C&C 33 rudder post lubrication
On July 13, 2009 Keelcooler posted a response to a tread about lubricating fittings on C&C 33 rudder posts, stating that most lubricating fittings on these boats he has seen were of ferrous metal and badly rusted. I have discovered mine which seems to have been a grease cup type but it is almost completely rusted away. Any ideas about replacement? My boat is afloat. Is this fitting above the water line? How concerned should I be?
Thanks, SLY guy. |

I would *strongly* suggest the C&C mailing list for this question. There is a TON of expert advice there. The sign-up is here:

Grease cups are fine if you have access to them to give them a turn. The alternate is a zerk fitting that you have to get a grease gun onto. I know zerk fittings are available in many materials - in my working days we installed many Ni-Cu (Monel) zerk fittings on Navy ships. I doubt grease cups are available in non-corrosive materials. In many cases the zerk fitting we installed was remote from the bearing, connected by suitable high pressure tubing (think of bearing for a submarine periscope - zerk fitting inside the people tank). For things such as a rudder tiller pin, the remote tubing would have to be partly flexible to allow the rudder to move without breaking the tubing.
