Ultraflex K23 C14 & Mach14 Control Cable Connection Kit For B47 & B49 Control Boxes

The Ultraflex K23 32773D is a mechanical control-cable connection kit for fitting Ultraflex C14, MACH14 and compatible BRP / OMC-type "OS" cables to Ultraflex B47 and B49 twin-lever side-mount control boxes. The kit installs at the control-box end of the cables and provides the model-specific interface required between the cable terminals and the internal control mechanism.

What Is This Connection Kit Used For?

The Ultraflex K23 allows compatible C14, MACH14 and BRP / OMC "OS" control cables to be installed in an Ultraflex B47 or B49 control box.

The B47 and B49 are twin-lever controls in which:

• One lever operates the engine throttle
• One lever operates the gearbox or shift mechanism
• Each lever performs one control function
• The control can be installed on a compatible port- or starboard-side mounting surface

The cable-end geometry used by C14 and MACH14 cables does not connect directly to the standard B47/B49 mechanism. The K23 supplies the required model-specific connection components.

The K23 does not alter the cable stroke, engine compatibility or operating limits of the control system. The control box, cables and engine-side connections must still be suitable for the engine installation.

What Is Included?

The Ultraflex K23 is supplied as:

• One Ultraflex K23 multi-piece connection kit
• Control-box connection components for compatible C14, MACH14 or BRP / OMC "OS" cables
• Components required to interface the specified cables with a B47 or B49 control mechanism

Not included:

• Ultraflex B47 or B49 control box
• C14 or MACH14 control cables
• BRP / OMC engine control cables
• Engine-side cable connection components
• Engine-specific throttle or shift fittings
• Neutral-safety switch
• Control-box mounting hardware not supplied with the control
• Installation tools

This listing covers the K23 connection kit only.

Which Control Boxes Are Compatible?

• Ultraflex B47 / 32770A: Light-grey twin-lever side-mount control
• Ultraflex B49 / 33283S: Black twin-lever side-mount control

Both controls are:

• Twin lever
• Single action
• Side mounted
• Mechanically operated
• Intended for compatible outboard-engine installations

The K23 should not be selected for another Ultraflex control solely because that control also has two levers. The internal cable mounting arrangements differ between control models.

Which Control Cables Are Compatible?

The K23 is specified for:

• Ultraflex C14 control cables
• Ultraflex MACH14 control cables
• Compatible BRP / OMC-type "OS" control cables

Before ordering, check the cable model printed on the existing cable jacket or terminal.

The K23 is not a universal adaptor for all marine engine control cables.

What Is the Difference Between K23 and K25?

The correct kit is determined by the control-cable family.

• K23 / 32773D: For C14, MACH14 and compatible BRP / OMC "OS" cables
• K25 / 32775F: For C2, C8 and MACHZero cables

Ultraflex also states that:

• C5 cables: Connect to B47 and B49 controls without a separate adaptor kit
• MACH5 cables: Connect to B47 and B49 controls without a separate adaptor kit

Do not use the K23 with C2, C8 or MACHZero cables. These cable types use a different terminal arrangement and require the K25.

Does the K23 Determine Engine Compatibility?

No. The K23 only provides the connection between the compatible control cable and the B47 or B49 control box.

Complete compatibility still depends on:

• Engine manufacturer
• Engine model and year
• Required throttle cable type
• Required shift cable type
• Cable stroke
• Cable length
• Engine-side connection fittings
• Push or pull operating direction
• Control-box installation and adjustment

Confirm both the control-box end and engine end of each cable before ordering a complete control system.

Installation and Adjustment

Mechanical engine controls are safety-critical. Installation should be completed by a competent marine technician familiar with throttle and shift control systems.

Before installation:

• Confirm that the control box is a B47 or B49
• Confirm that the cables are C14, MACH14 or compatible BRP / OMC "OS" cables
• Check that the cables are the correct length
• Inspect the cable terminals and outer casings
• Check the control mechanism for wear or corrosion
• Place the control and engine linkage in neutral
• Isolate the engine starting circuit

During installation:

• Follow the current Ultraflex B47/B49 installation instructions
• Fit the K23 components in the stated orientation
• Do not drill, grind, bend or modify the adaptor components
• Ensure all cable terminals are fully retained
• Route the cables with smooth bends
• Avoid sharp edges, heat and moving engine components
• Do not clamp the cables in a way that deforms the outer casing
• Adjust the shift and throttle travel independently

After installation, check with the engine switched off that:

• The control levers move smoothly
• Neutral is correctly aligned
• Forward and reverse engage without excessive force
• The shift linkage is not forced against its mechanical stops
• The throttle reaches idle correctly
• Full throttle can be selected without over-travelling the engine linkage
• The cables do not bind at any control position
• All retaining components remain secure
• Any specified neutral-start protection operates correctly

Do not operate the boat if the control is stiff, the shift position is uncertain or any connection component is loose.

Frequently Asked Questions

Does the K23 include the B47 or B49 control box?

No. The K23 is the connection kit only. The control box is sold separately.

Are C14 or MACH14 cables included?

No. The required throttle and shift cables must be ordered separately in the correct lengths.

Can the K23 be used with a C2 or C8 cable?

No. C2, C8 and MACHZero cables require the Ultraflex K25 connection kit.

Do C5 and MACH5 cables require the K23?

No. Ultraflex states that C5 and MACH5 cables connect to the B47 and B49 controls without an adaptor kit.

Does the K23 fit both B47 and B49 controls?

Yes. The same K23 kit is specified for both control-box models.

Can it be used with BRP or OMC cables?

It is listed for compatible BRP / OMC-type "OS" cables. Confirm the exact cable terminal before ordering.

Is this an engine-side connection kit?

No. The K23 installs at the control-box end. Engine-side cable fittings are separate and depend on the engine application.
