Boat Out of the Water—Bravo Sterndrive
IMPORTANT: Flushing the power package is most effective when performed with the boat and sterndrive out of the water.
IMPORTANT: Flushing is needed if the engine package has been operated in saltwater, brackish water, mineral‑laden water, or
polluted water. For best results, flushing is recommended after each outing and before cold weather and extended storage.
1. Lower the sterndrive to full down/in position.
