The Mercury MerCruiser Quicksilver 43242T09 is a genuine Mercury Marine OEM accelerator throttle cable used on select small Mercury and Mariner outboard throttle control assemblies. This internal cable transfers throttle movement from the tiller handle, steering handle assembly, or related linkage point to the engine throttle arm, helping provide smooth throttle response and proper return through the operating range. It should be used where the Mercury parts diagram specifically calls for 43242T09.
Key Features
- Genuine Mercury Marine factory OEM accelerator throttle cable.
- Mercury/MerCruiser part number: 43242T09.
- Mechanical throttle-linkage cable for select small Mercury and Mariner outboard applications.
- Used in throttle handle, steering handle, carburetor linkage, or engine-mounted throttle control areas where specified by diagram.
- Helps restore smooth throttle movement when the original cable is stretched, frayed, sticky, or damaged.
- Correct OEM cable routing and length are important for full throttle travel and proper return to idle.
Engine Compatibility
Common application groups include select Mercury and Mariner small-displacement outboards by serial number and control configuration, including:
- 6 HP outboard applications where specified
- 8 HP outboard applications where specified
- 9.9 HP FourStroke applications where specified
- 15 HP FourStroke applications where specified
- XR10 applications where specified
- 10 Magnum applications where specified
- Select tiller-handle, steering-handle, and internal throttle linkage assemblies that call for 43242T09
Use this cable only where the Mercury parts diagram lists 43242T09 for the exact engine model, serial range, and throttle control configuration.
Serial Number Fitment Notice
Confirm fitment by engine serial number, horsepower, steering/tiller handle configuration, and exact throttle linkage diagram before ordering. Small Mercury and Mariner outboards can use different throttle cables depending on model year, control style, handle design, carburetor linkage, and bracket layout.
When This Part Needs Replacement
Replace this throttle cable if the twist grip or throttle lever feels stiff, sticky, uneven, or slow to return. It should also be replaced if the inner cable is frayed, stretched, kinked, corroded, broken, or if the engine does not reach the correct throttle range after proper adjustment. Any throttle cable that binds or fails to return smoothly should be serviced before operation.
Installation Notes
Route the cable exactly as shown in the Mercury service diagram to avoid tight bends, rubbing, or interference with the steering handle and throttle linkage. Inspect the throttle arm, return spring, cable retainers, clips, adjusters, and carburetor linkage while the cable is being replaced. After installation, verify smooth movement from idle to full throttle and confirm the throttle returns fully to idle according to the Mercury service manual.

Parts Desk Insight
Throttle cables should be matched by part number and handle configuration, not just horsepower. A cable with the wrong length, end fitting, or routing path can limit throttle travel, create binding, or prevent the engine from returning cleanly to idle.
