PRODUCT OVERVIEW
YANMAR 6LPA FEATURES
AND APPLICATIONS
The 6LPA series are 6-cylinder, 4-stroke
direct injection diesel engines equipped with
liquid coolant systems.
The 6LPA-STP2 engines are equipped with
a marine gear (ZF63A1 or KMH50A).
The 6LPA-STZP2 engines are equipped
with a stern drive (Mercruiser Bravo).
These engines are designed for pleasure
craft use.
It is recommended that new vessels be
propped so the engines can operate at
50 - 100 rpm above the rated power output
(3800 rpm) to allow for future added weight
and hull resistance. The engine must be
able to reach the rated power output rpm
under full load at all times.
Failure to do so can lead to reduced vessel
performance, lead to increased smoke
levels and cause permanent damage to your
engine.
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 equipment
manufacturers.
The 6LPA series engines are designed to be
operated at maximum throttle (3800 rpm) for
less than 5% of total engine time (30 minutes
out of every 10 hours) and cruising speed
(2800 - 3600 rpm or less) for less than 90%
of total engine time (9 hours out of every 10
hours).
The laws of some countries may require hull
and engine inspections, depending on the
use, size and cruising area of the boat. The
installation, fitting and surveying 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.
