For those skippers who are asking about Servo City arm winches, here is the information. Servocity contact information, email Sales@ServoCity.com phone 620-221-0123. Rudder servo is an HS-755HB, gear ratio is 7:1,TM-SG 20-70 servo gearbox in stock rotation. You must specify that you want the winch programmed for 180 degrees of rotation. This will produce about 32304oz-inches of torque which is plenty for the large J models. Power is provided from a 6V gel cell battery and you must use a Y harness to get full power to the winch. The cost of the winch assembled is about $260. Just a personal observation, it is well worth the assembly fee to have them do the assembly.
SG20-70 Series Servo Gearbox (7:1 Ratio, 360° Rotation, 3304 oz-in, 0.98 sec/60°)
All top mount gear boxes have been discontinued and replaced with a universal Channel mount gearbox
