Special Boating Situations

The following section covers scenarios that are considered 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.

Shallow Water Operation

You may tilt the drive unit to reduce the draft for shal-
low water running A as long as you do not exceed
1000 RPM. Exceeding 1000 RPM is not necessary. It
will only increase the boat wake and will not increase
boat speed appreciably.
NOTICE! Exceeding 1000 RPM with the drive unit tilt-
ed could damage drive train components.
This type of damage is not covered by war-
ranty. Never attempt to plane the boat or ex-
ceed 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. Never RUN the en-
gine with the drive unit tilted more than 30°
or the drive will be damaged.
When operating in shallow water, be sure the water in-
takes 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.
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.

High Altitude Operation

Volvo Penta EFI engines have programmed altitude
compensation; however, there may be a slight per-
formance loss at altitudes above 5000 feet due to low-
er 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 which is
not covered under the Volvo Penta Limited Warranty.
