摘要： A marine drive has a reverse thrust cup on the propeller shaft between the propeller hub and the rear retaining nut. The reverse thrust cup permits the propeller hub to slide on the propeller shaft fore and aft. When the marine drive is in the forward direction the rearward thrust of the propeller forces the propeller hub to the forward position thereby directing engine exhaust out the rear of the propeller hub. Conversely, when the marine drive is in the reverse direction, the forward thrust created by the propeller hub forces the propeller hub to the rearward position thereby directing exhaust out a forward exhaust opening forward of the propeller blades increasing the reverse thrust of the marine drive.

摘要： A marine trolling propulsion system (2) has a lower submerged housing (4) including an electric motor (5) driving a propeller (6) through a reducing traction drive provided by rolling contact of threee balls (57-59) between split inner races (36 and 38) and an outer race (60) to drive a transfer member (68) which rotates the propeller (6). The inner race halves (36 and 38) are axially loaded by Belleville washers (72) providing constant axial force with axial deflection, and a limited maximum loading force capability to intentionally provide overload slip protection. The inner race halves (36 and 38) are keyed to the intermediate floating shaft (14) on raised hexagonal shoulders (32 and 34) permitting rocking of the inner race halves (36 and 38) and self-seating and alignment of the inner race halves to the balls (57-59). Couplers (16 and 124) are provided between the electric motor shaft (12) and an intermediate floating axial shaft (14) and between the transfer member (68) and the propeller shaft (70) which enable different axes of rotation to accommodate manufacturing variations. The transfer member (68) is also coupled to the propeller shaft (70) by structure (118, 126, 128) enabling the transfer member (68) to rock about the center of the propeller shaft (70) such that propeller thrust is transmitted equally to the balls (57-59).
