Special Attention

On the X10, XT23, X46, and XSTAR models, attitude adjustment
plates are limited to seventy-five percent (75%) maximum exten-
sion when the boat speed exceeds twenty miles per hour (20 mph)
or thirty-two kilometers per hour (32 km/h).

On the X20 model, attitude adjustment plates are limited to sev-
enty-five percent (75%) maximum extension when the boat speed
exceeds twenty five miles per hour (25 mph) or forty kilometers per
hour (40 km/h).

On the X23 model, attitude adjustment plates are limited to eighty-
five percent (85%) maximum extension when the boat speed
exceeds twenty five miles per hour (25 mph) or forty kilometers per
hour (40 km/h). Maneuvering a boat with the attitude adjustment
plate extended requires practice to master. Initial times running
with the attitude adjustment plate extended should be done at
low speed with plenty of room. This is critical to learning how the
attitude adjustment plate affects control and maneuverability, es-
pecially when teaming the attitude adjustment plate with surf tabs.

Additional Special Attention

DO NOT use the attitude adjustment plate(s) to board the boat. The
edges are sharp and can easily slice through skin. The plate(s) is also
not sturdy enough to withstand many people’s body weight. Damage
to the plate(s) in this manner is not covered under warranty. Use only
boarding ladders and swim platforms to board from the transom side
when boats are equipped with an attitude adjustment plate(s).

Because our models have different weights, lengths, speed
and performance, it will take some practice for the operator to
understand how the boat reacts with the attitude adjustment plate
installed. The plate will allow your boat to get on plane faster and
continue planing at lower speeds. This will improve visibility and
the overall safety of your boat. When making adjustments with the
attitude adjustment plate, use short momentary taps of the switch.
Continued practice will help you become familiar with how the
plates perform.

Special Attention

Because these plates can adversely affect boat handling if not
utilized properly, the following information is provided to assist
operators in determining the correct usage of the attitude
adjustment plate(s).

Special Conditions

Head Sea:

Lower the plate by tapping slightly on BOW DOWN on a

single system. This will bring the bow down while maintaining speed.
This also allows the hull of the boat to absorb the impact of the
waves. This adjustment will result in a more efficient and smoother
ride. Changes should be made in small increments to ensure
maintaining control of the boat.

Following Sea:

Make sure the plates are fully retracted by pressing

BOW UP on both sides of a dual system, and BOW UP on a single
system. This will bring the plate(s) up to a fully retracted position,

Never use the attitude adjustment plate(s) to board or assist
in boarding the boat. Sharp edges can cut individuals, causing
potentially serious bleeding. Damage to the plate(s) from people
using it to board the boat is not covered under warranty.

Additional Special Attention

Care should also be taken when backing up the boat in shallow
water, removing boats from the water on steeply pitched access
areas, or backing up with the boat on a trailer. The attitude
adjustment plate(s) does not fold or retract, and it may require
additional clearance to avoid damage to the plate(s). Resulting
damage from failure to follow instructions is not covered under
warranty.

Care must be taken to ensure that there is always sufficient
clearance around the attitude adjustment plate, whether it
is in the water or out, particularly on a trailer. The attitude
adjustment plate(s) extends beyond the boat transom and is
not foldable or retractable. Damage to the plate(s) from failure
to allow sufficient clearance is not covered under warranty.

decreasing lift in the stern and allowing the bow to rise. If the
plate(s) is/are deployed, the bow may dig.

Shallow Water/Hole Shot:

Lower the plate completely by pressing

BOW DOWN. This provides lift in the stern of the boat and will keep
the bow down. As you throttle up and speed increases, raise the tab
by pressing UP.

Porpoising:

To stop porpoising, press BOW DOWN on the attitude

adjustment plate control. The plate(s) needs only to be deployed
slightly to correct this adverse situation.

Improper use of attitude adjustment may result in loss of control,
which could result in serious injury or death.

• While at higher speeds, do not over-trim, as this will cause the

bow to lower quickly, resulting in a reduction of speed and may
cause the boat to veer.

• When in following seas or when running an inlet, the plates should

be fully retracted. This will allow for optimal performance.

• Electromechanical actuators provide an instant response. When

making adjustments, use short momentary taps of the switch.
