Engine Compatibility

The strongest supportable fitment for 8M0112749 is older Mercury MerCruiser sterndrive and engine applications carried forward from superseded part 30617A2. Current where-used references for that superseded part show coverage across older MerCruiser engine families including 120/140, 160, 165, 228, 233, 250, 260, 470, 485, 888, and 898, plus R/MR/Alpha One sterndrive, R/MR/Alpha One transom assembly, Alpha One SS, and SSM II/III/IV/V applications. The safest match is by exact serial-number-based parts diagram rather than by engine family name alone.

Serial Number Fitment Notice

Verify fitment by exact engine or drive serial number and the correct parts diagram before ordering. With 8M0112749, the safest match is the precise assembly callout because the current active SKU is broad while the superseded where-used history spans many older MerCruiser engine and stern drive platforms.

When This Part Needs Replacement

This bushing assembly is typically replaced when the original bushing is worn, loose, leaking at the seal, or damaged during teardown. Because one current dealer listing confirms the assembly includes an oil seal, renewing the complete assembly during related service is often the better move than reusing an aged sealing surface. This service guidance is a practical inference supported by the SKU’s assembly-level description and included seal note.

Installation Notes

Install 8M0112749 only after confirming the correct Mercury MerCruiser parts diagram for the engine, drive, or transom assembly being serviced. Current supersession references show this active number replacing an older part used across multiple MerCruiser platforms, so diagram-level confirmation is the right approach before disassembly or reassembly.

Alternate/Superseded Part Numbers

Current sources connect 30617A2 and 30617A1 to active Mercury part number 8M0112749.

Parts Desk Insight

With an assembly part like this, the exact diagram position matters more than the generic name. Matching 8M0112749 by serial number is the safer move, especially since the active SKU replaces older MerCruiser numbers used across a wide range of legacy engine and stern drive applications.
