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