MerCruiser Bravo Bellows Assembly (8M0062406)

The MerCruiser Bravo Bellows Assembly is a complete replacement kit designed to maintain a watertight seal between your Bravo sterndrive and the transom. It includes all the essential bellows components for your Bravo I, Bravo II, or Bravo III drive system. Over time, bellows are subject to constant movement, exposure to sun, water, fuel, and engine heat—which makes them one of the most important parts to replace regularly in order to avoid major damage.

Keep Water Out. Keep Performance In.

Bellows form the protective, flexible barrier between your drive and the boat’s transom. When functioning properly, they prevent water intrusion into critical areas such as the u-joint cavity, exhaust passage, and shift cable channel. A torn or cracked bellows can quickly lead to severe problems—like rusted u-joints, failed gimbal bearings, hydraulic damage, or even water entering the hull. By replacing worn bellows with this complete assembly, you’re preserving both the safety and efficiency of your boat.

What’s Included in the Bravo Bellows Assembly Kit?

This OEM-equivalent kit includes:

• U-joint bellows – Seals the driveline area and protects the gimbal bearing

• Exhaust bellows – Directs exhaust safely through the transom

• Shift cable bellows – Shields the shift cable from moisture and corrosion

• Bellows clamps – Stainless steel, high-strength

• Installation hardware – All necessary fasteners and gaskets

Everything is precision-fitted to MerCruiser factory specs, ensuring an exact fit and long-lasting performance.

Durable Construction for Marine Conditions

Each bellows component is built from marine-grade, fuel- and UV-resistant rubber to withstand the harshest boating environments. Whether you run in saltwater, freshwater, or a mix of both, these parts are made to hold up season after season. The stainless clamps resist corrosion and provide a tight, leak-free seal.

When to Replace Your Bellows:

• Cracks, tears, or visible aging

• Water in gear lube or bilge

• Excessive driveline noise or vibration

• Routine maintenance every 2–3 years

Don’t wait until there’s a leak—prevention is far cheaper than repair.

Easy Installation for DIY or Pro

This Bravo Bellows Assembly is ideal for do-it-yourself boaters and marine technicians alike. With the right tools and a bit of mechanical know-how, installation can be done in a few hours. It’s perfect for pairing with gimbal bearing replacements or full transom service.
