Product Description

Key Features
- OEM worm-gear clamp, full reference 54-815504352.
- Verified bellows-attaching application.
- Supersedes 54-32739.
Product Compatibility
Verified uses include the upper exhaust-bellows arrangement on specified MerCruiser 120 engines and the 165 GM 250 cu. in. inline-six exhaust-elbow assembly, 1979–1981, serials 5178959 and above. This number also appears at the U-joint bellows-to-gimbal-housing position on certain older transom assemblies. Match the exact connection.
Installation Notes
Inspect the bellows and clamp seat before replacement. Renew a damaged, corroded or stripped clamp, and position the band and screw housing as shown in the service instructions. Tighten to the specified value without cutting the bellows, then verify component clearance and the serviced connection.
