Abstract
A marine propulsion apparatus including a first strut and a second strut, each extending from a proximal end to a distal end, wherein the proximal ends of the first and second struts are coupled to an anti-ventilation plate, a lower unit coupled to the distal ends of the first strut and the second strut, the lower unit the lower unit housing a sprocket, a shaft rotatably coupled to the sprocket, a propeller coupled to the shaft proximate the tail portion of the lower unit, the propeller configured to rotate with the shaft, a belt rotatably coupling the drive shaft to the sprocket, wherein the belt is disposed within the interior belt voids of the first and second struts; and at least one thermal circuit channel extending through a portion of the anti-ventilation plate, the at least one thermal circuit configured to channel a coolant to flow therethrough.
