The Bravo Three (2003 and newer) SERV KIT-300 HRS is a genuine Mercury Marine service kit designed specifically for Bravo Three sterndrive units from 2003 onwards. This 300-hour kit is tailored to deliver complete maintenance for high-performance Bravo Three drives, ensuring peak reliability, cooling efficiency, and long-term durability—especially in saltwater or demanding usage conditions.

At the 300-hour mark, your Bravo Three drive has seen substantial use and deserves more than basic maintenance. That’s where this all-in-one OEM kit comes in. It includes the essential components recommended by Mercury to restore performance and prevent premature wear across your cooling and driveline systems.

Inside the Bravo Three (2003 and newer) SERV KIT-300 HRS, you’ll find high-quality Mercury parts such as the seawater pump impeller and housing, oil seals, shift shaft seals, gear lube drain screw gaskets, o-rings, and gimbal bearing service items (where applicable). These components are engineered for exact fit and long-lasting performance in harsh marine environments.

The water pump impeller and housing are critical to your drive’s cooling system and should be replaced every 300 hours to ensure proper water flow and prevent overheating. Replacing these parts as part of scheduled maintenance helps avoid costly breakdowns and supports consistent engine temperatures under load.

Also included are seals and gaskets that protect the drive from water intrusion and gear oil leaks—two common causes of long-term drive damage. With Bravo Three’s dual-prop design and heavy-duty load handling, proper sealing and lubrication are essential for continued smooth operation.

The kit is designed for convenience and precision—perfect for professional servicing or DIY owners who want to perform a full and correct 300-hour service. By using only genuine Mercury components, you maintain factory standards for performance, durability, and safety, while ensuring warranty compatibility and resale value.

Whether you’re navigating long coastal runs, hauling watersports gear, or cruising inland lakes, the Bravo Three (2003 and newer) SERV KIT-300 HRS provides the peace of mind that comes with knowing your sterndrive is protected, maintained, and ready for more adventure.
