I'm not sure how popular it is but I found a neat resource for Merc owners. It is: http://www.mercurypartsexpress.com/us/ There are expandable PDF thumbnails that show tech drawings of every single piece of your outboard. Additionally it gives you the part number and a price. There is also a pretty cool prop guide where you type in all your info and it makes some recommendations on prop size. Anybody else know of anything like this for Mercs?
