         5 . The electric outboard motor according to  claim 4 , wherein an upper end surface of the motor is positioned lower than an upper end surface of the controller. 
     
     
         6 . The electric outboard motor according to  claim 1 ,
 wherein the outboard motor body comprises a cover that houses the motor and the controller,   wherein the controller is located behind the motor,   wherein there is a space between an inner surface of the cover and a side surface of the motor,   wherein the hull is equipped with a battery, and   wherein a DC cable that extends from the battery through the space to the controller is provided.   
     
     
         7 . The electric outboard motor according to  claim 1 ,
 wherein the outboard motor body comprises a cover that houses the motor and the controller,   wherein the cover has an upper part having a bulge protruding upward,   wherein the bulge has an inner side forming a space,   wherein the hull is equipped with a battery, and   wherein a DC cable that extends from the battery through the space to the controller is provided.   
     
     
         8 . The electric outboard motor according to  claim 1 , wherein the attachment supports a portion of the outboard motor body above a center of gravity of the motor, and a portion of the outboard motor body below the center of gravity of the motor. 
     
     
         9 . The electric outboard motor according to  claim 1 ,
 wherein the attachment comprises an L-shaped bracket in side view comprising a vertical part extending in a vertical direction and a horizontal part extending rearward from a lower end of the vertical part, and   wherein the bracket supports the outboard motor body.   
     
     
         10 . The electric outboard motor according to  claim 1 ,
 wherein the outboard motor body comprises a cover that houses the motor and the controller, and   wherein the cover has an upper end located above the upper end of the rear surface of the portion of the hull to which the attachment is attached.   
     
     
         11 . The electric outboard motor according to  claim 1 , wherein at least one of the motor or the controller is provided so that an upper end surface thereof is horizontal. 
     
     
         12 . The electric outboard motor according to  claim 1 ,
 wherein the controller comprises a control circuit configured to control the motor, a controller case that houses the control circuit, and a controller connector provided in the controller case,   wherein the motor comprises a rotor, a stator configured to rotate the rotor, a motor case that houses the rotor and the stator, and a motor connector provided in the motor case, and   wherein the controller connector and the motor connector engage with each other to electrically connect the controller and the motor.   
     
     
         13 . The electric outboard motor according to  claim 1 ,
 wherein the electric outboard motor further comprises a heat exchanger extending below a water surface on which the hull floats, and   wherein the heat exchanger cools a cooling target by discharging heat generated in the cooling target including at least one of the motor or the controller to water below the water surface.   
     
     
         14 . The electric outboard motor according to  claim 1 ,
 wherein the electric outboard motor further comprises a drive shaft for transmitting power of the motor to the propeller,   wherein the outboard motor body comprises an upper unit comprising the controller and the motor, and a lower unit comprising the propeller, and   wherein the lower unit rotates about an axis of the drive shaft relative to the upper unit at a time of turning to change a traveling direction of the hull.   
     
     
         15 . A vessel comprising:
 the electric outboard motor according to  claim 1 ;   the hull;   a hull deck overlapping at least a portion of a rear part of the hull in top view; and   an outboard motor deck provided above the outboard motor body and overlapping at least a portion of the outboard motor body in top view.
