What Is This Steering Wheel Used For?

The Ultraflex V23 provides manual steering input when fitted to a compatible marine steering helm. It is suitable for a new steering installation or as a replacement for an existing steering wheel with the same standard 19mm / 3/4in tapered fitting.

Its 400mm / 15.7in diameter requires sufficient clearance around the dashboard, controls and instruments. The wheel must be able to turn through the steering system's complete operating range without obstruction.

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 Ultraflex V23 steering wheel is supplied with:

• Ultraflex V23 32397D five-spoke steering wheel
• Mounting hub for a standard 3/4in tapered shaft
• Wood centre cap

Not included:

• Mechanical or hydraulic steering helm
• Mechanical steering cable
• Hydraulic steering components
• KNOB21 speed knob
• Dashboard mounting components for the steering helm

Which Steering Helms Are Compatible?

The Ultraflex V23 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 helm manufacturer permits a 400mm / 15.7in steering wheel
• The dashboard provides clearance for the 400mm wheel diameter
• The installation provides clearance for the 110mm wheel depth
• The existing helm shaft, shaft key and retaining hardware are serviceable
• The wheel can turn through the complete steering range without contacting controls, instruments or the dashboard

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

Which Model and Accessory Options Are Available?

• V23 / 32397D: Five-spoke stainless-steel steering wheel with wood centre cap
• KNOB21 / 42371A: Optional speed knob listed for the V23 steering wheel

The KNOB21 speed knob is a separate accessory and is not included with the steering wheel.

Dimensions and Fitment

• Overall diameter: 400mm / 15.7in
• Depth: 110mm / 4.33in
• Hub taper: 19mm / 3/4in
• Number of spokes: Five
• Grip material: Stainless steel
• Spoke material: Stainless steel
• Centre-cap material: Wood
• Hub: Included
• Helm compatibility: Compatible standard marine helms with a 3/4in tapered shaft

The 400mm wheel diameter and 110mm depth must be checked against the available space at the helm station before installation.

Construction and Design

• Five-spoke marine steering-wheel design
• Non-magnetic stainless-steel construction
• Stainless-steel grip
• Stainless-steel spokes
• Wood centre cap
• Included mounting hub
• Circular marine steering-wheel profile
• Optional speed-knob compatibility
• Designed for compatible standard marine helm installations

The stainless-steel grip and spokes provide a metal steering-wheel structure for marine installations. The wood centre cap covers the central hub area and provides a contrasting finish.

The optional KNOB21 speed knob can be fitted where a steering-wheel spinner is required. Its suitability must be considered in relation to the boat, helm layout and applicable operating requirements.

Standards and Certification

Ultraflex states that the V23 meets the following standards and requirements:

• EN 28848
• EN 29775
• ABYC P22
• UKCA requirements

The manufacturer lists the following certifications and markings:

• CE
• NMMA
• UKCA

Installation must still comply with the instructions, maximum steering-wheel dimensions and operating limits specified for the steering helm and complete steering system.

Installation and Use

Confirm that the steering helm has a standard 19mm / 3/4in tapered shaft and is approved for a 400mm steering wheel 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. Do not force an incompatible hub onto the shaft or alter the taper to make it fit.

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
• The shaft key and retaining hardware are correctly installed
• The wood centre cap is correctly secured
• The steering system reaches both limits without binding

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.
