How do you winterize 2 stroke outboard motor?

Answer 1

1. Add fuel stablizer to the existing gas.
2. Run for at least 15 min to get the stabilized fuel well into the engine

Drain the carbs too. Even if you disconnect the fuel line and let the engine stall there is som gas left in the carbs. You might have some dirt and water there. Stabilizer or not, the gas, dirt and water left in the carbs can turn to jell over the winter

Take your prop off and grease the shaft. Make sure your prop nut is torqued to your engine specs.

I would also run a flush with some marine antifreeze. You can pick this up at west marine. Its a jug that you fill with the pink stuff and connect it your garden hose and then to the motor.

You flush you motor until it warms up and then turn the valve on the jug and it lets the antifreeze go in.

This way you can eliminate any water from freezing inside.
