The Shields Marine Series 200 Reinforced Wet Exhaust Hose SHI-200-1-1/2 is a heavy-wall marine hose designed for straight wet exhaust connections and engine water circulation applications. Its softwall, fabric-reinforced construction is built for installations where wire reinforcement is not required and the hose run does not involve tight bends or suction conditions.
With a 1-1/2 in. inside diameter, this hose is suitable for compatible wet exhaust, cooling water, and engine discharge plumbing where the vessel layout and engine specifications call for reinforced marine exhaust hose.

System Compatibility
Common application context includes marine installations requiring 1-1/2 in. reinforced wet exhaust hose, including:
- Straight wet exhaust hose connections between exhaust components.
- Engine cooling water circulation lines.
- Heat exchanger discharge plumbing.
- Water-cooled exhaust outlet connections where softwall hose is specified.
- Pleasure craft engine compartment hose replacement where the installation calls for Type Certified wet exhaust hose.
Use this hose only where the engine manufacturer, vessel layout, hose diameter, temperature requirement, routing path, and exhaust/cooling system design confirm compatibility.
Fitment Notice
Confirm hose inside diameter, outside clearance, run length, bend radius, clamp style, exhaust temperature rating, and installation layout before ordering. This hose is intended for relatively straight runs where wire reinforcement is not needed.
For tight bends, suction-side plumbing, or installations where hose collapse may occur, use the correct wire-reinforced marine hose specified for the application.
When This Hose Needs Replacement
Replace wet exhaust hose if it is cracked, soft, swollen, blistered, oil-soaked, heat-damaged, delaminated, leaking, chafed, flattened, or showing signs of internal collapse. Replacement is also recommended during exhaust system repairs, engine repowers, heat exchanger service, or when older hose no longer meets the system’s safety requirements.
A failing wet exhaust hose can allow exhaust gas, cooling water, or seawater into the bilge and should be addressed before returning the vessel to service.
Installation Notes
Cut the hose cleanly to length and route it without sharp bends, kinks, abrasion points, or contact with hot dry exhaust surfaces. Use properly sized marine-grade hose clamps and confirm the hose is fully seated on the fitting before tightening.
Support longer hose runs as needed and avoid over-tightening clamps to the point of cutting into the rubber. After installation, run the engine and inspect the hose, clamps, and fittings for leaks, movement, heat stress, or seepage.

Parts Desk Insight
This is a softwall reinforced wet exhaust hose, so it is best suited to straight runs where the hose does not need wire support. The important checks are the 1-1/2 in. inside diameter, routing path, bend requirement, and clamp fit. For any curved or suction-sensitive installation, confirm whether a wire-reinforced hose is required before cutting and installing.
