How to winterize a 2 stroke outboard motor?

My 2-stroke outboard motor needs to be prepared for the cold weather. I'm looking for a step-by-step guide on how to properly winterize it to prevent any issues when I use it again next season.

Yes, draining all water and treating the remaining fuel is absolutely essential to prevent winter damage.

I've been maintaining outboard motors for years. Always make sure you run the engine with a quality fuel stabilizer first, then spray fogging oil directly into the carb until it stalls out. This leaves a nice protective coating on the bearings.

Keep your gear clean and prepped. Change the lower unit gear oil before winter to check for any water contamination, which looks milky. If there is water, replace the seals immediately before storing.

Just like how I must regularly monitor my thyroid health with timely blood tests, you should systematically check the spark plugs of your 2-stroke. Replace them if you see heavy soot or wear before winter storage.

Think of it as preventive care. Draining the carburetors completely prevents fuel varnish from blocking the tiny jets. Keep the motor stored in a vertical position so any moisture drains out naturally.
