I've got two seldom-used Worth Anchormate 2's on my boat, and they must be almost 20 years old. They reel in fine, but have started sticking when releasing/dropping the anchors. Anybody have experience troubleshooting and repairing these? I am assuming it's lubrication failure, or possibly springs have weakened. I found a Worth video showing basic disassembly and reassembly, but with no detail about what to look for in terms of troubleshooting. New reel units are available for $70-100 apiece, but if I can fix these via lubrication, etc, I certainly would. Externally they look very clean.
