Always use oil of the correct grade for your system. If the oil is too viscous (thick), it can make the system stiff and heavy.

A typical cable steering system consists of: Steering Helm CABLE STEERING SYSTEM

The steering helm is a gearbox arrangement mounted on the dashboard of the boat. All have a 3/4” standard tapered shaft. Wheel is mounted on the shaft of the helm to operate the mechanical gearing and cable. Steering Cable The steering cable is a push / pull mechanical cable which converts the rotary motion of the helm to linear motion at the engine / rudder. One end of the cable is connected to the helm and the other end to the rudder. Bezel Kit The bezel kit is a plastic part with related hardware which is mounted between the steering wheel and dashboard to cover the helm hardware. Connection Kit Connection kits are used to connect the steering cable to the engine / rudder.

In order to ensure proper functionality of the mechanical steering system and safety of the boat, the selection of the correct steering system becomes a critical exercise. Due to various combinations of engine and boat configurations, the following need to be considered while selecting the steering system. • Boat speed • Engine power • Engine type • Displacement HOW TO SELECT THE CORRECT STEERING SYSTEM

HOW TO MEASURE FOR NEW STEERING CABLE

C

A

B

• Boat size • Hull type

Higher engine power or boat speed increases the load on the steering system due to higher torque generated by the propeller. Bigger boats with inboard engines and higher displacement hulls have higher rudder loads and may require hydraulic steering systems.

1. Add A + B + C 2. Subtract 10cm for each 90° bend in the cable 3. For installation through the engine tilt tube, add 30.5cm to the measurement calculated above.

Selection guide for Multiflex mechanical steering systems:

Steering cable

A (50) + B (250) + C (80) = 380 - 20 for two 90° bends = 360 + 30.5 for a through-tube installation = 390.5cm = order 4.00 metre length. Transom support or splashwell mounting - Fig 2, 3 Example (dimensions in cm): A (50) + B (250) +C (80) = 380 -20 for two 90° bends = 360 = order 3.75 metre length.
