How to winterize a four stroke outboard motor?

Keep it professional. Change the engine oil, swap the oil filter, and run a high-quality fuel stabilizer through the system. Drain all raw water from the block to prevent freezing damage. It is a simple three-step process.

Bhai, engine oil badalna bahut zaroori hai winter se pehle, haan? Aur fuel tank mein stabilizer zaroor mila lena taaki petrol kharab na ho. Chhoti cheezein hain par engine safe rahega, na.

Does anyone else get super anxious that they might have missed a tiny water pocket inside the cooling passages? I always feel like I should flush it multiple times just to be absolutely sure nothing freezes.

Wiping down the outer casing with a little bit of protective spray or WD-40 keeps the rust away during damp winter months. It is a simple habit that keeps the outer metal body looking brand new.

My son and I do this together every winter to teach him how to maintain things properly. We make sure to disconnect the battery and put it on a trickle charger inside the house so it doesn't lose its charge in the cold.

I just did this for my dad's 4-stroke outboard. We flushed the motor with fresh water, changed the engine oil, and sprayed fogging oil into the spark plug cylinders. It took us less than an hour and it is totally ready for winter.
