there are more important things to worry about
I have outboards I bought new as long as 30 years ago and they still look like they are brand new. Buy some canvas and make a cover for the cowl. Keep it covered except when in use.
Do what I do when I get a new vehical. I take my ball peen hammer and put the first dent in it. That way I don't feel bad when somebody slams a door into it in a parking lot. Just put one little scratch in it and you'll feel better.:laugh:
