Multiflex Sigma W10B Compact Steering Wheel - 280mm

The Multiflex Sigma W10B, also catalogued as LM-W-10B, is a compact black 280mm / 11in three-spoke marine steering wheel for compatible marine helms with a standard 19mm / 3/4in tapered shaft. It is manufactured from high-strength engineered plastic and has an inbuilt mounting hub, so a separate steering-wheel hub is not required.

What Is This Steering Wheel Used For?

The Multiflex Sigma W10B provides manual steering input when fitted to a compatible marine steering helm. It is suitable for new installations or as a replacement for an existing steering wheel with the same standard 19mm / 3/4in tapered hub fitting.

Its compact 280mm diameter requires less helm-station clearance than a larger 350mm steering wheel, making it suitable for dashboards where wheel space is restricted.

The steering wheel does not determine the engine-power capacity of the steering system. The helm, mechanical steering cable or hydraulic components must remain within their individual manufacturer ratings.

What Is Included?

The Multiflex Sigma W10B is supplied with:

• Black three-spoke marine steering wheel
• Inbuilt standard 3/4in tapered hub

Not included:

• Mechanical or hydraulic steering helm
• Mechanical steering cable
• Hydraulic steering components

Which Steering Helms Are Compatible?

The Multiflex Sigma W10B is designed for compatible marine steering helms with a standard 19mm / 3/4in tapered steering-wheel shaft.

Before ordering, confirm:

• The helm has a standard 3/4in tapered shaft
• The shaft is tapered rather than straight or splined
• The dashboard provides clearance for the 280mm wheel diameter
• The existing helm shaft, key and retaining hardware are serviceable
• The wheel can turn through the complete steering range without contacting nearby controls or instruments

Compatibility is determined by the helm-shaft dimensions and taper rather than the steering-system brand alone.

What Colour Is Supplied?

This listing is for the black Multiflex Sigma W10B steering wheel.

The W10B model is supplied in black. No alternative colour is included in this listing.

Dimensions and Fitment

• Overall diameter: 280mm / approximately 11in
• Hub taper: 19mm / 3/4in
• Number of spokes: Three
• Hub type: Inbuilt
• Colour: Black

Construction and Design

• High-strength engineered-plastic construction
• Compact 280mm diameter
• Three-spoke wheel structure
• Inbuilt mounting hub
• Black finish
• Non-metallic wheel structure
• Designed for standard marine helm installations

The inbuilt hub allows the wheel to mount directly onto a compatible tapered helm shaft without requiring a separate steering-wheel hub.

Installation and Use

Confirm that the steering helm has a standard 19mm / 3/4in tapered shaft before installation. The wheel must seat correctly on the taper without movement between the hub and shaft.

Secure the wheel using the shaft key and retaining hardware specified by the helm manufacturer. After installation, turn the wheel through the steering system's complete range and check that:

• The wheel does not contact the dashboard, instruments or controls
• The helm operates smoothly through its full travel
• The wheel remains securely seated on the tapered shaft
• There is no abnormal movement between the hub and helm shaft

Marine steering is a safety-critical system. Worn shaft keys, retaining nuts, helm shafts or other steering components must be replaced before the boat is used.
