Important – Throttle Cam Compatibility
Some Mercury and Mariner 20–25 HP engines have been modified or use different carburettor and throttle linkage arrangements.
Please pay particular attention to the SECOND PRODUCT PHOTO showing the throttle cam.
Before purchasing, compare:
-
Carburettor body and mounting arrangement

Throttle cam shape and position
-
Throttle linkage connections

Original carburettor part number

A matching horsepower and serial number alone does not guarantee compatibility.
