Compatibility / Fitment Guide
Direct fit criteria: steering helm with a standard 3/4in tapered shaft, compatible key/nut arrangement, and a manufacturer-permitted wheel diameter of at least 400 mm. Check spoke/rim clearance to the dash, throttle and windscreen through the full rotation.
Examples: the Ultraflex T85 mechanical system permits up to 406 mm, so V23 is within its diameter limit when the taper and installation geometry match. Other Ultraflex, Teleflex/SeaStar or hydraulic helms may share the taper, but their shaft, keyway, nut and maximum-wheel specifications must be checked individually.
Not compatible without an adaptor: splined, keyed straight-bore or non-3/4in helm shafts. No adaptor is included or implied.

Frequently Asked Questions
Will it fit a T85 helm?
The T85 allows up to a 406 mm wheel and uses the standard 3/4in taper; confirm the complete shaft hardware and clearance.
Is 400 mm the hole size?
No. It is the overall wheel diameter.
Will it fit every SeaStar helm?
Not automatically. Verify the exact helm shaft taper, keyway/nut and permitted diameter.
Is an adaptor included?
No adaptor is specified.
Important: Use the helm manufacturer’s washer, key and retaining-nut procedure. Recheck torque and free movement after installation.
