Industrial 387057 Throttle Shaft And Gear Assembly

The OMC 387057 Throttle Shaft and Gear Assembly is a direct replacement part engineered specifically for servicing the power transmission mechanisms found in vintage Outboard Marine Corporation outboard motors. This mechanical unit links the operator's hand controls to the engine's fuel intake valves, ensuring that manual throttle inputs translate directly into precise fuel meter adjustments, which maintains optimal engine performance across the full operating range intended for this industrial design. Operators utilizing older marine vessels often find this component necessary when original shafts develop excessive play or gear teeth strip due to prolonged wear, effectively correcting issues such as delayed response or inconsistent idle stability. Using the verified part designation 387057 helps buyers confirm exact fitment for their rebuild projects, eliminating compatibility mismatches that occur with generic aftermarket substitutes lacking the original manufacturing tolerances.
