Description

Mercury MerCruiser Quicksilver 29081, commonly listed as 10-29081, is a genuine OEM screw identified by current Mercury dealer sources as SCREW (.437-14 x 1.250). Because current seller descriptions vary around the application wording, the SKU itself is the safest source of truth here, and the strongest confirmed description is the Mercury hardware specification and part number.

Engine Compatibility

Current where-used references show 29081 across a broad mix of older Mercury and MerCruiser applications, including Mark 75A/78/78A, Merc 200, Merc 600, 300 Tempest GM 350 V-8, 330 GM 454 V-8, 370/400/440 TRS GM 454 V-8, 460 TRS GM 482 V-8, 420 GM 454 V-8, 425 GM 454 V-8 / Gen. V, 465 GM 502 V-8 / Gen. V, and Bravo X One / Two / Three assemblies. The strongest supportable fitment is by exact serial-number-based parts diagram rather than by model family alone, because this screw appears in many different Mercury and MerCruiser assemblies.

Serial Number Fitment Notice

Verify fitment by exact engine or drive serial number and the correct parts diagram before ordering. With a hardware item like 29081, the size may be right while the intended mounting location differs, so serial-based confirmation is the safest way to match it correctly. That caution is supported by the unusually broad current where-used coverage shown by Mercury dealers.

When This Part Needs Replacement

Replace this screw when the original is corroded, stripped, damaged, missing, or no longer holds torque correctly in the assembly being serviced. Because 29081 is an OEM hardware item used across many Mercury and MerCruiser systems, replacing worn original fasteners during related service can help avoid repeat labor from compromised threads or weakened hardware. This replacement guidance is a practical service inference based on its documented use as a Mercury OEM service fastener.

Installation Notes

Confirm the exact application in the correct Mercury parts breakdown before installation. Current sources consistently identify this part by its Mercury number and dimensions, .437-14 x 1.250, so matching both the SKU and the assembly callout is the right approach during service. One current OEM-oriented catalog also labels it as screw, anodic plate to gear housing (1 1/4″), which is another reason to verify the exact diagram before installation instead of relying on a generic name alone.

Alternate/Superseded Part Numbers

Current Mercury dealer references show 57900 as the earlier superseded OEM number for 29081. Older catalog wording tied 57900 to a specific legacy application description, but the current active Mercury replacement is 29081.

Parts Desk Insight

This is a good example of why the SKU should lead the listing. Part 29081 is clearly a Mercury OEM screw, but current catalogs attach different application descriptions to it, so the safer move is to trust the SKU and confirm the exact serial-number-based diagram instead of overcommitting to one description line.
