Independent rotation control of sonar and trolling motor

A combined sonar and motor assembly comprising:

• a sonar transducer assembly;
• a propulsion motor;
• a first shaft defining an axis;
• and
• a second shaft that is hollow and that defines an opening,
• wherein the first shaft is received within the opening of the second shaft, wherein the propulsion motor is attached on the first shaft, wherein the sonar transducer assembly is attached on the second shaft, and wherein the second shaft is configured to rotate relative to the first shaft about the axis to enable a rotation of one of the sonar transducer assembly or the propulsion motor about the axis without rotating the other, and wherein the sonar transducer assembly and the propulsion motor are both configured to rotate about the axis.

A method of assembling a combined sonar and motor assembly for a watercraft, the method comprising:

• providing a first shaft that defines an axis, wherein the first shaft defines a first end and a second end;
• providing sonar transducer assembly, a propulsion motor, and a subassembly, wherein the subassembly defines an opening therein;
• attaching the sonar transducer assembly to the subassembly;
• attaching the propulsion motor to the first shaft proximate to the second end of the first shaft;
• and
• receiving the first end of the first shaft through the opening of the subassembly,
• wherein the first end of the first shaft is received through the opening of the subassembly so that the first shaft is allowed to rotate about the axis and so that the sonar transducer assembly is rotatable about the axis relative to the propulsion motor.
