The exhaust system for each engine consists of an exhaust manifold, exhaust piping,
and the exhaust hoses used to vent the exhaust to the atmosphere . Carbon monoxide
may escape and endanger everyone on board if the exhaust system contains leaks or
obstructions, or has any other problem that prevents it from venting exhaust properly .
Check the exhaust system regularly for proper operation . Change in engine noise could
indicate an exhaust system problem, and should immediately be investigated .

FUEL ShUT-OFF VALVES
Fuel supply shut-off valves are located on top of the fuel tanks, in the center of the
engine room, forward the engine room access hatch . THE VALVES MUST BE OPEN
WHILE OPERATING THE ENGINES .
FUEL TANK VENTS
Each fuel tank is vented overboard . During fueling, air is displaced from inside the tanks
and the air escapes through the vents . However, when the engines are running, air
enters the fuel tanks through the vents to displace the fuel being used .
