Serial Number Fitment Notice
Verify fitment by exact engine serial number and the correct MerCruiser parts diagram before ordering. This plug appears across multiple MerCruiser engine families, so serial-based confirmation is the safest way to match the correct service location and replacement number.
When This Part Needs Replacement
Replace this plug when the original is corroded, damaged, rounded, leaking, or removed during service and no longer seals correctly. Current cross-reference sources also commonly associate this part with 3/4-14 pipe plug service in MerCruiser exhaust-related applications, so condition and thread integrity matter more than appearance alone.
Installation Notes
Install this part only after confirming the correct MerCruiser service location and thread size. The strongest current sizing support is .750-14 / 3/4"-14 NPT, so the plug should be matched to the correct threaded port in the applicable Mercury or MerCruiser assembly.
Alternate/Superseded Part Numbers
Current supersession references show 416223 as the active replacement for 41622. Additional related or superseded references currently associated with this plug include 33198A1, 33198, 416222, and 46754.
Parts Desk Insight
For a part like this, the important match is the thread size and exact service location. Small pipe plugs can look interchangeable, but confirming the serial-number-based parts diagram first is the better way to avoid getting the wrong plug for the job.
