The flange is engineered to meet the exacting specifications of Mercury-Mercruiser engines, ensuring a perfect fit and optimal performance.

Another important aspect of this exhaust manifold is its compatibility with various Mercury-Mercruiser engine models. Specifically, it is designed to work with 3.0L, 3.4L, 3.6L, and 4.3L engines, making it a versatile option for a range of watercraft applications.

In summary, the Mercury 8M0099070 Exhaust Manifold is a high-performance and durable component designed to deliver optimal exhaust flow and reduced back pressure for your marine engine.
