Winterizing?? Who does that??
Well this is the way I do it. I am sure I will miss something and others will have different things they do. But works for me!
First I like to treat the gas before my last trip so that the stablizer gets thur the whole system.
Well i have a 175 Yamaha and what I do is give it a good washing,
Then I change all the lower unit oil!!!! Including new seals on the screws !!!
Grease all greaseable areas.
I pull the steering cable out every fall clean and grease and wrap till spring. In spring I clean the tube and grease well and reinstall the cable. This keeps the cable from ever getting rusted in the tube over the winter!
This is my option as once you have a frozen cable in the tube, you will never want it again!!!
Run the motor with freash water and run for a little while to give it a good flushing!
Remove the Carb covers, Then while it is running spray the Fog oil as directed in to the carbs, it will smoke like the #^&#^&#^&#^&ens!! But this is what you want!!
Shut it down and your done!! Leave the motor in the down postiton for the whole winter so no water stays in the head.
I also check for nicks in the paint and repair as needed to stop rust and corrsion. Check all zinc's replace as needed.
Good luck!!
