2.8 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 motors 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 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 OS 335. 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.
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
switch position. Turning off the power steering at low speeds will reduce the sensitivity of the steering. To
conserve battery power, due to limited engine charging output during extended periods of slow speed
operation, the power steering should be turned off. Refer to the Teleflex® Power Assist manual for further
information.
2.9 Trim Tabs
The trim tabs are recessed into the hull on the transom. 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
