What part(s) are you looking for?
Launch the Mercruiser parts catalog from
www.mercurymarine.com and instead of entering the serial number, on the left side of the screen, expand the "Sterndrive" folder and then the "Engines - Gas" or "Drives" folder. You'll find the 5.0 Ford (302) and the 888 drive and you can open the parts catalog. Most times, the part numbers have been superseded so you'll need to run the part numbers by a dealer.
