Why bother with winterizing? 4 questions....

Do you want to rebuild or clean all the carburetors in the spring?
Running Stabilizer through the fuel lines, squeeze bulb, fuel pump, and carburetors keeps the compounds in the gas from separating; which causes deposits that will plug the carburetors.

Do you want rust to form inside your engine that will shorten it's life by many years?
Spraying or Injecting fogging oil into the engine coats all the 'steel parts' with a layer of WAX. This stops rust from forming inside the engine during the winter. The WAX is disovled away by the gasoline while the engine is running in the spring time.

Do you want a new lower unit in the spring time,
because yours had water in it that froze and cracked the housing?
Draining and refilling the lower unit with new lube will get any water out, if it is there. Fresh lube will help make the gears and bearings last longer, you will be ready to go for spring time.

Do you want to buy a new engine block for your inboard or inboard-outboard?
The water jackets in the block, cooling pumps, and exaust manifolds must be drained and charged with RV antifreeze. This will keep them from freezing and cracking.
