Steering wheel Speed Knobs for Docking

[SLyle01]

Per Andrew's suggestion on "Ad the Prop Turns, close in maneuvering..", where can we buy a 'speed-knob' for our 2019 RT27 OB steering wheel. One that had been suggested previously, we bought (on Amazon, $18) bit it's too small to clamp-on.
Is the 2019 wheel a different size than the 2018 wheels? What IS the actual wheel diameter?
THANKS for the Seminars!

Hello,

The knob should have a few different rubber sleeves for different size wheels. I believe I only used one of them on the 2018 R-27. However, all the wheels have been the same size so it should fit.

The wheel diameter is 1 1/4 inches. Or more exactly 31 mm. which equates to 1.22 inches.
