Does anybody know the specified size for the flax packing for the rudder post? I am trying to find out prior to hauling and taking the old packing out.
Kind of hard for anybody to answer that when you don't tell us what make/model the boat is, much less the rudder post size.
Unless TOCK is a specific boat?
No way to tell man... Unless you give us a boat to help you research....
Barring that... measure your shaft and housing.... Buy 3-4 sizes that seem reasonable, and return the rest... Don't know your finances, but most likely would not have to take out a loan....
