To follow up FYI, we're on the hard
now and have had the lower "collar" removed on both huls. The mechanic
had to cut the old collars out because the old ones appeared to be epoxied into the hull
. After removal
there was some minor fiberglass repairs
, and the mech re-installed using epoxy
. This change out is not easy (about 8 hrs work) but is not the end of the world.
The reasons we did this change:
-There is lateral movement of the stbd rudder
- probably 1/4 to 3/8". We replaced the bearing (white delrin (my guess) ball hole for rudder shaft. When the old one was removed we could see the collar (my name) had corrosion
- We didn't know the status of the port bearing and collar, and there was only minor lateral movement.
- When the bearing was removed 3 months later it clearly had a lot of scaring from the collar.
- We went ahead with the removal
and replacement on both sides as repair and preventive.
BTW, both of the SS set screws that hold the top of the rudder shaft had to be removed by ez-out. Each had corroded and welded into the aluminum
rudder arm. The set screws are 10mm dia, 20mm long, 1.5 pitch
, cup style end (not conical end but more pyramidal with a small flat end) if you need to purchase
