Key Features
- Genuine Mercury Marine / Quicksilver OEM plug kit.
- Commonly identified as an Access Hole Plug Kit.
- Mercury describes the kit material as high-density polyethylene engineered to be heat and oil resistant.
- Service bulletin language states the kit contains two plugs, a special swivel shaft nut, and a template for locating access holes.
Engine Compatibility
This plug kit is associated with selected Mercury MerCruiser Alpha One Gen II and Bravo sterndrive / gimbal housing applications. Dealer listings specifically tie it to Alpha and Bravo use, but exact fitment should always be confirmed by drive model and serial number before ordering.
Serial Number Fitment Notice
Please confirm compatibility in the Mercury Parts Catalog by your exact MerCruiser drive serial number before purchase. Mercury’s official catalog is organized by model and serial number for accurate parts lookup.
When This Part Needs Replacement
This kit is typically used when servicing the gimbal housing / swivel shaft access holes, especially when the original plugs are missing, damaged, or when the access holes need to be sealed after service work. Mercury service-bulletin language specifically describes the kit as being available to seal the access holes and support the related installation procedure.
Installation Notes
Install this kit according to the appropriate Mercury MerCruiser service-manual procedure for gimbal ring, swivel shaft, and steering lever removal and installation. Because this is an access-hole sealing kit rather than a universal plug, exact application matching matters.

Parts Desk Insight
Small gimbal-housing parts like this are easy to overlook, but they help finish the job properly after service access work. Using the correct OEM plug kit helps keep the housing sealed the way Mercury intended instead of improvising with generic plugs. This is an inference based on the part’s documented purpose as an access-hole sealing kit.
