C34 Mk II, # 1472, has a the original Edson Wheel with a Raymarine 4000 Wheel Pilot. Works fine. I acquired a brand new leather covered wheel. New wheel is correct 40" dia. and shaft size, etc. However, the new wheel has 5 spokes (6 on the old one) , the new spokes are tapered (thicker at the hub-thinner at the rim) and the wheel has a slight dish to it (the hub is further forward - the old wheel is flat). You can't retro fit the 4000 to the new wheel because of the taper and the "dish". Raymarine has discontinued the 4000 and parts. I'll go for a new X5 wheel drive, but when I called Raymarine they were more than hesitiant about telling me it would fit a wheel with a "dish" and suggested "some custom fit" work. Anyone got a 5 spoke Edson with a dish and an X5 pilot? If so how dfoes it fit and what do I order from Raymarine. Thx all.
