 John S. & Bryan,
   Thanks for the gear info.  I located the gears at Martin Sprocket & Gear in
Sacramento,  They wouldn't sell direct but gave me a distributor, also in
Sacramento. (http://www.martinsprocket.com/   They have a store locator on
this site. )  I called Friday and the gears were in my hands on Monday
afternoon.  They came with 1/2" bore which I'm having a local machine shop
enlarge.  The dimension is a perfect fit when bored out to fit the distance
between my rudder tubes.
 
 Thanks  -  You guys are great!
