PRODUCT OVERVIEW

YANMAR 4JH COMMON
RAIL SERIES FEATURES
AND APPLICATIONS
The 4JH common rail series are
four-stroke diesel engines equipped with
direct injection common rail system and
with liquid coolant systems.
The 4JH45, 4JH57 is 4-cylinder and
naturally aspirated.
The 4JH80, 4JH110 is 4-cylinder and
turbocharged with an air cooler.
The engines are equipped with a marine
gear or sail drive unit.
These engines are designed for pleasure
craft use.
It is recommended that new vessels be
propped so the engines can operate at 50
-1
to 100 min above the fuel stop power
engine speed to allow for some added
weight and hull resistance.
Failure to do so can lead to reduced vessel
performance, lead to increased smoke
levels and cause permanent damage to
your engine.
