Servicing of marine engines 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 ampli
fi
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.
