Engine Cooling System
The engine cooling system circulates raw water around com-
ponents and also uses a freshwater heat exchanger on the
engine to reduce engine temperature.
••••
Make sure both engine seawater intake valves (seacocks)
are open before starting the engines and keep the seacocks
open while the engines are running.
••••
The cooling system’s seawater strainers should be checked
for leaks and debris every time you use your yacht. For
instructions on how to clean the seawater strainers, see the
Seawater System section of this Supplement.
Exhaust System
The exhaust system is designed to keep water out of the engines in most sea conditions, however, do not anchor the
stern to sea or shut engines off if waves will flood the exhaust system.
Check all exhaust systems before each use.

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 exhaust systems of both generator and propulsion engine(s).
•
Look for discoloration, water leaks, carbon or stains around joints.
•
Make sure all exhaust clamps are in place and secured.
•
Make sure ventilation systems work and are not obstructed or restricted.
•
Make sure gaps around engine room plumbing, cableways, exhaust system, doors, hatches,
and access panels are minimized to reduce the chance of CO entering the living space(s).
