I finally got around to inviting a dear friend to help me get at my linear drive
unit so that I could fix it. At 5'2", Marion was able to get down in the engine compartment and make her way to the rudder
quadrant. As expected, removal
of the unit was not to be easy. The rusted clip that held the drive piston to the quadrant immediately snapped off and was impossible to extract with the unit in place. The attachment pin, bolted to the underside of the quadrant, had siezed up due to galvanic corrosion
, as had the bolts holding the other end of the drive to its bracket. After a couple hours, though, we were able to free things up and get the drive out. From that point, it was easy and straight forward to simply remove the two bolts that hold the cover, free the sticking brushes, clean out the carbon, etc., and put things back together. All's well.
You just have to wonder why Raymarine
is reluctant to share this easy proceedure. They are probably quite content having customers send in their units for the four or five hundred dollar flat rate service
fee to have the factory do ten minutes worth of work. (Once the drive was out of the boat, everything else was quick and easy.)
