Any 2-cycle oil has the mixing ratio listed on the back of their container.

Oh, the birth of another mutha thread. Mr. Lucky! A man with a sense of humor, "this looks like the beginning of beautiful friendship" (Casabalanca, 1943) You have hit on the most controversial topic on this site. You asked the same question twice and got laconic reply. Make sure that the oil you use conforms to the Manufactures requirements. Wish me a Happy Birthday. Nobody will believe I am 92 :wink:
