The original system was 3.0 turns lock to lock so I didn't see any reason to go to the 4.2. Also the 3.0 system is good for motors to 150HP. I don't think the V-20 is a hard boat to steer so why would you need the greater ratio? I went to the anti-feedback system because I thought it might make chasing the birds in Raritan Bay a little easier and it would make it easier for my young sons to keep a heading. We'll see. Sorry I didn't take any pictures while doing this. There are two tricky issues, one is getting the new cable into the tilt tube without removing the motor and the other is that the new system comes with a verticval helm bracket instaed of the 20 degree tilt required. You can get by by modifying the original bracket or maybe Tele-Flex makes the right bracket, I don't know.
