An outboard motor includes an outboard motor main body including an engine and a propeller driven by the engine, an upper bracket to attach the outboard motor main body to a hull, and a pair of antivibration mounts. The pair of antivibration mounts are joined to the upper bracket, and sandwich and elastically support a portion of the outboard motor main body from the left and the right of the outboard motor main body. The pair of antivibration mounts are arranged side by side in the left-right direction so that a center of rolling of the outboard motor main body is located between the pair of antivibration mounts in the left-right direction, and are bilaterally asymmetrical to each other.

A stern drive is for propelling a marine vessel in water. The stern drive has an upper drive unit with a lower mounting surface; a lower gearcase coupled to the lower mounting surface and a trailing end surface that is angled relative to the lower mounting surface; and a propeller shaft extending forwardly from the lower gearcase and being configured to rotate a propeller for pulling the marine vessel in the water. The upper drive unit and the lower gearcase are configured such that when a forward side of the lower gearcase impacts an underwater obstruction, the lower gearcase is caused to pivot relative to the upper drive unit until the trailing end surface impacts the lower mounting surface, which thereby causes the lower gearcase to completely uncouple from the upper drive unit.

A personal watercraft body comprises a recess configured to receive similarly shaped cassettes. A first cassette may be motorized to propel the body relative to a body of water. A second cassette may be non-motorized and may include a storage space therein for storing personal items. An insert may be disposed between the cassettes and the recess to orient and fit the cassettes within the body.

A compressor module (1) comprises: a floor member (3); a gas cooler (24) mounted on the floor member (3); a compressor skid (10) disposed on a side of the gas cooler (24) opposite to where the floor member (3) is located, the compressor skid (10) being connected to the gas cooler (24); and a leg portion (15) connected to the compressor skid (10) and fixed to the floor member (3) that supports the compressor skid (10), the leg portion (15) providing a gap to dispose the gas cooler (24) between the floor member (3) and the compressor skid (10).

A bracket for mounting a thruster to a boat includes a horizontal neck portion, an upper mounting support portion, a support plate portion that extends downward from the upper mounting support portion, and an enclosure portion. The support plate portion and the rear of the upper mounting support portion form a transom-facing surface in a plane that is at a non-right angle relative to a horizontal plane. The transom-facing surface is angled such that the bottom of the support plate portion is further to the rear of the thruster bracket than the top of the upper mounting support portion in order 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 at a level where the thruster will be out of the water when the boat is moving fast and up on plane, and will be in the water when the boat is moving very slow.
