Mariner Outboard 3.3 Fuel Mixtgure

[Roger Blake]

A little off the subject of a C34...I have the subject dingy motor (2.5hp) and left my service manual on the boat. Had to bring the motor home for repairs. Does anyone know the fuel mixture ratio? From searching the Internet, appears to be 50:1...but haven't found anything definitive.

Roger : You are correct with the 50:1 mixture.  Don't forget to also add some fuel stabilizer and a dash of "carburetor/injector cleaner" to your gas. Those additives dissolve any gum/tar and keeps them from forming.  A thought

Thanks Ron...I'll pick the other additives up today.
