An underwater propulsion unit (1) includes a propeller (11), a motor (12), and a housing (5). The motor (12) is disposed further forward in a propulsion direction than the propeller (11) and drives the propeller (11) into rotation. The housing (5) that accommodates the motor (12) and the propeller (11) includes a first portion (5a) and a second portion (5b). In the second portion (5b) disposed further rearward in the propulsion direction than the first portion (5a), an introduction inlet (21) and a spout outlet (22) are provided. The introduction inlet (21) introduces water into the housing (5). The spout outlet (22) allows water introduced from the introduction inlet (21) and delivered by the propeller (11) to be spouted outside the housing (5). When viewed in a direction parallel to the propulsion direction, the introduction inlet (21) is disposed further outward than the first portion (5a). The introduction inlet (21) introduces water into the housing (5) in a direction parallel to an axis (11c) of the propeller (11).
