Proper oil for air cooled Gamefisher

[garry-in-michigan]

I find that worriesome. By having the fill and vent at the top of the gear case leaves oil as the only alturnative. Grease could possible have voids around the gears. (Cornhead grease is best in this regard.) Since oil floats on top of water, it gives you no way to drain the gearcase or check for water except to remove the skeg. That would possibly damage the gasket and you might have to make one , if a new one is unavailable. . . 🙄

The safe bet for the engine is IMHO to run air cooled 2-stroke oil in it. If it were mine I would probably run full synthetic outboard oil in it, but that’s maybe a little experimental on my part so I will not recommended that to others without saying that is a try at your own risk prospect.

Garry your thinking is exactly what I was mulling over. There is no drain screw for the oil in the lower unit. That made me think
grease is to be used. I did not want to drop the lower unit cover for fear of not finding the proper rubber gasket if this unit does
use oil. The Sears Parts Direct site clearly shows oil seals and ball bearings in the gear case so I still think it uses oil but…

I will have to find a website that knows more about the motors. Thanks.

The book calls for SAE 90 outboard gear oil, so your Merc stuff should be OK. Fill the motor in upright position.

If you have anything in there to drain, remove the plugs and lay the motor on its side.

All set. Removed both plugs at the same time then tilted the gear case. Finally got the gear oil to flow out.
It was very clean but only a few ounces were in it. Used my Merc pump and gear lube now I’m set.
