PROTECTING 
YOUR 
INVESTMENT 
Care at the factory during assembly and thorough testing have 
resulted in a WESTERBEKE engine capable 
of 
many thousands 
of 
hours 
of 
dependable service. However, the manufacturer can-
not control how 
or 
where the engine is installed in the vessel or 
the manner in which the unit is operated and serviced in the field. 
This is up to the buyer/owner-operator. 
NOTE: 
Six important steps to ensure a long engine/generator life. 
•  Proper engine installation. 
•  An efficient, well-designed exhaust system that includes 
an 
anti-syphon break to prevent water from entering the engine. 
•  Changing the engine oil every 250 operating hours. 
•  Proper maintenance 
of 
all engine components according to the 
maintenance schedule in this manual. 
•  Use clean, filtered diesel fuel. 
•  Winterize your engine according to the 
LAY-UP 
AND 
RECOMMISSIONING section in this manual.
