Shop our selection of Mercury diesel TDI 4.2L parts, and as an authorized Mercury dealer we'll save you up to 80% off retail.
Our exploded parts diagrams are the key to finding your Mercury 4.2L V8 diesel parts. Check them out to find engine components; wiring harnesses, ignition parts, and everything else that goes into keeping your motor running. Once you find your parts, keep those diagrams handy for when you're taking things apart and putting them back together again. For the parts you can't find, contact our customer service team by live chat or by phone and let us help you find the parts you need to get back on the water.
