I haven't experienced a rudder post leak on either of my AMELS (16 yrs a
Maramu and now 4 years with a Super Maramu), but I have heard it can happen. The
rudder bearing is like a sterngland on the prop shaft. You should be able to
see if it is leaking when you sail. If it is you should repack it at your next
haulout.
