Yanmar 4LHA-HTP Operation Manual page 266

FORWARD
This service manual has been compiled for engineers engaged in sales
service, inspection and maintenance. Accordingly, descriptions of the
construction and functions of the engine are emphasized in this manual
while items which should already be common knowledge are omitted.
One characteristic of a marine diesel engine is that its performance in a
vessel is governed by its applicability to the vessel's hull construction
and its steering system.
Engine installation, fitting out and propeller selection have a substantial
effect on the performance of the engine and the vessel. Moreover, when
the engine runs unevenly or when trouble occurs, it is essential to check
a wide range,of operating conditions—such as installation on the hull
and suitability of the ship's piping and propeller—and not just the engine
itself. To get maximum performance from this engine, you should com-
pletely understand its functions, construction and capabilities, as well as
proper use and sen/icing.
Use this manual as a handy reference in daily inspection and maninte-
nance.and as a text for engineering guidance.
