New cable / sprocket fan steering is complete. tested it out last night and works perfect. at full throttle I can still turn the fan all the way around with one finger. Before at full throttle, I couldn't even turn the fan at half throttle with the push/pull. for the cable / sprocket setup, I used 3 pillow blocks on the steer stick, and 3 on the fan stand itself. on both shafts, there are pillow blocks attacked to the boat itself. By attaching to the boat, you transfer a lot of the forces directly into the boat, the most structurally sound object on the boat obviously.... I believe this is why it steers so easy, instead of the shafts binding due to the deck or fan stand stand moving, most of the forces are transfered to the bottom pillow blocks attached to the boat, which does not move at all. this allows the shafts to spin much easier. Maybe I am wrong, but this is my thought, and it works great. For the rest of the parts, I used 1" solid shaft for the fan, and 1" structural tubing for the steer stick. I used 6" diameter, #40 sprockets on both the fan shaft, and steer stick, as well as 1/8" galvanized cable. I don't see any reason to go larger than 1/8". the cable is rated for almost 400#... any larger will just make steering much more difficult. For pulleys, I used simple garage door pulleys I bought at menards. Here are some pics of the final setup
