Power Trim and Tilt Operation

Trimming and tilting the drive is done from a control switch mounted on the remote control or by using the switches
on the dash. When using the dash mounted switches, the bottom button lowers the bow and the top button raises
the bow. The switch on the remote control lever raises and lowers the drive when its upper or lower segment is
pressed.
NOTE! Allow the trim/tilt switch to return to its center position when the drive unit reaches the maximum 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. If the electric motor stops
while tilting, release the switch and allow the overload switch to cool and automatically reset itself. When the
overload switch has reset, tilting may be resumed. Make sure the drive unit is not being restrained, causing the
motor to overheat. If the electric motor still does not operate, check the in-line 5-amp fuse in the remote control
handle, the 10-amp fuse located on the trim/tilt pump, or the 50-amp circuit breaker on the engine.
NOTE! For additional information about Trim and Tilt controls, please refer to the chapter entitled Controls.

Power Trim Operation

The power trim is normally used before you accelerate
onto plane, after you reach the desired RPM or boat
speed, and when there is a change in water or boating
conditions. Locate passengers and equipment in the
boat so that the weight is balanced fore and aft, and
side to side. Trimming will not cancel an unbalanced
load.
To operate the trim, push and hold the switch "bow-
up" or "bow-down" until the desired bow position is
reached. The trim may be operated at any boat speed
or at rest. Avoid operating the trim system when run-
ning in reverse.
Observe the trim/tilt gauge, which indicates the bow
position achieved. The upper scale (0 to 5) of the trim
gauge indicates the "bow-up" positions, and lower
scale (6 to 10) of the trim gauge indicates the "bow-
down" positions.

Determining the Proper Trim

The effect of the maximum "bow-up" and "bow-down"
positions will be similar for most boats. The bow posi-
tion best for your operating conditions could be at any
trim setting between the maximum "bow-up" and
"bow-down" positions.
The boat will be properly trimmed when the trim angle
provides the best boat performance for your operating
conditions. On models without power steering, the
trim position that provides a balanced steering load is
desirable.
To familiarize yourself with the power trim, make test
runs at slower speeds and at various trim positions to
see the effect of trimming. Note the time it takes for the
boat to plane. Watch the tachometer and speedome-
ter readings and the ride action of the boat.
