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.
2.9 Compass
The compass is on top of the helm. To adjust the compass, read the instructions on “Compass Compensation”
given to you in the literature packet. The compass cannot be adjusted accurately at the factory as it must be
compensated for the influence of the electrical equipment and electronics unique to your boat. Therefore,
the compass should be adjusted by a professional after the electronics and additional electrical
accessories are installed and before operating the boat.
