Anyone know of a good source for a replacement Autohelm 3000 autopilot belt? I need the B- size. That's the one used when the distance between the center of the wheel and the mounting pin on the clevis is 20.1 inches. West Marine only lists a different size and Raymarine wants $36 or so for one. I was hoping someone might know of a source of the B- belt at less cost. I know the Autohelm 3000 is outdated technology, but like myself ... it's old but still working. Thanks, Gary Kunkel
