Exhaust manifolds and risers on inboard engines are large metal castings that transport hot exhaust gases away from the engine. If the Engine is high enough above the waterline, the riser may slope down from the end of the manifold. The exhaust hose is attached to the riser or elbow's aft end. The issue is that manifolds and risers don't have an expiration date or a warning light to alert you when they're about to fail. When they fail, they have the potential to destroy the engine.common,
