Buyer Responsibility

Please check your engine model, serial number, mounting style and existing part number before ordering.

Mercury used several different CDI units that can appear almost identical but are not interchangeable.

If the part looks the same as yours, it is not always the correct one for your outboard.

If you are unsure, please send us your engine model and serial number before purchasing and we will be happy to confirm compatibility.
