- Factory-spec material and finish
- Direct replacement for the original assembly position
Fitment & Application
Use this clamp where the Mercury or MerCruiser parts diagram specifies part number 12078 or 54-12078. Fitment can vary by engine model, drive type, and serial number range — always confirm against your specific parts diagram before ordering.
When to Replace
Replace when the clamp is corroded, deformed, cracked, or has been removed from a critical assembly during service and cannot be safely reused. Clamps in cooling, fuel, and exhaust circuits should be inspected at every service interval.
Installation Notes
Verify the clamp diameter, band width, and material against the diagram position before installation. Follow the Mercury service manual for torque specifications and any reuse restrictions. Do not substitute a generic clamp in a position that specifies an OEM part.

Parts Desk Insights
Best use case: This clamp is the right choice when the Mercury or MerCruiser parts diagram calls out 54-12078 specifically and an OEM-spec fit is required. Generic hose clamps are often close in size but differ in band width, material, and end-stop design — in fuel, cooling, or exhaust positions, that difference matters. Order by diagram position and confirm the part number matches before installation.
