Multiflex EC-020 Throttle & Fuel Shut Off Engine-Stop Engine Control Cable

The Multiflex EC-020 Throttle & Fuel Shut-Off Cable is a standard mechanical push-pull cable for compatible throttle, engine-stop and fuel shut-off linkages. It provides 75mm travel through a 7mm conduit and uses a lubricated 1.9mm stainless-steel solid-wire inner.

Multiflex cross-references the EC-020 to SeaStar CC343 and Ultraflex B14. Historical Multiflex catalogue data also associate the cable with the LM-K-3 cable clamp and LM-K-12 pivot, but current retail package contents must be confirmed.

What Is the Multiflex EC-020 Used For?

The EC-020 transfers mechanical push-pull movement between a compatible remote control and the connected engine or gearbox linkage. The cable does not create movement itself; it transmits the movement generated by the control lever.

It can form part of a correctly specified:

• Diesel or petrol engine fuel shut-off linkage
• Mechanical engine-stop control
• Compatible throttle lever
• Replacement CC343 or B14 cable installation
• Industrial or marine push-pull linkage where the ends and load are correct

What Is Included?

Historical catalogue data identify LM-K-3 and LM-K-12 fittings, but the current product page does not provide a retail packaging list. Confirm whether the K3 clamp, K12 pivot or any loose hardware is supplied with the selected length.

• 1 x Multiflex EC-020-XX cable in the selected length

What Is Not Included?

Not included unless expressly stated:

• Remote control lever or control box
• A second throttle or shift cable
• Engine throttle lever or gearbox selector lever
• Cable outer-casing clamp or structural support bracket
• Cable-end eye, clevis, pivot or ball joint unless shown as part of the cable
• Engine-specific adapter, retaining clip, pin, nut or washer
• Electrical start-in-gear or neutral-safety components
• Steering helm, steering wheel or steering cable

Which Engines and Control Systems Are Compatible?

Multiflex publishes the EC-020 for Mechanical throttle, engine-stop and fuel shut-off linkages. The cable should be selected by its complete end-fitting pattern and required travel, not from engine brand alone.

Before ordering, confirm:

• Mechanical fuel shut-off levers
• Mechanical engine-stop controls
• Compatible throttle linkages requiring 75mm travel
• Systems using the CC343 / B14 cable-end family
• The complete cable family marked on the removed cable
• Both control-head and engine-side end fittings
• Required cable travel and lever movement
• Push-to-open or pull-to-open operation
• Cable routing length and available bend radius
• Any engine-specific clip, adapter or retaining hardware

Which Control Function Does This Cable Operate?

The EC-020 is published for Throttle or fuel shut-off / engine stop. It should not be used for a different control function unless the complete end fittings, travel and load requirements are approved for that application.

How Many Cables Are Required?

This listing supplies one cable. The required quantity depends on the control system.

• One cable for one mechanical control circuit
• Two cables for a typical single-engine throttle-and-shift installation
• Four cables for a typical twin-engine throttle-and-shift installation
• Additional cables where a correctly engineered dual-station or specialist control system requires them

What Does the XX Suffix Mean?

In the part number EC-020-XX, XX identifies the nominal cable length in feet. For example, EC-020-12 identifies a nominal 12ft cable.

The suffix does not identify the cable travel, engine application or end-fitting family. Those are determined by the model code before the suffix.

How Is the Correct Cable Length Selected?

For a new engine-control installation, Multiflex instructs users to measure the routed distance from the control head to the throttle or clutch/shift connection, round the total up to the next whole foot and, for an outboard installation, add approximately 3ft to allow for engine movement.

For replacement work, the most reliable starting point is the model and length printed on the existing cable. Compare both end fittings before ordering because two cables of the same length can use different engine-specific terminals.

• Measure the intended routed path rather than a straight-line hull dimension
• Allow for gradual curves and service access
• Avoid unnecessary loops
• For outboards, check cable movement through full steering and tilt travel
• Round up to the next available whole-foot length rather than selecting a cable that is too short

What Does Cable Travel Mean?

The published travel for the EC-020 is 75mm. Travel is the usable linear movement of the cable inner between its two operating limits.

The selected cable must provide enough movement for the remote control and engine linkage without bottoming out, overtravelling or leaving incomplete gear engagement or throttle movement. A matching cable length does not compensate for incorrect travel.

What Is the Minimum Bend Radius?

The published minimum bend radius is 8in / approximately 200mm. The cable must not be routed around a tighter curve.

Larger, gentler bends and fewer changes of direction reduce friction and improve service life. The minimum figure is a limit, not a target routing radius.

