Engine Maintenance is a ten-chapter
course that stresses the diagnosis of modern systems, while also teaching
the basics of engine layout and operation.
Gasoline inboards, outboards,
and diesel engines are taught in a way that reinforces the common aspects
of how engines work. Modern engines offer high reliability and good
performance through the use of computerized systems for fuel delivery and
engine timing. Most of these systems are "black boxes" that can no longer
be serviced by weekend mechanics with ordinary tools. The EM course covers
those repairs that do-it-yourselfers can still perform, teaches how to
diagnose problems that might be beyond your ability to fix, and how to
share information with your mechanic so the right repairs get performed.
Engine Maintenance also covers basic mechanical systems such
as drive systems (propellers), steering systems, and engine controls. The
last chapter discusses solutions you might use to problems that could occur
while afloat and away from a repair facility. Gasoline, diesel, and
outboard engines are treated independently in this chapter.
