Understanding the Importance of the Exhaust Manifold
When I first started my journey with my Mercruiser 3.0 engine, I quickly realized the exhaust manifold plays a crucial role in the overall performance of the engine. It directs exhaust gases from the engine out of the boat, and any issues with it can lead to poor performance, overheating, or even engine failure.
