Trident Marine 4" ID Blue Silicone Molded Wet Exhaust Hump w/4 T-Bolt Clamp

The Trident Marine 4" ID Blue Silicone Molded Wet Exhaust Hump with 4 T-Bolt Clamp is engineered for marine propulsion systems requiring reliable, flexible exhaust connectivity in high-temperature wet environments. Designed for recreational and commercial marine vessels, this hump hose bridges the critical connection between engine exhaust manifolds and through-hull seawater cooling systems. Built to handle the unique demands of saltwater operation, this component absorbs engine vibration, accommodates misalignment, and maintains system integrity under sustained thermal and mechanical stress.

This wet exhaust hump is constructed from premium marine-grade silicone and rubber compounds selected for superior heat tolerance and flexibility compared to rigid metal piping. The molded design provides engineered flex points that absorb vibration transmitted from engine movement and shaft rotation, reducing fatigue on adjacent fittings and reducing noise transfer throughout the vessel hull. The 4-inch inner diameter accommodates standard marine exhaust flows, while the included 4 T-Bolt clamps ensure positive, corrosion-resistant mechanical fastening without reliance on band clamps that can loosen over time. This configuration is proven to withstand elevated temperatures inherent to wet exhaust systems while remaining flexible enough to compensate for engine sag and hull flexing.

Marine mechanics and vessel operators benefit from this hump hose when replacing worn or damaged exhaust sections on inboard engines with seawater cooling systems. Installation requires standard marine plumbing tools and takes minimal time compared to rigid pipe fabrication. The compact 7 x 7 x 7 inch footprint accommodates tight engine room geometries on cruisers, fishing boats, and commercial workboats. Ensure 4-inch hose barb or flange compatibility on both exhaust manifold and through-hull connection points before ordering; this hump is designed as a bridge component, not an intake line.
