How do you winterize 250pro xs mercury outboard?

Answer 1

To winterize a Mercury 250 Pro XS outboard, begin by flushing the engine with fresh water to remove salt and debris. Change the engine oil and filter, and inspect the fuel system, adding fuel stabilizer to the tank. Run the engine briefly to circulate the stabilizer, then fog the cylinders with a fogging oil to protect against corrosion. Finally, store the motor in a dry, covered area to prevent moisture accumulation.
