I am going up the mast Saturday to find out why my masthead unit got stuck in one position. The instructions say to lubricate every year. I doubt it has ever been done. The unit is an Autohelm unit (pre Raymarine). The unit is obviously stuck as it only shows the one direction ( about 140 degrees off boat heading ) and I can see it isn't rotating to the prevailing wind from the dock. I plan on going up with a few tools and some McLube or silicone spray with a back up of a WD 40 type lube as a last resort. Any suggestions would be appreciated. Thank you in advance. We got the boat last year and it just never made it onto the "Have to get this done" list until now when it quit working.