Do the Published Cross-References Guarantee Direct Fitment?

No. Multiflex cross-references the EC-020 to CC343 and B14, but its cross-reference chart states that the information is for reference and users must confirm interchangeability before installation.

Direct replacement depends on both end fittings, usable travel, length, conduit routing, retaining hardware and the control or engine generation.

What Are the Cable Dimensions?

Multiflex publishes the conduit dimension as 7.0mm and the inner construction as 1.9mm lubricated stainless-steel solid wire. Overall length varies with the selected XX suffix.

Unless separately stated by Multiflex, the following dimensions are not published:

• Overall end-to-end length tolerance
• Control-end terminal dimensions
• Engine-end terminal dimensions
• Bulkhead or clamp-hub thread dimensions
• Exposed rod length
• Terminal-eye or clevis dimensions
• Cable weight by length
• Maximum push and pull working load

Does the Cable Include the End Fittings and Mounting Hardware?

The cable is supplied as a complete cable assembly with its model-specific fixed end components. Multiflex does not provide a universal loose-parts list for every retail length and market.

Do not assume that separate pins, clips, cable clamps, ball joints, clevises, terminal eyes, engine brackets or control-box adapters are included unless the seller expressly identifies them.

Can This Cable Be Used as a Steering Cable?

No. The EC-020 is an engine control cable. It is not a rotary steering cable, rack-and-pinion steering cable, hydraulic hose or steering link arm.

Engine control cables and steering cables use different load cases, end fittings, retaining methods and safety requirements.

Is a Maximum Working Load Published?

No numerical maximum push load, pull load or fatigue rating is published on the current product page. The complete control system must be selected according to the engine or gearbox operating force, control-lever geometry, cable route, cable length and the rating of the lowest-rated component.

Which Multiflex Accessories Are Associated With the EC-020?

Historical Multiflex catalogue data associate the EC-020 with the LM-K-3 cable clamp and LM-K-12 stainless-steel pivot. Current sellers may supply the cable alone or as a kit, so the product contents must be checked before ordering.

• K3: Cable outer-casing clamp
• K12: Stainless-steel pivot for the moving cable end
• The clamp and pivot perform different functions and neither should be assumed to be included without confirmation

Is the EC-020 a Gear-Shift Cable?

The EC-020 is published for throttle or fuel shut-off duty rather than a standard forward-neutral-reverse shift circuit. Do not substitute it for a 3300, Mercury, OMC or Mariner shift cable unless the complete end fittings, travel and control requirements are expressly approved.

Installation and Safety

Engine throttle, shift and shut-off controls are safety-critical. Installation and adjustment should be completed by a competent marine technician using the current Multiflex, remote-control, engine and gearbox instructions.

• Confirm that the cable family is EC-020
• Read the model and length from the removed cable where possible
• Compare both cable ends before ordering
• Confirm the remote-control and engine/gearbox generation
• Verify the required cable travel
• Confirm push-to-open or pull-to-open operation
• Measure the routed cable length accurately
• Allow additional length for outboard movement where required
• Maintain at least the published minimum bend radius of 8in / approximately 200mm
• Use the fewest and largest-radius bends practical
• Keep the cable clear of exhaust components, sharp edges and moving machinery
• Support the cable outer without crushing or kinking the conduit
• Do not clamp the moving rod
• Install the correct terminal pin, clip, nut or adapter
• Set the throttle and control to idle before final throttle adjustment
• Set the control and gearbox to neutral before final shift adjustment
• Confirm full forward, neutral and reverse engagement where used for shifting
• Confirm complete idle-to-full-throttle movement where used for throttle
• Ensure the cable does not bottom out before the engine or gearbox reaches its stop
• Check that no surrounding structure loads the cable ends sideways
• Recheck all retainers and clamps after the initial operating test
• Replace a cable that is stiff, corroded, abraded, kinked or has reduced usable travel
• Do not shorten, weld, straighten, dismantle or internally lubricate the cable unless Multiflex publishes an approved procedure
• Do not operate the vessel if gear selection, throttle return or engine-stop operation is uncertain

Maintenance

Inspect the complete cable route, end fittings and retaining hardware periodically. A gradual increase in operating effort, lost travel, damaged conduit or corrosion indicates that the cable or related linkage requires attention.

• Keep the cable ends and external linkage clean
• Inspect terminal pins, clips and nuts for wear or looseness
• Check the outer jacket for abrasion, cracking, heat damage or crushing
• Confirm the control returns correctly to idle and neutral
• Replace the complete cable rather than attempting an internal repair
• Recheck the cable after any engine, gearbox or control-head service
