What Is This Steering Wheel Used For?

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.

The Ultraflex V57B is supplied with:

• Ultraflex V57B 38155O steering wheel
• Standard 3/4in tapered hub

Not included:

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

Which Steering Helms Are Compatible?

This steering wheel 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 dashboard and helm station provide clearance for the 350mm / 13.8in wheel diameter and 76mm / 3.0in depth
• The existing helm shaft, 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.

Standards and Certification

• ABYC P22
• UKCA requirements
• CE, NMMA and UKCA certifications / markings

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.
