Operation
Shifting between forward and reverse should be done at
idling. Shifting at higher engine speeds can be uncomfor-
table for passengers and cause unnecessary stress on
the stern drive/reverse gear, or cause the engine to stop.
If you attempt to shift gear at an excessive engine speed,
a safety function cuts in automatically, and delays shifting
until engine speed has fallen to 1500 rpm.
Always do a forwards/revers operation as follows:
1. Reduce engine speed to idle and let the boat more or
less lose way.
WARNING! Never shift to reverse when the boat
is planing.
2. Move the control lever to neutral with a rapid, distinct
movement. Make a brief pause.
NOTE! A beep will sound to indicate that the control
lever is in neutral.
3. Then move the control lever to reverse with a rapid,
distinct movement and increase engine speed.
IMPORTANT! If the boat has twin engines, it is
important that both should be running during re-
verse maneuvers, to avoid the risk of water entry
(via the exhaust pipe) into the stationary engine.

Power Trim

Your Volvo Penta drive is equipped with a hydraulic trim
system, with which you can change the angle of the drive
in relation to the transom. This will affect the running po-
sition of the boat and make it possible to optimize boat
handling in various conditions.
Power trim is operated from the control position using the
panels, controls and instruments.
NOTE! The engine can not be started with the drive in
the "Tilt range".
WARNING! Avoid over-trimming the drive system
as this can adversely effect the steering of the boat
severely.
IMPORTANT! Avoid running with the drive fully
trimmed for long periods (when planing). Apart from
excessive fuel consumption this can cause cavity
damage to the propeller(s).
