Sierra 18-2745 OMC Exhaust Hose 912374

Upgrade Your OMC Engine with a Reliable Exhaust Hose Replacement

Keeping your outboard or sterndrive engine running smoothly means paying close attention to critical components like the exhaust hose. Over time, exposure to hot gases, water, and vibration can lead to cracks, swelling, or deterioration, potentially causing leaks that affect performance and safety. This precision-engineered replacement restores proper exhaust flow, reduces backpressure, and helps prevent overheating issues common in marine environments.

Crafted from high-grade reinforced rubber, it withstands the rigors of saltwater and freshwater use while maintaining flexibility for easy routing in tight engine compartments. Boat owners appreciate how it fits seamlessly into OMC systems, delivering OEM-level performance without the premium cost.

Perfect Fit for Popular OMC Models

Designed as a direct swap for specific OMC applications, this hose ensures compatibility with a range of engines from the brand's storied lineup. It matches the original dimensions and bend radius, eliminating guesswork during installation. Mechanics often recommend it for models where exhaust integrity is paramount, helping maintain optimal cooling and power output.

• Precise inner and outer diameters for leak-free connections
• Reinforced construction resists collapse under vacuum or pressure
• Heat-resistant materials handle exhaust temperatures up to demanding levels

Whether you're prepping for a season of fishing, cruising, or racing, swapping in this hose can extend engine life and boost reliability on the water.

Key Benefits for Marine Enthusiasts and Pros

Beyond basic replacement, this hose offers tangible advantages that enhance your boating experience:

• Durability in Harsh Conditions: UV-stabilized and oil-resistant to fend off degradation from fuel spills or sun exposure.
• Improved Engine Efficiency: Smooth interior walls minimize restrictions, promoting better scavenging and horsepower retention.
• Easy Maintenance Access: Flexible design allows for straightforward inspection and cleaning during routine service.
• Cost-Effective Reliability: Provides factory-spec performance at a fraction of dealer prices, ideal for DIYers and fleet operators.

Many users report quieter operation and reduced vibration after installation, as the hose absorbs engine pulses effectively.

Step-by-Step Installation Guide

Replacing your exhaust hose doesn't require a full teardown. With basic tools, you can complete the job in under an hour:

1. Disconnect the battery and allow the engine to cool completely.
2. Loosen clamps at both ends of the old hose and carefully remove it, noting the routing path.
3. Clean mating surfaces on manifolds and transom fittings to ensure a secure seal.
4. Position the new hose, aligning ends properly, and secure with marine-grade stainless clamps.
5. Double-check for kinks or tight bends, then test-run the engine on muffs before hitting the water.

Pro tip: Apply a thin layer of silicone lubricant to the inner surface for easier fitting over barbed connections, and always torque clamps evenly to avoid slippage.

Long-Term Care to Maximize Lifespan

To get the most out of your investment, incorporate these habits into your maintenance routine:

• Inspect annually for abrasions, bulges, or softness, especially after heavy use.
• Flush the engine with fresh water after saltwater runs to minimize corrosion buildup.
• Avoid dry-running the engine, as it accelerates hose wear from heat.
• Replace adjacent bellows or gaskets if showing age to prevent system-wide failures.

Regular checks can spot issues early, saving you from costly repairs down the line.
