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 steering manufacturer owner’s
manual for specific information on the steering system.
Dual engine inboard boats have two rudders which are offset
from the propeller shaft center line to allow shaft removal
without having to remove the rudders. They are coupled
together at the tiller arms by a tie bar. The rudders are
aligned parallel with 0 toe in to provide maximum stability
on straight ahead runs and proper tracking through corners.
Rudder or steering system damage may require the rudders
to be realigned.
2.6 Trim Tabs
The trim tabs are recessed into the hull on the transom. Dual
rocker switches in the helm are used to control the trim tabs.
The switches are labeled and control bow up and down
movements. They also control 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
provides 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 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.
