i've winterized my 100 hp Yamaha 4 stroke every year by taking it to my dealer and saying, "Winterize this please, call me when you're done and I will come and pick it up and pay you."  For me, this is generally an early December exercise.

Fog the engine and change lower unit oil. Done. This is one reason I'm glad I'm in Louisiana.... no winterizing. Fishing 365 if you want

I learned from a guy who was a boat and automobile mechanic.

 

 

1.) Lower Unit Oil:

 

Do not change the lower unit oil in the winter. Just open up the lower plug to see if any water comes out, if it does, let it all drain out and then put the plug back. Change out the lower unit oil in the spring.

 

 

 

 

2.) Fog the engine:

 

Take out the spark plugs. Shoot 2-3 good squirts of fogger (he recommends Seafoam fogger) into the engine where the spark plugs go. Turn the key for about 1-2 seconds. Shoot about 2-3 good squirts into the engine again. Put the spark plugs back in, but not all the way tight so they don't seize up.

 

 

 

 

That's it. Whole process should take about 10 minutes.

Make sure you add Sta-bil Marine or Seafoam to your gas a towards the end of the season to be sure your gas is fully treated. Spray fogging oil into the carb intake while engine is running. You'll have to open the butterflies a little to get it in there. Shut the motor down and remove the spark plugs. Spray the cylinders with fogging oil and turn the motor over a few times but don't start it. Finally, drain AND refill the lower unit. Some people will tell you not to but it's one of those things that's very easily forgotten in the spring and if forgotten it will remind you very quickly. You'll be sitting stalled in the middle of the lake and when u do finally get in there will be a hefty bill for replacement. Overall, it's a really simple process and should only take you 20 minutes to a half a hour at very most. It's not worth it to take it to a dealer and pay the ridiculous cost to have them do it.
