A well-functioning exhaust system is essential for maintaining power, efficiency, and longevity in any marine engine. The Mercury Exhaust Manifold Small Block Dry Joint (8M0185794) is designed to deliver smooth exhaust flow while reducing the risk of water intrusion—an issue that can wreak havoc on performance over time. Built for V8 MerCruiser stern drive and inboard engines, including 305, 350, and 377 cubic inch models from 2002 onward, this heavy-duty manifold is made to withstand the demanding conditions of marine environments.

Why This Exhaust Manifold Stands Out:

• Dry Joint Technology – Prevents water from leaking into the exhaust system, reducing corrosion and extending engine life.
• Heavy-Duty Cast Iron Build – Coated for superior corrosion resistance, ensuring durability in saltwater and freshwater applications.
• Versatile Installation – Designed for port or starboard placement, making it a reliable replacement option for a wide range of MerCruiser engines.

Ideal For:

• Routine maintenance to replace a worn or corroded manifold before performance suffers.
• Full engine rebuilds or upgrades where reliability and long-term performance matter.

A failing exhaust manifold can lead to overheating, loss of power, and even severe engine damage. The Mercury Exhaust Manifold Small Block Dry Joint (8M0185794) ensures efficient exhaust flow, keeping your engine running strong for years to come.
