What Is This Steering Cable Used For?

The Multiflex SC-16 transfers steering-wheel movement from a compatible mechanical rotary helm to the boat's engine steering mechanism. It is intended for heavy-duty mechanical steering systems on compatible powerboats with engines up to 150HP.

The cable can be used for a new compatible steering installation or as a replacement for an existing SC-16, SSC62 or M66-type cable after the helm connection, engine connection and required length have been confirmed.

The maximum engine rating is determined by the complete steering system, not the cable alone. The helm, cable, engine connection, boat speed and engine installation must all remain within their individual manufacturer ratings.

What Is Included?

The Multiflex SC-16 is supplied as:

• One Easy Connect mechanical steering cable
• Selected cable length
• Stainless steel output ends

Not included:

• Mechanical steering helm
• Dashboard bezel
• Steering wheel
• Engine connection kit
• Other steering-system hardware

Which Steering Helms Are Compatible?

Multiflex uses the SC-16 cable in several of its mechanical steering packages for engines up to 150HP, including systems based on the following helms:

• Multiflex H1 Planetary 150 steering helm
• Multiflex H1N Planetary 150 Non-Reaction steering helm
• Multiflex H3 Reduction 150 steering helm
• Multiflex TH1 tilt steering helm

The Multiflex Easy Connect SC-16 is listed as compatible with the following mechanical steering helms:

Ultraflex steering helms:

• T71FC
• T72FC
• T85
• T81FC

Teleflex steering helms:

• Safe-T
• TQC / NFB

Multiflex steering helms:

• H1 Planetary 150
• H1N Planetary 150 Non-Reaction
• H3 Reduction 150
• TH1 Tilt Planetary

The corresponding packaged systems include the Multiflex MS1, MS1N, MS3 and TMS1 steering systems.

Confirm the exact helm model and cable interface before ordering. Similar-looking mechanical steering cables are not automatically interchangeable.

Is the SC-16 Equivalent to SSC62 or M66?

Multiflex's manufacturer cross-reference associates the SC-16 cable with:

• SeaStar Solutions / Teleflex SSC62
• Ultraflex M66

These references should be used as a selection guide rather than confirmation of automatic compatibility. Check the helm-side connection, engine-side fitting, cable travel, cable routing and required length before installation.

Which Length Options Are Available?

This listing covers SC-16 cables from 8ft to 28ft, increasing in one-foot increments.

The final two digits identify the nominal cable length:

• SC-16-08: 8ft cable
• SC-16-12: 12ft cable
• SC-16-18: 18ft cable
• SC-16-24: 24ft cable
• SC-16-28: 28ft cable

Select the cable according to the replacement measurement rather than the boat's overall length.

How Do You Measure an SC-16 Replacement Steering Cable?

1. Measure the length of the black outer cable jacket marked D in the measuring diagram.
2. Do not include the exposed steering rod, connection nut or metal end fittings.
3. Add 2ft, approximately 610mm, to the measured jacket length.
4. Select the corresponding SC-16 cable length in feet.
5. When the calculated length falls between available sizes, select the next longer whole-foot cable.

Replacement cable formula: Required SC-16 cable length = D + 2ft.

Example: If the outer cable jacket measures 12ft, add 2ft and select a 14ft SC-16-14 steering cable.

The D + 2ft measurement method is intended for replacing an existing cable. A new installation must be measured according to the complete planned cable route through the boat.

Construction and Design

• Heavy-duty mechanical steering-cable construction
• Easy Connect helm-side configuration
• Stainless steel output ends
• Flexible outer cable jacket
• One-foot length increments
• 8in / approximately 203mm minimum bend radius
• Designed for compatible mechanical rotary steering systems
• Exceeds ISO 8848/9775 requirements

Installation and Use

Select the correct cable length before removing the existing steering cable. A cable that is too short can create excessive tension or an inadequate bend radius, while an unnecessarily long cable can result in additional bends and restricted movement.

During installation:

• Maintain a minimum bend radius of 8in / approximately 203mm
• Avoid sharp bends, kinks and crushed cable sections
• Keep the cable away from excessive heat and moving engine components
• Support long cable runs where required
• Check that the cable moves freely through the helm's complete steering range
• Confirm that the engine reaches full steering travel in both directions
• Verify that all helm and engine-side connections are securely retained

Marine steering is a safety-critical system. Installation and servicing should follow the steering-system manufacturer's instructions and be completed by suitably competent personnel.
