Hello all, I'm coming to near completion of my Dumas Drag'N Fly 20. Now I need to get the running hardware. What diameter should I be using for the flex shaft? Should I use .150 or .187 (3/16) size cable? The original called for a 3/16 solid shaft, so I'm assuming that I should stick with that size for the flex cable. Also, how do I install the flex shaft though the hull? Do I use a stuffing tube with bushings/needle bearings at the ends? Or do I use a Teflon tube and run that through a stuffing tube? Or just the Teflon liner goes through the bottom of the hull? Too many ways to do this I guess. Any input from anyone who has installed a flex shaft though the bottom of the hull would be very appreciated. I want to keep this boat as stock as possible with regards to the strut. The original strut was to be mounted underneath the boat forward of the transom. All the strut hardware I've see from other manufactures mount the strut to the transom. There is only enough room to mount the rudder on the transom. I've check out Prather and Octura hardware and they all seem to mount on the transom. Dumas is the only manufacture I've seen that will mount the strut under the boat (it comes up through and attaches between 2 brackets). Turn Fin?? What size should it be? Lenght I mean. Dumas makes one, but does not show the size. Just wondering what size from other manufactures would work. Oh, and the engine that I will be using will be an O.S. .15 CV-MX. I know I will need a flywheel for this as well as a collet for the flex shaft. Any idea about who makes a collet for this engine? Thanks in advance for all your help!
