About This Part
The 47462 / 10-47462 is a genuine Mercury Marine / MerCruiser OEM mounting screw with a 7/16-14 UNC coarse thread and a length of 1.250 in. / 31.8 mm. Mercury uses this fastener in multiple MerCruiser engine and drivetrain mounting assemblies including mounting brackets, transmission mounts, accessory-support brackets, and brace locations. Because the same part number appears across several different diagrams, fitment must be confirmed by the specific assembly and diagram item number — not engine family alone.
Compatible Applications
Confirm the exact assembly, diagram position, and item number before ordering. Documented applications include:
- Mounting bracket to transmission on selected MerCruiser assemblies — used with lock washer 32993
- Engine accessory mounting and brace assemblies
- Alternator-support and accessory-drive bracket locations
- Other installations where the Mercury parts diagram specifically calls for 47462
Fitment Notice
Mercury uses many visually similar coarse-thread mounting screws across its engine and drivetrain product range. The key specifications for this fastener are 7/16-14 UNC thread and 1.250 in. / 31.8 mm length. Do not substitute a 3/8-16 or different-length fastener — an incorrect length can result in bottoming out short of clamping load or insufficient thread engagement in the mating hole.
When to Replace
- Threads are stripped, stretched, or cross-threaded
- The screw head is rounded or otherwise damaged
- Heavy corrosion is present on the shank or threads
- The fastener has been bent or the mounting joint has loosened repeatedly
- The applicable service procedure specifies fastener replacement
Inspect the mating threads in the bracket or transmission housing, and replace the associated washer or lock washer at the same time.
Installation Notes
- Clean the mating threads and confirm they are undamaged before installation
- Use the correct washer or lock washer specified in the Mercury parts diagram for the specific assembly
- Start the screw by hand to avoid cross-threading
- Torque to the specification in the applicable Mercury service manual for the assembly — do not guess torque on structural mounting fasteners
- Common associated hardware includes 32993 lock washer, 31263 washer, and 22248 washer depending on the exact assembly

Parts Desk Insights
The most reliable way to order 47462 is by its hardware spec: 7/16-14 × 1-1/4 in. Mercury uses it across more than one mounting location, so the engine model alone won’t tell you if this is the right screw — you need the diagram and item position. The most common mix-up is ordering a 3/8-16 screw because the head looks the same, or grabbing the 1-1/2 in. 47651 because it was “close enough” in the parts bin. Neither will torque correctly in the original location. If you’re replacing a stripped mounting fastener and you still have the old screw, measure the thread diameter and length before ordering.
