MSD Marine Distributor Cap
PN 8565
Parts Included:
1 - Cap, PN 8565
2 - 10-32 x 3/4" SHC Screws
Note: If you need to adapt your spark plug wire boots and terminals to fit the towers of the PN 8565
Cap, MSD offers a kit of nine boots and terminals, PN 8849.
This Cap fits MSD Marine Distributors that may also use the Socket style MSD Cap, PN 8564.
Before installing the new cap, note the location of the spark plug wires. It is a good idea to mark the
location of one wire before removing it while leaving the other wires connected to the old cap. Install
the new cap by using the two 10-32 x 3/4" socket head cap screws. With the new cap installed, you
can install each wire individually avoiding any confusion.
After installing the spark plug wires, position the retainer over the boots. Align the mounting bosses and
use the supplied 1.5" self-tapping Phillips head screws to hold the retainer in place. It may be necessary
to apply a slight amount of lubricant to the boots to help them seat into the retainer properly.
