With a vary big rudder the radius came down to about 10 feet. With a rudder on 7 of 8 tubes the radius came down to about 3 feet which could be OK but it really hurt the power slowing the boat by more than half. (See my photos.)

Attaching siliconhose to the exhausttubes so that they can move with the rudders might work. (Not tried it yet)
Thanks for the update. SOunds like an interesting project. Keep us posted.
