DO NOT ATTEMPT TO ADJUST THE HELM WHEEL POSITION WHILE UNDERWAY.

2.8 Trim Tabs

The trim tabs are recessed into the hull under the transom area. Switches are used to control the trim tabs.

The switches are labeled and control bow up and down movements. It also controls starboard and port up and

down movements. Bow up and bow down will control the hull planing attitude, while port and starboard up

and down provide control for the hull trim side to side.

Before leaving the dock, make sure that the tabs are in the full “UP” position by holding the control in the

bow "UP" position for ten (10) seconds.

Always establish the intended heading and cruise speed before attempting to adjust the hull attitude with the

trim tabs. After stabilizing speed and direction, move the trim tabs to achieve a level side to side running

attitude being careful not to over trim.

After depressing a trim tab switch, always wait a few seconds for the change in the trim plane to take effect.

Avoid depressing the switch while awaiting the trim plane reaction. By the time the effect is noticeable

the trim tab plane will have moved too far and thus the boat will be in an overcompensated position.

When running at a speed that will result in the boat falling off plane, lowering the tabs slightly, bow down,

will improve the running angle and operating efficiency. Too much bow down tabs can reduce operating

efficiency and cause substantial steering and handling difficulties.

Be extremely careful when operating in a following sea. The effect of trim tabs is amplified under such

conditions. Steering and handling difficulties can result from improper trim tab usage, particularly in a

following sea. Always raise the tabs to the full bow "UP" position in these conditions.

When running at high speeds be sure that the tabs are in the full “UP” position. Only enough trim plane

action should be used to compensate for any listing. Trim tabs are extremely sensitive at high speeds. Adjust

for this and be prepared to slow down if difficulties arise.

When running into a chop, a slight bow down attitude will improve the ride. Be careful not to over trim.

Handling difficulties may result.

TRIM TAB INDICATOR

While the switches are labeled to indicate the reaction of the bow of the boat, the

L.E.D. displays indicate the position of the trim tabs. As an example, when adjusting

the starboard bow up or down, the L.E.D. indicator on the right side of the panel will

be activated indicating the movement of the port tab. Refer to the trim tab operation

manual.

POWER STEERING (Optional)

The power steering system uses an electrically controlled hydraulic pump to provide power to the standard

hydraulic steering system. Additional components are a helm mounted power steering switch and a hydraulic

pump. The switch activates the power steering feature. Manual steering is always available regardless of the
