A bracket for mounting a thruster to a boat includes a horizontal portion, a vertical portion that provides a vertical surface that matches an angle of the vessel transom, generally. The horizontal portion includes an enclosure. The vertical portion forms a transom-facing surface in a plane that is generally at a right angle relative to a horizontal plane, within a small range of angles. The transom-facing surface can angled to match the angle of the transom of a boat to which the thruster bracket is mounted. A thruster is mounted to the thruster bracket on a rotatable thruster mount that allows the thruster to be rotated in a generally horizontal plane relative to the bracket and the vessel to facilitate low speed maneuvering.

An outboard motor stabilizer of unitary construction has a cylindrical body and an axially oriented cylindrical orifice with an opening at the bottom end of the body. The orifice has a diameter sized to fit onto a tilt rod of an outboard motor and is of a length that is longer than the tilt rod of the outboard motor.

An outboard motor includes an outboard motor body that, when located in a full trim-in position, an upper connecting pin is located in a lower limit position below a tilt shaft. When the outboard motor body is in a full tilt-up position, the upper connecting pin is located in the upper limit position above the tilt shaft. The upper connecting pin rotates around the tilt shaft at a first rotation angle from the lower limit position to a horizontal position at the same height as the tilt shaft. The upper connecting pin rotates at a second rotation angle around the tilt shaft from the horizontal position to the upper limit position. The second rotation angle is larger than the first rotation angle.

A trolling motor mounting bracket (1) which can be adjustably attached to a boat by a quick release handle (14) having pins (18) inserted through a chock (20) attached to the boat. The bracket has a support arm (4) with cradle rest (11) for supporting a shaft (18) of a trolling motor (6). The support arm be attached to the bracket by a hinge (10) which may have a spring that can be adjusted by a set screw (33) to increase resistance in the trolling motor support arm. A recessed cavity (24) in a base (31) of the bracket allows the bracket to be positioned variably on the chock.

An outboard motor includes a transom clamp bracket configured to be supported on a transom of a marine vessel and a swivel bracket configured to be supported by the transom clamp bracket. A propulsion unit is supported by the swivel bracket, the propulsion unit comprising a head unit, a midsection below the head unit, and a lower unit below the midsection. The head unit, midsection, and lower unit are generally vertically aligned with one another when the outboard motor is in a neutral tilt/trim position. The propulsion unit is detachable from the transom clamp bracket.

A hybrid ship propulsion machine includes an internal-combustion-drive propulsion part, a fixing bracket configured to fix the internal-combustion-drive propulsion part to a ship, an electric propulsion part, an elevating device configured to elevate and lower the electric propulsion part; and an attachment bracket attaching the electric propulsion part and the elevating device to the fixing bracket. The elevating device is configured to elevate and lower the electric propulsion part between a position where a second propeller of the electric propulsion part sinks below a water surface and a position where the second propeller comes out of the water surface.

An outboard motor includes an outboard motor main body, a support including a tilt shaft and that supports the outboard motor main body, and a trim cylinder including a first trim cylinder shaft disposed below the tilt shaft along an outer surface of a transom of a hull. A distance between the tilt shaft and the first trim cylinder shaft is adjustable.
