EVERY 250 OPERATING HOURS OR YEARLY
Hoses
•1gnltlon Timing

•spark Plugs
Engine hoses should be firm and tight. Replace if hoses become spongy, brittle or
delaminated. Check and tighten all hose clamps as needed.
Check timing and adjust
as
needed.

Check vibration isolators, brackets and mounting hardware. Replace
as
needed.
Heat Exchanger
Mechanical Governor
Open heat exchanger and cap(s) and clean out debris. Replace gasket and 0-rings
if
needed.

Change governor oil.
I
EVERY 500 OPERATING HOURS OR YEARLY
Raw Water Pump Remove the pump cover and inspect the pump assembly for wear, especially cam and
wear
plates. Replace the impeller and gasket. Lubricate the impener at re-assembly.
•Exhaust
System catalyst

EVERY 500 OPERATING HOURS OR EVERY TWO YEARS
Ignition Wires
•Coolant
System
Inspect and/or replace. See Data below.
*
Inspect for deterioration. Inspect resistance.
Drain, flush and re-fill the cooling system
with
appropriate antifreeze mix. Replace the
thermostat and coolant pressure cap.
·-------------~·
•valve Clearances
Adjust
valves. (Incorrect varve clearance wiH result in poor engine performance.
*starter Motor Check solenoid and motor for corrosion. Remove and lubricate. Clean and lubricate the
starter motor pinion drive.
EVERY 1000 OPERATING HOURS OR OR EVERY FIVE YEARS
•Engine Timing Belt
Inspect timing belt. Replace as needed. Failure
to
replace belt
can
result in severe engine
damage.
Heat Exchanger
Cylinder Head Bolts
Remove the heat exchanger for professional cleaning and pressure testing.
Re-torque bolts (engine cold). Adjust valves after re-torque.
NOTE: Keep the engine surface clean. Dirt and oil will inhibit the engine's ability to remain cool.
*WESTERBEKE recommends this service be performed by an knowledgeable mechanic.
*CATALYIC CONVERTER
ADDED TO PRODUCTION MODELS .... ( Date Code 0608 )
A Catalvtic Converter has been installed on the engine's
exhaust to reduce exhaust emissions and to conform with

Every 500 operating hours a visual inspection of the
~
converter should be performed. Remove the converter

assembly from the exhaust manifold and inspect the internal
part for damage, carbon build-up, or soot deposits. If light
is not "tisible through the element, replace the converter.
The complete assembly with housing must be replaced. The

is not available separately.
NOTE: Signs that the
