Driving

Starting

1 Check the oil level in the engine.
2 Switch on the main switch.
3 Start the engine room fan. Let it run for a few
minutes.
4 Lower the drive if it is tilted.
DPX Double installation: Lower both drives at
the same time.
5 Release the control lever. Idling position.
6 Start the engine. (See "Ignition switch".) Adjust
the speed to idling.
If the engine is equipped with pre-heating, this
must be engaged about 30 s before starting.
WARNING! Do not race the engine immedi-
ately after starting. This could damage the
turbo compressor.
7 Read the instruments. If the readings are abnor-
mal, stop the engine and determine the cause.
8 Check for obstructions in front of and behind the
boat before selecting "Forward" or "Reverse".
The maximum cruising speed is maximum
speed less ca 200 r/min. Good operating econo-
my is achieved if full throttle is avoided.
We recommend that you decrease speed and ra-
ise the drive(s) to Beach range when operating in
shallow water.
DPX double installation: The drives must be
tilted simultaneously to avoid stress on the tie
rod.
Check the instruments regularly while driving.
Stop the engine to determine the cause if any
reading is abnormal.
Power Trim
The DP and DPX drives have a hydraulic trim sys-
tem (Power Trim) which makes it possible to adjust
the boat's trim for maximum comfort and fuel eco-
nomy in different operating conditions.
Every boat has its own unique characteristics that
are also affected by external factors. When you
have got to know your boat thoroughly you can ex-
periment with the best trim angles for different
speed, load and sea conditions. It can generally be
said that when the boat feels well-balanced, easy to
steer and pleasant to operate, then that is the opti-
mal trim angle for the boat. NOTE! For information
about the Power Trim controls and instruments. See
chapters Control units and Tim instruments
