A stern drive for a marine vessel having a transom. The stern drive has a drive assembly comprising a drive unit configured to generate a thrust force in water and a powerhead configured to power the drive unit, and a transom bracket assembly configured to support the drive unit outside of the transom and further configured to support the powerhead inside of the transom, wherein the transom bracket assembly is configured to vibrationally isolate the drive unit and powerhead relative to the transom.

A system for antifouling of a marine drive having a frame coupled to a propulsor housing may include a vibration dampening joint which couples the propulsor housing to the frame or an extension thereof. The vibration dampening joint may include an isolator connector assembly having an elastomeric member which is clamped between the propulsor housing and the frame or the extension thereof such that all vibrations emanating from the propulsor housing pass through the elastomeric member. A power source for providing electricity may be supported on the frame. An electric circuit may have a first end coupled to the power source and an opposite, second end coupled to the propulsor housing. The electric circuit may be configured to convey electricity from the power source to the propulsor housing and thus prevent fouling thereof, wherein the electric circuit extends through the vibration dampening joint.

Provided is a pod propulsion system including first and second counter rotating propellers for propelling a marine vessel first and second propeller modules, each including an electric motor having a driving-end configured to rotate the first and second propellers, respectively. Also included are first and second gondolas, each (i) for housing a respective one of the first and second electric motors and (ii) including a boltable interface formed along a lengthwise direction of an extremity of the gondola. A strut (i) connects the first and second gondolas to a hull of the marine vessel (ii) including first and second boltable interfaces. Each of the boltable interfaces of the strut is configured to form a bolted joint interface with a corresponding one of boltable interfaces of the first and second gondolas.

A marine vessel includes a hull assembly, and the hull assembly includes a deck assembly, a first battery assembly, a second battery assembly and an electric motor assembly. The deck assembly is contained within the hull assembly. The first battery assembly is located completely under the deck assembly. The second battery assembly is located completely under the deck assembly and is physically separate from the first battery assembly. The electric motor assembly receives electric power from the first battery assembly and the second battery assembly to propel the hull assembly through water during operation.

A marine drive is for propelling a marine vessel in a body of water. The marine drive has a supporting frame configured to support the marine drive with respect to the marine vessel; an extension leg depending on the supporting frame; a motor housing depending on the extension leg, the motor housing for containing an electric motor; and a vibration isolating joint which couples the extension leg to the motor housing. The vibration isolating joint has an isolating connector assembly having an elastomeric member which is clamped between the extension leg and motor housing and configured to limit transfer of vibrations from the motor housing to the extension leg, and a compression limiter which prevents over clamping of the elastomeric member during assembly of the extension leg and the motor housing.

An outboard motor includes an outboard motor main body and a mount assembly to mount the outboard motor main body to a hull. The mount assembly includes a clamp bracket to be fixed to the hull, a swivel bracket to support the outboard motor main body, and a hydraulic cylinder. The swivel bracket is coupled to the clamp bracket through a tilt shaft and turnable around the tilt shaft. The hydraulic cylinder is located between the clamp bracket and the swivel bracket and is able to turn the swivel bracket around the tilt shaft with respect to the clamp bracket. The outboard motor includes a gas damper to damp an external force that acts in a telescopic direction of the hydraulic cylinder.

A unitary hermetically sealed device is disclosed for providing self-contained electric propulsion drive power to a motor boat or sailboat, where the entire propulsion system is contained in a separable pressurized hermetic enclosure attached to the underside of the vessel and also acts as a keel of the vessel, and which simplifies production, provides improved safety from high voltages, and prevents drive system maintenance or repair when the vessel is located in the water. The rigid hermetically sealed device functions as a skid-plate to avoid damage to the softer typically fiberglass hull when running the vessel aground or when running up onto or off of the beach or onto or off a trailer.

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.
