Rudder bearings replacement

[Zanshin]

It might sound like a stupid question for those who know, but I have no idea how complicated and expensive it is to replace the rudder bearings on a 43' boat. My boat survey discovered this issue and I am trying to figure out whether the seller should take care of it or if I can do it (and change the selling price).
What needs to be done to replace the bearings - a haul-out and much labor? Simple wrenching while afloat?

You should get a quote from a good yard, who actually looks at the installation and quotes appropriately. Then double whatever they say, such quotes are rarely accurate, and decide whether you'd be happy eating that amount - if not push it back to the seller, it's all negotiable. But pay close attention to whatever time limit you have for terminating the deal due to survey issues - once you pass that date your leverage is gone. If necessary, submit the cancellation notice but include an offer to continue the deal if more time is provided.
My personal wild guess for this work on an unknown boat, would be $2-5,000.
If this is the only material issue found in the survey, that's pretty good, or the survey is pretty weak. Be sure to have an engine survey done, if you haven't.

In this case the seller has boatyard facilities (they are a large charter company) but I wanted to be prepared for them not wanting to do the work and dropping that off the price. There were over 20 issues on the survey, but that included things like replacement of light bulbs and double-clamping through hulls. The survey was very in-depth and I'm confident they found the major issues. The bearings probably received their damage at the same time as the bottom of the rudder - which needs to be glassed per survey I'll ensure that those repairs get done by the seller and can deal with mintor stuff like plastic covers and affixing air filters myself. Thanks!
