PRODUCT OVERVIEW
YANMAR GM FEATURES
AND APPLICATIONS
The GM series are four-stroke swirl
pre-combustion chamber diesel engines
equipped with direct seawater cooling
systems.
The 1GM10 is a naturally aspirated
1-cylinder engine equipped with a KM2P
marine gear.
The 1GM10C is a naturally aspirated
1-cylinder engine equipped with an SD20
sail-drive.
The 1GM10V is a naturally aspirated
1-cylinder engine equipped with a KM3V
marine gear.
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 100
to 200 min
-1
above the Maximum Rated
Power Output engine speed (3700 to
3800) to allow for some added weight and
hull resistance. The engine must be able to
reach the Maximum Rated Power Output
(3600 min
-1
) under full load at all times.
Failure to do so can lead to reduced vessel
performance and increased smoke levels,
and can cause permanent damage to your
engine, which is not covered by warranty.
The engine must be installed correctly with
coolant lines, exhaust gas lines and
electrical wiring. Any auxiliary equipment
attached to the engine should be easy to
use and accessible for service. To handle
the drive equipment, propulsion systems
(including the propeller) and other onboard
equipment, always observe the
instructions and cautions given in the
operation manuals supplied by the
shipyard and original equipment
manufacturers.
The GM series engines are designed to be
operated at maximum throttle (3600 min
-1
)
for less than 5% of total engine time (30
minutes out of every 10 hours) and
cruising speed (3400 min
-1
or less).
The laws of some countries may require
hull and engine inspections, depending on
the use, size and cruising area of the boat.
The structural design, vessel application
and installation of this engine all require
specialized knowledge and engineering
skills. See Yanmar’s local subsidiary in
your region or your authorized Yanmar
Marine dealer or distributor.
