Good catch Jim, oddly though in the Unit 2 manual ( the type on my boat) it doesn't specifically state to use any lube (McLube to be specific) although it does show a photo of what looks like lube being applied? Weird, I do not recall anything in my manual on the boat saying anything other than soapy water rinse twice a year.
Keep unit clean. When you wash boat, flush unit with soap and fresh water.
Occasionally lower sail and flush halyard swivel with soap and fresh water.
Clean unit more thoroughly at least twice a year. First remove line (note
direction on spool) and flush bearings with soap and fresh water.
