- C&C 34+ Rudder Support Question... - 6 Updates
Richard Servance <hics...@gmail.com>: Jan 29 09:27AM -0800
Yes, dissimilar metals. The old idler plate is mild steel, while all the
other components are aluminium. The reason the newer idler plates need
modifications is that they are now aluminium and thicker. Now that I can
see it, I can confirm that the 4 aluminium bolts thread into fittings
bedded into the fiberglass. I'm hoping I get away without needing to cut
into the aft cabin headliner, which is a fully one piece and seamless thing.
As to the cable routing, I took video as I was disconnecting it to make
sure I got the cross over locked into memory.
Back at it after work today.
Sail safe,

Richard,
I have seen a number of owners that cut into the aft headliner and simply covered the hole with a small plate that can easily be removed at a later time if needed. I seriously doubt you will be able to remove those bolts without acscees below. I'll see if I saved any picks from past posts and send them to you.

I used a 5 or 6” hole saw to access in the aft cabin. I drilled it on the side so you really don't notice it and installed a screw cover access plate.

I would love to, but with this Artic air, I haven't seen my boat in weeks.
Here is some pictures to explain.

Hi Tim,
That helps a lot. I'm trying to understand better.
Do your pedestal bolts and guard bolts penetrate through the deck like on
my R model?
Can you access nuts on the other side of the deck well?

Hi Richard- I also thought that forward should be up, so I reversed the transmission by detaching the cable where it attached to the transmission arm and rotating the arm. If I remember correctly, it was set up so the cable attachment arm pointed down and now it points up. Could be the other way around. It took a bit of trial and error to find the exact angle that worked for both forward and reverse. Dave
