I am currently sailing on SPIRIT GUIDE, a 2002 Super Maramu #348 (ex- CHANCE), owed by Matthew and Lori Moore. We have just started experiencing a problem with the drop and lift motor of the bow thruster. The bow thruster won't go down by itself after operating the cockpit switch unless we give the lift motor/electrical box a sharp tap then it operates as usual. It also sticks in the down position. We have checked all the wire terminals in the attached control box and believe all the wires to be OK and the connections good. The motor itself seems to require special tools to check the brushes.
We suspect either the motor brushes or relay in the control box to be the problem.
