OS 335

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
