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 main-
tenance.
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.
