I just bought a NFB (No-Feed Back) helm and cannot turn the shaft by hand. Why?
Without the steering wheel on the shaft, NFB helms are very difficult to turn by hand. This reason is the No-Feed Back clutch is always on “standby” to grip the helm shaft and hold it steady against torque feedback from the engine (which can make the steering wheel turn on non-No-Feedback systems). Once the helm is mounted in the dash and the steering wheel is properly attached, you will be able to turn the shaft easily. Follow the installation instructions completely. NOTE: An overview of NFB can be found on page 23 in this catalog. Available NFB systems are shown after that.
