Exhaust System

Always consider the sea conditions before anchoring or shutting Off the engines.

The exhaust system is designed to keep seawater out of the engines in most sea conditions.

However, do not anchor the stern to sea or shut the engines Off if high seas might flood the exhaust system.

CARBON MONOXIDE POISONING HAZARD!  

Leaking engine and/or generator exhaust is a source of dangerous carbon 
monoxide gas (CO). 

Check ALL exhaust systems BEFORE each trip.

Look for leaks in the exhaust systems of the engines and the generator.

Look for discoloration, water leaks, carbon or stains around ALL joints.

Make sure ALL of the exhaust clamps are in place and secured.

Make sure the ventilation systems work and are NOT obstructed or restricted.

To reduce the chance of CO entering the living spaces, fill any gaps around engine room 
plumbing, cableways, exhaust systems, doors, hatches, and access panels.

Read the Carbon Monoxide (CO) section of Chapter 1 in this Owner’s Manual.

DANGER !
