Teleflex Cable steering

 

Mechanical cable steering consists of a rotary helm assembly with a 90

degree or 20 degree bezel kit. This helm connects to a single, Push - Pull

cable. The other end of the cable attaches to the Rudder or Outboard and

is anchored using a connection kit to suit the relevant application.

No Feed Back

NFB helms have a clutch system that locks the steering when you are not

turning the wheel and automatically releases the clutch when you turn the

wheel again. Thus eliminating feedback.

Cable Length

To calculate cable length required. Measure:

A  from the centre of the steering wheel to the gunwale

B  from the dashboard to the transom

C  from the gunwale to the mounting point of rudder / outboard

For rudders (and outboards without Thru tube):

Cable length is A + B + C {Less 10cm (4 inches) for each 90 degree bend}

For outboards WITH Thru tube:

Cable length is A + B + C + 30cm {Less 10cm (4 inches) for each 90 degree bend}

USE THE NEXT SIZE ABOVE THE CALCULATED LENGTH.

Cables are currently converting from metric to imperial.

Therefore depending on availability cables are supplied to the nearest 0.25m or foot.

To identify an existing cable:

Most cables are marked with part number and length on the cable jacket

towards one end of the cable. The measurement of a cable is taken from

the point the cable attaches to the helm to the end of the cable in the

mid stroke position. (as example below)
