Turbocharger
Inspect the compressor (blower) as listedin the service
schedule for buildup of carbon residue. An authorized
service dealer, using Yanmar Service Manuals, must
perform all other turbocharger inspection and service
describedintheserviceschedule. SeeFigure 3-10and

Figure 3-10. Turbocharger Inspection
1. Remove breather hose from air intake silencer
connector, if equipped.
2. Loosen hose clamp on air intake silencer and
remove air intake silencer.
3. Inspect compressor (blower) housing and impeller
(blower wheel) for buildup of carbon residue. If the
compressor requires cleaning, contact an
authorized Kohler service distributor/dealer, who
should use a Yanmar approved turbocharger
cleaner.
4. Place air intake silencer over turbocharger
compressor housing inlet and tighten clamp.
Direct the air intake silencer duct down and away
from the engine.
5. Attach breather hose to air intake silencer
connector, if equipped.
Servicing Mixing Elbow
1. Check inside mixing elbow for carbon buildup and
corrosion.
2. Remove carbon buildup with a wire brush.
3. Inspect exhaust manifold mounting threads for
cracking and corrosion. The mixing elbow
combines high temperature exhaust and cooling
seawater. When exposed to engine vibration, the
mixture of exhaust and seawater can cause rapid
deterioration and failure in an improperly
maintained exhaust system.
4. Replace damaged mixing elbow or other exhaust
components to prevent engine exhaust (carbon
monoxide) leakage.
