Re: Fuel Ratio??
hello again raider. yeah, it will hurt the motor if you have too little oil. Because the old outboards don't have separate oil tanks, all of the internak lubrication for the motor comes from the oil mixed in with the gas. Without enough of it your motor will run hot and potential seize up at which point it will be toast. Generally speaking, the older a 2 stroke motor is, the more oil you'll have to add to the fuel. OMC motors up to about the late 50's ran on 16:1 mixes and smoked quite abit and often left a bit of an oil slick in their wake. In the 60's and 70's changes in technology and engineering along with stricter environmental laws caused motors to be run at 24:1. More modern 2 stokes (mid 80's on, or so) usually run 32:1 or 50:1, which is probably how you got 40:1 as a ratio (basically in between the two), but that only applies to newer motors. However, as yours is a 1960 model you will need the 24:1 mix described above. Some folks even add a bit more oil just to be on the safe side. It never hurts to have a little extra lubrication in an old motor.
