Trim/tilt motor protection
IMPORTANT! Always allow the trim/tilt switch to return to
its center position when the drive unit reaches the maxi-
mum raised or lowered position. This will prevent your
trim/tilt motor from overheating.
The trim/tilt motor is protected from overheating by an internal
thermal overload switch. Should the electric motor stop while
tilting, release the switch and allow the overload switch to cool
and automatically reset itself. When the overload switch has re-
set, tilting may be resumed. Make sure the drive unit is not be-
ing restrained, causing the motor to overheat. If the trim motor
still does not function, check the circuit breaker on the pump/
pump bracket (10 A), the inline fuse (5A) in the Power Trim
switch cabling (if mounted). Also check the circuit breaker on
the fuse box (50 A). Please refer to Electric system for more
information.

Impact protection

The trim/tilt system provides impact protection for the drive unit.
Still, impact damage can occur in either forward or reverse
directions. Care must be taken:
l
When operating in forward or reverse
l
When backing at low speed
l When trailering boat
l When launching boat
Impact damage is more likely to occur when in a turn where
side loads are placed on the drive unit.
If the drive unit strikes a solid object, throttle back and shut off
engine immediately. Closely inspect the boat and drive unit for
damage, particularly the transom shield assembly that contains
steering system components. Check engine compartment for
water leakage.
If there is obvious or suspected damage, operate boat at low
RPM and take your boat to a Volvo Penta dealer for inspection.
Have necessary repairs made immediately. Operating a
damaged drive unit could cause additional damage and could
become very costly to repair.
IMPORTANT! Failure to inspect for damage may:
l
Result in sudden loss of steering control.
l
Adversely affect your boat and drive unit's ability to
resist subsequent high speed impacts.
NOTE! When moving in reverse there is no impact protection.
Use caution when moving in reverse. Do not exceed 2500
RPM.
