2665 DENALI 30
EXCESSIVE TRIM FOR THE OPERATING CONDITIONS, EITHER TRIM UP OR
DOWN, CAN CAUSE BOAT INSTABILITY, PROPELLER CAVITATION, OR MAKE
STEERING THE BOAT MORE DIFFICULT. IF THE BOAT BEGINS TO FEEL UN-
STABLE OR IS HARD TO STEER, SLOW DOWN AND ADJUST THE TRIM ANGLE.
2.7 Steering System
The steering system is hydraulic and made of two main components: the helm assembly and the
hydraulic cylinder. The helm unit acts as both a fluid reservoir and pump. Turning of the helm,
or steering wheel, pumps the fluid in the hydraulic hoses and activates the hydraulic cylinder
causing the outdrive to turn. A slight clicking sound may be heard as the wheel is turned. This
sound is the opening and closing of valves in the helm unit and is normal. Refer to the
manufacturer owner’s manual for specific information on the steering system.
2.8 Trim Tabs
The 2665 Denali uses rocker switches to control the trim
tabs. The switch is labeled and controls 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 listing.
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 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 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.
