A system designed to replace the original exhaust manifolds on a Mercruiser 4.3 liter engine, often including the manifolds, risers, gaskets, and associated hardware. The purpose is to improve engine performance, extend lifespan, or adapt the engine for different operating conditions. These assemblies provide a route for exhaust gases to exit the engine efficiently.
These kits offer various benefits, such as enhanced corrosion resistance, improved flow characteristics, and potentially increased horsepower. Replacing older, corroded manifolds can prevent exhaust leaks into the engine compartment, a safety hazard. Historically, original equipment manifolds were prone to deterioration, making aftermarket conversions a popular upgrade.
