Ultraflex B47 / B49 Twin-Lever Single Engine Side Mount Control

The Ultraflex B47 and B49 are two-lever, single-action side-mount controls for one compatible outboard engine. One lever controls throttle and the other controls shift. Both can be installed on the port or starboard side and use a nylon-fibreglass body with anodised aluminium levers. Choose the B47 32770A in light grey or the B49 33283S in black.

What Is This Engine Control Used For?

The B47-B49 uses separate single-action levers so throttle and shift are controlled independently. One lever changes engine speed and the second selects forward, neutral or reverse.

It is intended for compatible outboard engine installations. The control does not determine engine horsepower or gearbox capacity; the engine, gearbox, control cable and connection hardware must remain within their manufacturer ratings.

What Is Included?

The selected control is supplied with:

• Selected Ultraflex B47-B49 control in the chosen model and finish

Not included:

• Engine control cables
• Engine-end cable adaptors or clevises
• Optional neutral safety switch
• Connection kits not expressly stated as included
• Installation labour and boat-specific mounting reinforcement

Which Engines and Installations Are Compatible?

This control is intended for compatible outboard engine installations. Before ordering, confirm:

• The number of engines matches the control configuration
• The engine and gearbox use compatible mechanical throttle and shift cables
• The selected cable model is listed as compatible or has the correct Ultraflex connection kit
• The mounting position and handedness match the helm layout
• The panel provides sufficient clearance for the control mechanism and cable bends
• The lever can move through its complete range without contacting the steering wheel, instruments or structure
• The engine-end cable fittings and travel match the engine manufacturer requirements

Compatibility is determined by the complete control, cable, engine and gearbox arrangement rather than by the engine brand alone.

How Does the Control Operate?

• Lever configuration: Two levers
• Control action: Single action: one lever for throttle and one for shift
• Warm-up: Separate throttle and shift levers
• Throttle friction: Friction components provided for throttle adjustment
• Neutral locking: Not stated
• Power trim: Not provided

The warm-up function must only be engaged with the control in neutral. After warm-up, return the lever to the neutral position before re-engaging the shift mechanism.

Which Control Cables Are Compatible?

The following Ultraflex control cables connect without an additional conversion kit:

• C5
• MACH5

The following cables require the stated connection kit:

• C14 and MACH14: K23 connection kit, part number 32773D; sold separately
• C2, C8 and MACHZero: K25 connection kit, part number 32775F; sold separately

Cable compatibility must be confirmed by the exact control model and cable model rather than by the general “33C” description alone. The engine-end adaptor required by the engine manufacturer is separate from the control-box connection kit.

Which Model and Finish Options Are Available?

• B47 / 32770A / 4-B47: Light-grey nylon fibreglass body with anodised aluminium levers
• B49 / 33283S / 4-B49: Black nylon fibreglass body with anodised aluminium levers

The variants share the common control architecture and compatibility stated in this listing. Select by exact model, manufacturer part number, finish and any model-specific function shown in the specification table.

Dimensions and Fitment

• Overall height: 280mm / 11in
• Base dimension: 110mm / 4.3in
• Published width: 230mm / 9in
• Published lever lengths: 130mm / 5.1in and 180mm / 7in

The dimensional drawing must be checked against the physical helm station before the panel is cut. Product photographs are not a mounting template. Allow additional clearance for cable end fittings, smooth cable bends and future servicing.

Optional Safety Switches and Accessories

• K23 connection kit, part number 32773D
• K25 connection kit, part number 32775F

The stated safety compliance is conditional: Install and adjust in accordance with the Ultraflex instructions. An optional switch is not included unless explicitly shown as a supplied component.

Construction and Design

• Nylon fibreglass body with anodised aluminium levers
• Two levers
• Single action: one lever for throttle and one for shift
• Side mount, port or starboard
• Friction components provided for throttle adjustment
• Separate throttle and shift levers
• Not stated
• Not provided
• Fully mechanical operation for the models included in this listing
• Designed for marine throttle and shift control applications

The control mechanism must be mounted to a rigid panel capable of supporting repeated lever loads. Cable routing and adjustment have a direct effect on shift engagement, throttle return and overall operating effort.

Installation and Use

Marine engine controls are safety-critical. Installation and adjustment should be carried out by a competent marine technician using the current Ultraflex instructions and the engine manufacturer’s cable-travel requirements.

Before installation:

• Confirm the exact control model and manufacturer part number
• Confirm the engine count, mounting position and handedness
• Identify the throttle cable and shift cable
• Obtain every required Ultraflex connection kit
• Check the panel cut-out and behind-panel clearance
• Inspect the control cables for corrosion, stiffness, kinks or damaged end fittings
• Place the engine and gearbox controls in their specified neutral and idle positions

After installation and adjustment, check that:

• Forward, neutral and reverse engage positively
• The throttle returns to idle without binding
• The warm-up function operates only as intended
• Any positive neutral lock engages and releases correctly
• Any trim switch operates in the correct direction
• The engine cannot start in gear when the optional safety switch is fitted
• Neither cable is under tension at the ends of lever travel
• The cables do not rub, kink or pass around bends tighter than their permitted radius
• All fasteners, pivots and cable retainers remain secure

The boat must not be used if the control is stiff, does not return to idle, fails to select neutral positively, allows unintended gear engagement or shows abnormal free movement.

Frequently Asked Questions

Does this control include the engine control cables?

No. Throttle and shift cables are supplied separately.

Is the neutral safety switch included?

No. No integrated neutral-start switch stated in the available product data is optional unless a separate package explicitly states otherwise.

Can any 33C-style cable be fitted?

Not automatically. Use the exact Ultraflex cable list and connection-kit requirements shown in this listing.

Can the control be installed without checking the mounting drawing?

No. The panel cut-out, mechanism depth and cable routing must be checked before drilling.

Does each lever control an engine?

No. One lever controls throttle and the other controls shift for one engine.

Is a power trim switch fitted?

No. This model does not include a power trim switch.
