Insist on ONLY Mercruiser Factory Parts!

Mercruiser Distributors come in various styles.

as well as the latest Thunderbolt and Delco Systems.

Distributor replacement should only be done by an experienced
Mercruiser Technition who has the proper tools.

Improper timing could lead to serious engine damage!

All of our Mercruiser Distributor Assemblies come complete
