Transducer mount system

A motor assembly for rotating a mounted device around a troll motor shaft underwater, comprising:

• a hub fix part having an O-ring shape and split into two separate halves;
• a top ring having an O-ring shape and split into two separate halves configured to be placed below the hub fix part;
• a gear ring having an inner surface covered with a plurality of gear teeth and split into two separate halves configured to be placed below the top ring;
• a bottom ring having a ring shape and split into two separate halves configured to be placed below the gear ring;
• a motor mounting plate having an O-ring shape and split into two separate halves configured to be placed below the bottom ring;
• a stepper motor attached to the motor mounting plate;
• a stepper motor shaft rotated by the stepper motor;
• and
• a spur gear pinion attached to the stepper motor shaft,
• wherein the hub fix part, the top ring, the gear ring, the bottom ring and the motor mounting plate are configured, when positioned on top of each other, to form an inner chamber in the motor assembly that allows the stepper motor to rotate the spur gear pinion inside the inner chamber, the spur gear pinion engages with the plurality of gear teeth of the gear ring to thereby rotate the motor assembly about an axis of the troll motor shaft.

A mechanism for rotating a mounted device around a troll motor shaft underwater, comprising:

• a mounting ring, comprising:
• an outer mounting ring having an outer surface and an inner surface covered with a plurality of outer gears, and
• an inner mounting ring having an outer surface and a cylindrical inner surface configured to be securely attached to a troll motor shaft;
• a mounted device coupler attached to the outer mounting ring and configured to securely attach to a mounted device;
• a plurality of support brackets configured to securely attach the mounting ring with a plurality of mounting hardware;
• and
• a motor operably connected to the mounting ring having a shaft and a gear configured to mesh with the plurality of outer gears and configured to horizontally rotate the mounted device attached to the outer mounting ring clockwise at a first time and counter-clockwise at a second different time about the troll motor shaft.
