[C320-list] Edson Tiller Arm Connection Detail for Linear Drive, Size of Blocks Limiting the Rudder Movement

[Scott Thompson]

Dave: I believe my installation is completely consistent with the specs 
and description in the Raymarine installation manual. See in particular 
figures 4 and 6 in the manual at this link: 
http://www.raymarine.eu/WorkArea/DownloadAsset.aspx?id=1937. Raymarine 
specifies connecting the drive on top of the tiller arm, not inside of 
it. It isn't clear how one would do the connection "inside" using the 
Raymarine hardware. My recollection is that the mounting pin is 10 
inches from the centerline of the rudder shaft, per Raymarine specs for 
this drive, but I would have to go down to the boat to check this. I 
recall that the blocks limiting the movement of the ruder are about 
3/4", but again I would have to go to the boat to check. The boat is on 
the hard in Annapolis right now, and I am not going to be on board again 
for several weeks, but I will try to remember to make some measurements 
next time I visit.

If you are in the Annapolis area I'd be happy to meet you at the boat 
sometime this winter so that you could see the installation in detail. I 
do not have some of these details recorded because I hired a 
professional to do the installation.
