The servicing of marine engines and generator sets
presents unique problems. In many cases, boats cannot
be moved to a repair facility. Marine engines cannot be
compared to the servicing of automobiles, trucks, or
even farm equipment. Failures often occur in remote
areas far from competent assistance. Marine engines are
taxed far more severely than auto or truck engines;
therefore, maintenance schedules must be adhered to
more strictly. Failures begin with minor problems that
are overlooked and become amplifi ed when not corrected
during routine maintenance.
As operator, it is your obligation to learn about your
equipment and its proper maintenance. This is not a
comprehensive technical service manual. Nor will it make
the reader into an expert mechanic. Its aim is to aid you in
maintaining your unit properly.
