Product Details
This Bell Housing Installation Gasket Kit is an aftermarket gasket set for servicing the bell housing and transom connection on selected MerCruiser MC-1, R, MR, Alpha One, and Alpha One Gen II sterndrive applications. The kit is intended to replace the sealing components removed during sterndrive or transom-assembly service and to help restore a reliable seal between mating surfaces.
The principal cross-reference for this gasket set is Mercury/MerCruiser 27-94996Q2. Catalog references associate this number with MC-1/R/MR and Alpha One/Alpha One Gen II transom-component applications. Always compare the existing part, drive generation, and serial number before ordering because sterndrive configurations can vary.
- Gasket-set format for bell housing and transom-assembly service.
- Designed for selected MerCruiser MC-1, R, MR, Alpha One, and Alpha One Gen II applications.
- Helps renew sealing surfaces when the sterndrive or related transom components are removed.
- Aftermarket replacement; not manufactured by Mercury/MerCruiser.

- Place the sterndrive in a supported service position and support its weight with suitable equipment.
- Remove the sterndrive or related transom components according to the manufacturer’s service instructions.
- Remove the old gaskets and carefully clean all mating surfaces. Eliminate old gasket material, sealant residue, corrosion, and debris without damaging the surfaces.
- Compare each replacement gasket with the removed component and confirm that it matches the intended location and drive configuration.
- Install the new gaskets and sealing components in their designated positions. Do not use sealant unless the applicable service manual specifically requires it.
- Reassemble the components using the manufacturer’s specified fastener sequence and torque values.
- After reassembly, inspect the transom and bell-housing area for leaks and correct any problem before operating the boat.
Troubleshooting & FAQ
How do I know if this kit fits my MerCruiser drive?
Confirm that your drive is an MC-1, R, MR, Alpha One, or Alpha One Gen II configuration associated with Mercury/MerCruiser part number 27-94996Q2. Check the drive model, serial number, original gasket shape, and service-manual illustrations before ordering. Engine horsepower and stroke alone are not sufficient to confirm fitment.
Is this an OEM Mercury/MerCruiser kit?
No. This is an aftermarket replacement gasket set that cross-references Mercury/MerCruiser 27-94996Q2. Mercury and MerCruiser are referenced only to identify the applicable original part and drive applications.
What are the signs of a failed bell housing gasket?
Possible signs include water entering the bilge near the transom cutout, visible leakage at the sterndrive-to-transom connection, damaged or compressed gasket material, or corrosion and contamination around the mating surfaces. Diagnose the complete assembly before replacing parts.
When should the gaskets be replaced?
Replace sealing components whenever the applicable sterndrive or transom assembly is removed if the service manual calls for new gaskets. Inspect the mating surfaces and related seals during every service operation.
What if the supplied gasket set does not match my original parts?
Do not force or modify a gasket to make it fit. Stop installation and recheck the drive model, serial number, original part number, gasket orientation, and package contents against the applicable service documentation.
Shipping speed and warranty?
Shipping options, delivery estimates, returns, and any applicable product warranty are determined by the order and store policies shown at checkout.
Safety & Important Info
- Verify the drive model, serial number, original gasket profile, and reference number before purchase.
- Do not rely on engine horsepower or stroke alone to determine sterndrive-gasket fitment.
- Use the manufacturer’s service manual for removal procedures, sealing requirements, fastener sequence, and torque specifications.
- Professional installation is recommended when removing or reinstalling a sterndrive or transom assembly.
- This is an aftermarket replacement, not an OEM Mercury/MerCruiser component.
