Installation Guide
- Safety First: Ensure the engine is completely turned off and has had ample time to cool down.
- Locate the Valve: Access the sterndrive's exhaust outlet to locate the old exhaust flap.
- Remove Old Flap: Carefully pry off or pull out the existing flap. It may be brittle, so take care not to let pieces fall into the exhaust housing.
- Clean the Surface: Thoroughly clean the mounting area inside the exhaust housing, removing any debris, corrosion, or old material.
- Install New Flap: Firmly push the new exhaust flap into position until it is seated correctly and securely.
- Final Check: Manually move the flap to ensure it swings freely and returns to its closed position.
Troubleshooting & FAQ
Q: How do I confirm this flap fits my sterndrive?
A: This part is compatible with Volvo Penta 290, 290DP, SP-A through SP-E, and DP-A through DP-C models. The most reliable method is to match the OEM part number 852644 with your existing part or service manual.
Q: What is the purpose of this exhaust flap?
A: It functions as a crucial non-return valve. Its primary job is to prevent water from surging back into the engine's exhaust system, especially when the boat is stationary in the water or decelerating quickly.
Q: What are the signs that my old exhaust flap needs replacing?
A: Signs of failure include visible cracks, stiffness, or brittleness in the material. If the flap is stuck open, it can allow water into the engine, while a flap stuck closed can restrict exhaust flow and harm performance. Regular visual inspection is recommended.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
