Mercruiser Distributor Caps come in various styles.

We carry the older conventional caps
as well as the latest Thunderbolt and Delco Caps.

Caps tend to get a corrosion type of build-up on
the inside of the cap on the electrodes.
This will effect performance and mileage.

Improper timing could lead to serious engine damage!
Always properly check your timing after replacing a cap.
Remember to make sure you have your firing order right!
Opposite rotation engines have a different firing order.
