Special boating circumstances
Engine protection mode operation
In a low oil pressure or engine overheat situation, the EFI
system enters an Engine Protection Mode. When this mode
is entered, normal engine operation is limited to 2500 RPM
or less. Above 2500 RPM the engine will exhibit poor run-
ning characteristics. Use the oil pressure and water tempera-
ture gauges to verify a problem exists, then check the en-
gine crankcase for proper oil level and the water inlets for
obstructions. The low oil pressure/engine overheat problem
must be corrected before the engine will return to normal
operation. To leave the Engine Protection Mode after the
problem is corrected, turn engine off then
START again.
NOTE! If the problem continues, contact your nearest Volvo
Penta dealer and have the engine checked.
Shallow water operation
You may tilt the drive unit to reduce the draft for shallow
water running as long as you do not exceed 1000 RPM. Ex-
ceeding 1000 RPM is not necessary. It will only increase the
boat wake and will not increase boat speed appreciably.
Caution!
Exceeding 1000 RPM with the drive unit tilted could dam-
age drive train components. This type of damage is not
covered by warranty. Never attempt to plane the boat or
exceed 1000 RPM with the drive unit in a partially tilted
position. Always return to the trim range as soon as pos-
sible to avoid damage to drive train.
Never run the engine when the drive unit is tilted more
then 30° or the drive will be damaged.
When operating in shallow water, be sure the water intakes
located in the lower gear unit are submerged at all times.
Proceed at slow speed and lower drive unit immediately when
deeper water is reached.
High altitude operation
Volvo Penta EFI engines have programmed altitude com-
pensation; however, there may be a slight performance loss
at altitudes above 5000 feet due to lower air density. If you
are boating above 5000 feet for a short time, a lower pitch
propeller will restore some of the lost performance. Long term
use above altitudes of 5000 ft. may require a change in gear
ratio.
Operating procedure for freezing
temperatures
When freezing temperatures are forecast and the boat will
be operated and left in the water, the drive unit must remain
in the tilted down (submerged) position at all times to pre-
vent water in the drive unit from freezing. Upon completion
of engine operation, drain the engine as described in the
Maintenance section.
Salt water operation
Your can use your Volvo Penta sterndrive in either fresh or
salt water.
We recommend that you use fresh water to flush out the
engine and drive after you use it in polluted or salt water.
This will prolong the service life of the manifolds and risers.
Contact your authorized Volvo Penta dealer for an engine
flushing kit that allows you to flush out the engine whether it
is in or out of the water.
If your boat is moored for long periods of time, tilt the drive
unit out of the water. After you remove your boat from the
water, lower the drive unit to the
RUN (down) position until
the cooling system drains thoroughly.
Rinse the entire drive exterior with fresh water, then dry it
and spray it with anticorrosion spray.
Twin engine operation
Twin engine boats may have only one engine with a fully
operational power steering system. That power steering sys-
tem is on the starboard engine; therefore, when operating
on a single engine use the starboard engine.
NOTE! Using a port engine that does not have a functional
power steering system will cause an increased ef-
fort in steering control, due to absence of power
assist.
Some twin engine boats may have both engine power steer-
ing systems coupled together with a priority valve. This al-
lows the use of either engine to provide power assist steer-
ing.
Manuver a twin engine boat in the same manner as a single
engine boat. When leaving or approching the dock, or for
any close manuvering at idle speed, differential thrust my be
applied for extra manuvering capabilities. If manuvering in a
small area and a turn to port or starboard is requred, place
the control on the inside of the turn in reverse momentarily
to help tighten the turn. Whenever manuvering in small ar-
eas keep the engines at idle.
Warning!
If maneuvering with an engine that has the power steer-
ing pump which stops, the power steering assist is lost.
Failure to follow the above maneuvering procedure could
result in a collision and personal injury.
Both engines must be running during close maneuver-
ing or at slow speeds. If only one engine is running, water
may be forced back through the underwater exhaust
outlet and cause serious engine damage.
Do not attempt to plane the boat while operating on a
single engine. The propellers are selected for the boat
to operate optimally with twin engines. Operating with a
single engine could cause engine damage.
