Electronic Manuals are great but when you need to work on your motor you need a real paper manual in front of you to reference. Don't get your computer covered with grease and quit running in and out of the house to look at that one drawing. Get a real manual you can have right in front of you while you work at a fraction of the price of a new one.
Listed here is a NEW Original Mercury Shop Manual. The same exact one the guys at your factory dealer use. If you have a problem you can call your local shop and tell the mechanic to turn right to the same page you are on.
