Water
Water
If your boat is in rough seas and rocking back
and forth. It is possible that the outlet could
become immersed and the exhaust line become flooded.
The high water level plus the surging action caused
by the rocking motion, can result in water entering
the exhaust and flowing to the header.
Then as the boat pitches down in the bow, some of
the water drains into the muffler. Then on into the exhaust
riser, and finally into the cylinders.
Then when there is an attempt at re-starting, there is damage
to the engines, or there is serious corrosion to the critical
parts of the engine.
11.3.2 Engine / Generator Exhaust
Your engine exhaust contains Carbon Monoxide! Be
sure and read the Boating Safety Chapter and know
the dangers and how to avoid them. Carbon Monoxide
will kill you, and in most situations, by the time you
know something is wrong it could be too late. Know
what to look for and what to do in case of neces-
sary action. Inspect your boat’s exhaust system fre-
quently, or have a qualified service technician ser-
vice the system to ensure that there are no leaks.
Always ensure the exhaust clamps are tightened,,
throughout the system.
Keep the necessary tools to perform this action on
hand.

tem to cool, before handling, or making adjustments
to avoid injury.
