Special Boating Conditions
The following section covers scenarios that are con-
sidered special boating situations. When using the
boat in the following situations, there are some special
procedures to take into consideration in order to keep
the engine, transmission, drive, and propeller in top
working condition.
Operating in Freezing Temperatures
The engine and drive are cooled using raw (sea) water.
Even freshwater (closed cooling) engines use raw
water for cooling purposes. When the air and water
temperatures drop low enough, any water trapped in
your engine or drive will freeze. Freezing water and ice
expand. This expansion could cause parts of the
engine and drive containing water to crack. Always be
sure to drain any trapped water from your engine and
drive if temperatures are expected to drop low enough
to cause freezing.

NOTICE!
When temperatures drop below freezing,
failure to completely drain the cooling system will result
in serious damage to the engine and exhaust mani-
folds.
NOTICE!
Freeze damage to the engine package is not
covered by your Volvo Penta limited warranty.
Upon completion of engine operation, drain the engine
as described below:
● For raw water cooled engines, drain the engine
block and manifold.
● For engines with closed cooling systems, drain
only the manifold.
Shallow Water Operation
You may tilt the drive unit to reduce the draft for shallow
water running
A
as long as you do not exceed 1000
RPM. Exceeding 1000 RPM at high trim/tilt is not nec-
essary. It will only increase the boat wake and will not
increase boat speed appreciably.
NOTICE!
Exceeding 1000 RPM with the drive unit
tilted could damage 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 possible to avoid damage to
drive train.
NOTICE!
Be very careful when operating in shallow
water; the intakes may pick up mud, sand, underwater
vegetation, or other submerged debris. This may lead
to overheating and engine damage.
