A marine propeller (10) with an adjustable exhaust structure is disclosed. Each adjustable exhaust device (30) of the adjustable exhaust structure includes an exhaust hole unit (40) with exhaust through holes (46) cut through the outer surface (226) and inner surface (228) of the propeller hub (22) of the marine propeller (10), an adjustment member (50) with shielding portions (548) mounted in the exhaust hole unit (40), and a fastening member (60) for securing the adjustment member (50) in position. The adjustment member (50) is movable to adjust the shielding area of the shielding portions (548) relative to the exhaust through holes (46) when disengaged from the constraint of the fastening member (60). Thus, the exhaust volume is adjustable to fit different conditions without changing any component parts of the marine propeller (10), facilitating ease of use of the marine propeller (10). |
