Unlike automotive engines, all marine inboards have exhaust risers that feature a water induction elbow. Located behind the engine’s coolant reservoir, the manifold elbow is a critical component to prevent water from entering the engine. It is also a target for corrosion and must be examined frequently and replaced as needed. Sierra, a leading aftermarket manufacturer offers the 18-1976-2 MerCruiser Manifold Elbow which is compatible with most MerCruiser V6 and V8 applications, 7 degree (4" O.D. Riser). This component is recommended for saltwater applications, additional product information follows:
