on your engine, transmission, and drive, we urge you to be thoroughly familiar with the procedures described in
this manual. Always read and follow the safety warnings provided in this manual. If you are uncertain about

Engine Exhaust System

Periodically inspect the engine exhaust system. Be sure to check for:
Deteriorated hoses.
Burned hoses.
Loose clamps.
VPA 7748131 English 09-2007

Evidence of water leaks.
Corrosion or blockage in the exhaust manifold
and riser(s).
Check the gasket surface (B), between the exhaust
riser (A) and manifold (C), for damage caused by cor-
rosion. The components should be replaced if the
walls are thin or surface is pitted. Water may leak into
the engine if this joint is damaged. If necessary, see
your authorized dealer for this inspection.
WARNING! Replace damaged or defective
components, and securely tighten all clamps.
Any exhaust leak must be repaired before you
operate your boat. Exhaust leaks release
fumes that can create hazardous conditions
for operator and passengers.
