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.

The present invention(s) relates to a structure and method for improved auxiliary thruster systems for marine and small vessels, including small fishing and pontoon boats. Under conditions of wind or rough waters it may be impracticable to employ the main drive of a vessel because it may provide more thrust and motility than needed and may not be fuel efficient for such purposes. The present invention(s) relates to auxiliary thrusting and maneuvering systems of marine vehicles which may be employed in addition or independently of main propulsion of the vehicle or craft that protracts and retracts a thruster assembly.

A marine propulsion support system includes a transom bracket, a swivel bracket, and a mounting bracket. A drive unit is connected to the mounting bracket by a plurality of vibration isolation mounts, which are configured to absorb loads on the drive unit that do not exceed a mount design threshold. A bump stop located between the swivel bracket and the drive unit limits deflection of the drive unit caused by loads that exceed the threshold. An outboard motor includes a transom bracket, a swivel bracket, a cradle, and a drive unit supported between first and second opposite arms of the cradle. First and second vibration isolation mounts connect the first and second cradle arms to the drive unit, respectively. An upper motion-limiting bump stop is located remotely from the vibration isolation mounts and between the swivel bracket and the drive unit.

An outboard marine propulsion assembly includes a marine drive having a supporting frame and a steering arm extending from the supporting frame, a transom bracket assembly, a swivel member seated in the transom bracket assembly, the swivel member being configured so that rotation of the steering arm relative to the transom bracket assembly rotates the swivel member relative to the transom bracket assembly to thereby steer the marine drive, an upper vibration isolating joint which couples the steering arm to the supporting frame, and a lower vibration isolating joint which couples the swivel member to the supporting frame.

The present disclosure relates to a ship's propulsion unit such as a ship's azimuthing propulsion unit. The propulsion unit can include at least one supporting metal sheet arranged between an support section of a shell structure of the propulsion unit and an cylindrical outer surface of a cylindrical section of a motor housing section of the shell structure for providing additional support for the motor housing section of the shell structure at the shell structure of the support section.

An arrangement is for coupling a vibration isolation mount to an outboard motor. A pocket is formed in a midsection housing of the outboard motor and defines a first concave surface. A cover is configured to be mounted to the midsection housing over the pocket via a plurality of fasteners. The cover defines a second, oppositely concave surface on an inner face thereof. When the cover is mounted to the midsection housing over the pocket, the first concave surface and the second concave surface together form a cavity therebetween for holding a vibration isolation mount therein. One of the first concave surface and the second concave surface has a protrusion that extends into the cavity and contacts the mount held therein upon tightening of the plurality of fasteners to hold the cover over mount in the pocket. A mounting arrangement is also provided.

A stern drive for a marine vessel comprises a gimbal housing that is configured for connection to the transom of the marine vessel; a gimbal ring that is steerable with respect to the gimbal housing about a vertical steering axis; a drive leg that is trimmable with respect to the gimbal ring about a horizontal trim axis, wherein the drive leg supports a propulsor for propelling the marine vessel; a trim actuator that is configured to trim the drive leg about the trim axis; and a cradle that decouples the drive leg from the transom of the marine vessel and pivots with and supports the drive leg and as the trim actuator trims the drive leg about the trim axis.

A mounting structure for mounting a propulsion unit to a hull of a floating structure includes a first mounting surface and a sealed portion provided on the first mounting surface for sealing the propulsion unit to the hull. The first mounting surface is further provided with a pivot point provided at an edge or in the vicinity of an edge of the first mounting surface and outside the sealed portion, and at least two first protrusions spaced from each other on the first mounting surface. Each of the first protrusions includes a surface at least on a side of the first protrusion facing away from the pivot point, which surface is formed at least in a direction perpendicular to the first mounting surface in a manner dependent of a distance between the pivot point and the surface in such a manner that the first protrusion provided in a cylindrical cavity formed in a counterpart is configured to guide a mutual tilting movement of the cylindrical cavity and the first protrusion, when the mounting structure and, thus, the first protrusions are tilted with respect to the cylindrical cavities about the pivot point.
