    Abstract: A marine propulsion system includes an engine, propellers arranged to be rotated by the engine, a transmission mechanism arranged to transmit a driving force of the engine to the propellers with a speed thereof shifted to at least a low speed reduction ratio and a high speed reduction ratio, a GPS sensor arranged to detect a position of a hull propelled by rotation of the propeller, and a control portion and an ECU arranged to control a shift between the speed reduction ratios of the transmission mechanism. The control portion is arranged to calculate a speed of the hull based on positional information of the hull. The control portion and the ECU are arranged to control a shift between the speed reduction ratios of the transmission mechanism based at least on the speed of the hull. This arrangement provides a marine propulsion system in which both acceleration performance and maximum speed can approach specific levels desired by an operator of the boat.

    Abstract: In an outboard motor having a power transmission mechanism for transmitting power of an engine to a propeller, the power transmission mechanism has a transmission ratio changing unit having a planetary gear train including a sun gear, planetary gears, and an internal gear. The internal gear is connected to an input side shaft on the engine side. The planetary gears are connected to an output side shaft on the propeller side. The sun gear is connected to a stationary portion via a one-way clutch. The planetary gears and the internal gear and/or the sun gear are connected by an on-off clutch. When the on-off clutch is disengaged, the one-way clutch is engaged and the speed from the input side shaft is outputted from the output side shaft with a reduced speed. When the on-off clutch is engaged, the speed from the input side shaft is outputted from the output side shaft with the same speed.

    Abstract: An electric trolling motor includes a lower unit with a cylindrical motor housing closed at the aft end by a planetary gear-reduction subassembly including a cup-shaped end bell housing. A motor shaft hub member telescopes into the housing and clamps against an annular gear with clamping bolts passing therethrough and threaded into the hub member. Planetary gears carried by a cage engage the annulus gear. A propeller shaft is fixed to the cage and journaled in a hub portion of the housing. A sun gear meshes with the planetary gears and has an opening aligned with an opening in a hub portion of the hub member to receive the motor shaft. The shaft openings in the gear housing and in the hub member have shaft bearings in spherical seats and rotating seals. The subassembly drops onto the motor shaft with the gear housing abutting the motor housing and secured thereto by bolts. The motor shaft and sun gear have complementing interlocking surfaces to establish rotatable interconnection. The opposing surfaces of the sun gear and the cage have thrust bearing surfaces with the motor shaft holding the sun gear in cage abutting relation. The propeller unit includes a hub which telescopes over the hub portion of the housing which is of the same diameter as the housing to form an extension of the housing to minimize weed entanglement. A pair of large diameter propeller blades project from the hub and are swept back in the direction of rotation.
