🔌 Function

Supplies cooling water to the exhaust riser/elbow so exhaust temperature remains controlled before discharge.

⚠️ Common Signs of Failure

• Water leak around the riser
• Steam or elevated exhaust temperature
• Hose heat damage or delamination
• Restricted seawater flow
• Salt deposits at the hose ends

🛠️ Service Notes

• Fit hoses only to clean, sound spigots — take off old rubber, scale and corrosion, and renew the spigot or pipe if it is pitted, because no clamp will seal a rough sealing face
• Push the hose fully home so the clamp sits behind the bead or barb rather than over the end of the spigot, and fit new clamps whenever a hose is renewed
• Let the hose follow its natural bend with no kinks and no tension on either connection, clear of hot surfaces and moving parts, with chafe protection wherever it passes a bracket, edge or bulkhead
• Use the correct grade of hose for the duty, and clamp to the standard the installation demands — twin clamps are normal practice on seawater and fuel connections below the waterline
• Refill, vent and run the engine, then check every joint hot and cold and recheck the clamps after the first running period as the hose beds down
