OEM part numbers are used for identification only.

Mercury used different solenoids depending on engine model, serial number and application.

If the solenoid looks the same as yours, this does not always mean it is the correct part.

Please check your original part number and isolated-base configuration before ordering.

Please confirm compatibility before purchase. If unsure, send us your engine model and serial number and we will be happy to check.
