My recently purchased boat included this autohelm unit. Previous owner didn't use it, he stating it would not keep up in the chop of the Pamlico. I can see that fact being true but it would be nice to engage it for short periods of time to adjust sails, hit the head and etc. My question is this. I did a bench test, hooked it to 12v, it works great. However when I had it in standby mode the motor is still locked in place and not free wheeling. I could not turn it by hand, is it suppose to be like this? I noticed there seems to be a tension relief or adjustment on the motor, Does the belt tension have to be relieved to go in to standby mode? From what I've read about these units they are old but solid and reliable. Also does the belt tend to wear regularly, will probably get a spare just in case.
