While motoring out of my marina, I noticed the boat failing to respond to steering wheel inputs from the port helm. Luckily I was able to steer the boat from starboard wheel. Turned out that rod connected from port wheel mechanism to rudder quadrant had come apart. In port I was able to re-connect and tighten jam nuts with blue Locktite applied. I would suggest that all Hunter 49/50 owners , and everyone else with a Lewmar Mamba steering system check the tightness of the four jam nuts.
