🔌 Function

Carries exhaust gas away from the engine, and on a marine installation also has to keep cooling water and exhaust gas travelling where they are meant to go.

⚠️ Common Signs of Failure

• Water in a cylinder, or an engine that is stiff, hard to start or hydraulically locked after standing
• Rusty water, soot or steam escaping at the riser joint, or a rust-stained exhaust hose and clamp
• Rough running, a knock or a misfire shortly after start-up that then clears
• Overheating or reduced water flow at the outlet as corrosion debris blocks the passages
• Heavy scale or flaking, or material that lifts away with a screwdriver, when the joint is opened

🛠️ Service Notes

• Expect corrosion: strip the riser and look through both the gas passage and the water jacket, and renew a casting that is heavily wasted rather than cleaning it up
• Renew the riser gasket and any blanking plate, studs, nuts or bolts that are corroded, and check the mating faces are flat with a straightedge
• Check the manifold, elbow and exhaust hose at the same time, and satisfy yourself the riser still gives the height and fall needed to keep water out of the engine
• Fit the fixings in the sequence and to the figures in the workshop manual for your engine, then check the exhaust and cooling joints for leaks and confirm correct water discharge with the engine running
• Inspect risers at the interval set for your engine, and more often on a boat used in salt water
