Disclosed are a thruster system and a vessel including the same. The thruster system according to an exemplary embodiment of the present invention includes: a canister on which a thruster is installed, and which is movable upward and downward in a hull; a wire controller which controls a wire connected with the canister and enables the upward and downward movement of the canister; and a ballast tank which is installed in the canister and filled with water in order to offset the buoyancy that is applied to the canister.

An outboard motor mounting apparatus for outboard motors that control the outboard motor propeller thrust line angle of attack through a larger range than is currently available in practice today, including afterplanes (hydrodynamic lifting surfaces) in order to create boat stern lift. The afterplanes move to provide lift with a trimmable hinged portion in combination with movement of the outboard motor propeller thrust line.

An actuator for imparting steering movement to a tiller of a propulsion unit of a marine vessel comprises an absolute position sensor which senses a steering position and a relative position sensor which senses a position of the motor. A steering control unit calibrates the relative position sensor based on a signal of the absolute position sensor. Calibration of the relative position sensor based on a signal of the absolute position sensor initializes an accumulative position which accumulates a relative position as the actuator moves over time.

A trolling motor assembly may be pivotable between a stowed position and a deployed position. The trolling motor assembly may include a trolling motor subassembly comprising a shaft and a motor coupled thereto. The subassembly may be pivotable about a base via a linkage. The linkage may include a first arm having a first end and a second end, wherein the first end of the first arm is coupled with the base, and the second end of the first arm is coupled with the shaft. A first biasing element may be coupled with the linkage so that the biasing element is configured to apply a first force to the linkage that biases the linkage in a raising direction from the stowed position in order to assist a user in deploying the trolling motor into the water.
