| 20090130926 | Vibration isolation system for marine vessels - A marine propulsion support system incorporates a vibration isolation structure which comprises a plurality of elastomeric support components, or mounts. The vibration isolation structure is disposed between a marine vessel and a propulsion drive mounting transom to which a marine propulsion component, such as an outboard motor, can be attached. Support of the propulsion drive mounting transom by the marine vessel extends through the vibration isolation structure so that elastomeric portions of the elastomeric support components can damp any vibration emanating from a marine propulsion device, such as an outboard motor, and a deck of a pontoon boat or other marine vessel. | 05-21-2009 |
| 20090191773 | Method and apparatus for absorbing, dampening and/or reducing sounds and vibrations created by the use of an electric trolling motor; which at the same time protects the trolling motor against damage by dampening force and/or sounds from external trauma - A covering created to be attached to an electric trolling motor propulsion unit and/or shaft in order to absorb the sounds and vibrations created during the use of the trolling motor. The Invention is created from a material, such as rubber or synthetic rubber or of another material with sound dampening qualities, which dampens and/or absorbs sound, force and/or vibrations. The preferred embodiment of the Invention is a customized rubber or synthetic rubber covering that is applied flush to a portion of a trolling motor propulsion unit and/or shaft thereby reducing the vibrations distributed into the water into which the trolling motor is submerged and thus minimizing aquatic disturbance. Additional purposes of this method and apparatus is to both protect the trolling motor from damage caused by external trauma or blows and to dampen sounds and vibrations created from such external trauma. | 07-30-2009 |
| 20100035489 | MARINE PROPULSION AND CONSTRUCTIONAL DETAILS THEREOF - A marine drive system mounted in the hull of a marine craft, the marine drive system comprising an engine connected to a gearbox by means of a drive shaft ( | 02-11-2010 |
| 20100055999 | Vibration damper for an electric trolling motor - The invention is an accessory vibration damper that is applied over the diameter of any submersible electric motor housing of any modern electric trolling motor. Vibration damper is molded as a single unitary piece of an elastomeric compound that can have plural appendages placed perpependicular to the rotating armature of motor. Said appendages counteract the frequency range of vibrations produced while electric trolling motor is under propulsion. | 03-04-2010 |
| 20100068952 | OUTBOARD MOTOR - An outboard motor that is capable of reducing a trolling noise includes an engine which has a crank shaft extending in an up-down direction; a drive shaft extending downward from the crank shaft and including a torsion bar spring; a propeller shaft; a propeller provided in the propeller shaft; a forward/backward switching mechanism arranged to connect the drive shaft and the propeller shaft with each other; and a vibration damper which includes a first cylindrical body and a second cylindrical body which are penetrated by the torsion bar spring. The first cylindrical body and the second cylindrical body are coaxial with each other. The first cylindrical body has its upper end portion connected with an upper end portion of the torsion bar spring whereas the second cylindrical body has its lower end portion connected with a lower end portion of the torsion bar spring. A viscous fluid is filled between the first cylindrical body and the second cylindrical body. | 03-18-2010 |
| 20100297896 | MARINE PROPULSION AND CONSTRUCTIONAL DETAILS THEREOF - A mount for supporting part of a marine drive system to a marine hull, the mount comprising a rigid outer housing ( | 11-25-2010 |
| 20120289104 | OUTBOARD MOTOR - An outboard motor includes an engine, a flywheel, a twisting member, and a damper. The engine includes a crankshaft that is rotatable around a crank axis extending in the up-down direction and includes an upper end portion disposed along the crank axis. The flywheel includes a joint portion that is disposed above the upper end portion of the crankshaft and joined to the upper end portion. The twisting member is disposed along the crank axis above the upper end portion of the crankshaft, and is arranged to rotate around the crank axis together with the crankshaft. The damper is disposed above the flywheel at a distance from the flywheel, and joined to the twisting member. | 11-15-2012 |
| 20150298784 | MOUNT DEVICE FOR OUTBOARD MOTOR - An outboard motor having an outboard motor body generating a thrust by rotating a propeller that is driven by an engine mounted to the outboard motor and an attachment device for attaching the outboard motor body to a hull. The outboard motor includes a mount device having an upper mount and a lower mount arranged between the outboard motor body and the attachment device for attaching the outboard motor body to the hull and supports an upper portion and a lower portion of the outboard motor body, respectively. The mount device also includes an anti-vibration unit and a displacement restriction unit. The lateral displacement restricting mount section and a member opposing the lateral displacement restricting mount section abut against each other with the abutment surfaces inclined with respect to a longitudinal direction of the outboard motor body. | 10-22-2015 |
