The Sierra 47-2613 Cobra Outdrive Mounting Gasket Set is a complete sealing kit for the outdrive mounting interface on OMC Cobra sterndrive systems. This kit provides everything needed to properly seal the outdrive to the transom housing during installation or service, preventing water intrusion and gear oil leaks at the mounting face.
Kit Contents
- 1 × Gasket (2918)
- 1 × Seal (2996)
- 2 × O-Rings (7153)
Key Features
- Complete mounting gasket set — all sealing components included in one kit
- Designed specifically for OMC Cobra sterndrive outdrive mounting applications
- Sierra marine-grade materials rated for saltwater and freshwater use
- Ensures a leak-free seal between the outdrive and transom plate
Best Use Case
Use this kit any time the outdrive is removed from an OMC Cobra sterndrive — whether for seasonal service, bellows replacement, or drive repair. All gaskets and seals at the mounting face should be replaced as a set whenever the drive is pulled; reusing old seals is the leading cause of water intrusion into the bilge on Cobra-equipped boats.
Parts Desk Insights
This kit is specific to the OMC Cobra outdrive mounting interface — confirm your drive model before ordering, as other OMC and Volvo sterndrive variants use different gasket sets. If you're doing a full outdrive service, also consider replacing the exhaust bellows: OMC Cobra Exhaust Bellows (47-1074) and OMC Cobra Exhaust Bellows (47-2764). For corrosion protection on your Cobra drive, see the Martyr OMC Cobra Anode Kit (Aluminum) or Martyr OMC Cobra Anode Kit (Magnesium).
