[0002] Baiting boats are an effective tool for assisting fishing. When fishing in reservoirs or relatively open waters, it is impossible to place bait in suitable locations by manpower alone, but baiting boats can effectively solve this problem.

[0003] Existing remote-controlled baiting boats generally consist of a hull, feed bin, battery, motor, propeller, and controller. The motor drives the propeller, propelling the boat forward or backward. The direction of movement is controlled by the remote control, which can also be used to pour bait into suitable waters. However, existing baiting boats typically house the motor inside the hull for waterproofing purposes. Placing the motor externally would improve heat dissipation. Currently, a solution to the waterproofing issue is needed for externally mounted motors. Summary of the Invention

The protective cover 44 is located outside the propeller 42. The motor housing 43 includes a housing body 431, a rear cover 432, a positioning member 439, and a sealing sleeve 433. The housing body 431 and the rear cover 432 are fixedly connected. The fixing member 442 includes a bottom wall and an annular side wall. The positioning member 439 is fixed inside the rear cover 432, and a gap is reserved between the annular side wall and the side wall of the rear cover 432. The sealing sleeve 433 is located between the positioning member 439 and the rear cover 432. The housing body 431 extends into the gap between the rear cover 432 and the positioning member 439 and presses the edge of the sealing sleeve 433. Because the positioning member 439 is provided, the sealing sleeve 433 can be pressed tightly, and the sealing sleeve 433 will not shift. Compared with the previous device without the positioning member 439, this structure is more stable. Moreover, the positioning member 439 pressing the sealing sleeve 433 can also ensure that the sealing sleeve 433 better seals the shaft hole of the rear cover 432.
