and is normal. Refer to the steering manufacturer owner’s manual for specific information on the steering
system.
Dual engine outboards are coupled at the tiller arms by a tie bar. The engines must be aligned with each other
to provide maximum stability on straight ahead runs and proper tracking through corners. Engine or steering
system damage may require the engines to be realigned.
SOME AUTOPILOTS HAVE ENGINE POSITION SENSORS THAT ARE MOUNTED TO THE
HYDRAULIC STEERING CYLINDER. WITH THESE AUTOPILOTS, THE ENGINE POSI-
TION SENSOR BRACKET COULD HIT THE TRANSOM WHEN THE ENGINES ARE TILTED
TO THE FULL UP POSITION AND CAUSE DAMAGE TO THE ENGINE RIGGING, THE
AUTOPILOT OR THE TRANSOM. IF YOU HAVE AN AUTOPILOT INSTALLED ON YOUR
BOAT, YOU SHOULD MONITOR THE LOCATION OF THE ENGINE CABLES AND AUTO-
PILOT BRACKETS AS THE ENGINES ARE TILTED TO DETERMINE THE BEST ENGINE
POSITION AND MAXIMUM ENGINE TILT FOR YOUR APPLICATION.
TILT HELM
A tilt helm may be installed on the 2870 Offshore. To tilt the wheel, depress the lever located in the base of
the helm. Make sure it locks into position.
DO NOT ATTEMPT TO ADJUST THE HELM WHEEL POSITION WHILE UNDERWAY.
2.9 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
