How do you winterize a 25 hp Yamaha 4 stroke outboard motor?

Answer 1

To winterize a 25 hp Yamaha 4-stroke outboard motor, start by changing the engine oil and replacing the oil filter to remove contaminants. Next, flush the cooling system with fresh water and add appropriate antifreeze to prevent freezing. Stabilize the fuel by adding a fuel stabilizer and running the engine for a few minutes to ensure it's mixed well. Finally, remove the spark plugs, add a few drops of oil into each cylinder, and replace the plugs, then store the motor in a dry, protected area.
