In looking for the means to lubricate my rudder
post this is what I found. It appears to be where I would lube but being so covered in rust I'm not sure how it functions. For scale, the larger diameter is about 1.25". Probably the whole thing unscrews but didn't want to attempt removal
without asking opinions as it's near the waterline. Not likely there's water
in there but didn't want to take the chance.
It's on a '79 C&C38. When I do get it opened/off any opinion on what lubricant and method is recommended would be appreciated.
