Patent number: 10507898Abstract: An electromechanical lockout device for a remote control on a marine vessel includes an electric actuator and a locking pin having an engagement end and a second end. The locking pin is arranged with respect to a control lever such that the locking pin is positionable in a locked position, where the engagement end of the locking pin prevents rotation of the control lever into a reverse position, and in a retracted position, where the engagement end of the locking pin allows rotation of the control lever into the reverse position. A method of controlling lockout for a remote control includes sensing a position of a control lever, calculating a rate of change of the position, and engaging a lockout to prevent a gear system from shifting into reverse gear if the rate of change exceeds a threshold rate of change.Type: GrantFiled: October 25, 2017Date of Patent: December 17, 2019Assignee: Brunswick CorporationInventors: David J. Belter, Jeffrey J. Broman, Eric S. Mueller

Patent number: 9909545Abstract: An outboard motor includes an internal combustion engine powering the outboard motor and a cowl covering the engine and having a vent allowing air under the cowl. A throttle body meters flow of the air into the engine and an intake structure downstream of the throttle body delivers the metered airflow to one or more combustion chambers in a cylinder block of the engine. A sound enhancement assembly in acoustic communication with the intake structure collects sounds emitted by the engine. The sound enhancement assembly is configured to amplify a subset of the collected sounds that have frequencies within a desired frequency range. A method for modifying sounds produced by an air intake system of an internal combustion engine powering an outboard motor is also disclosed. The method includes positioning a sound enhancement assembly in acoustic communication with an air intake passageway located downstream of the engine's throttle body.Type: GrantFiled: July 26, 2016Date of Patent: March 6, 2018Assignee: Brunswick CorporationInventors: Andrew S. Waisanen, Jeffrey C. Etapa, Wayne M. Jaszewski, Jeffrey J. Broman, Brian J. Fregonese

Patent number: 9903251Abstract: An internal combustion engine for an outboard motor comprises a cylinder block having first and second banks of cylinders that extend transversely with respect to each other in a V-shape so as to define a valley there between. An exhaust manifold conveys exhaust gas from the internal combustion engine and is at least partially disposed in the valley. A supporting mechanism supports the exhaust conduit with respect to the internal combustion engine. The supporting mechanism is configured to allow the exhaust conduit to move with respect to the internal combustion engine in 360 degrees in a plane defined by the lateral and transverse axes, and laterally towards and away from the internal combustion engine, thereby facilitating assembly of the exhaust manifold and the internal combustion engine despite positional tolerance differences there between.Type: GrantFiled: November 29, 2016Date of Patent: February 27, 2018Assignee: Brunswick CorporationInventors: David J. Belter, Jeffrey J. Broman, Mark J. Glodowski, Douglas D. Reichardt, Timothy S. Reid

Publication number: 20160363061Abstract: Systems and methods are for controlling internal combustion engines having a plurality of piston-cylinders that cause rotation of a crankshaft. A crankshaft sensor is configured to sense rotational speed of the crankshaft. A controller is configured to calculate an acceleration for each piston-cylinder based upon the rotational speed of the crankshaft and then balance the accelerations of the respective piston-cylinders by modifying a combustion input to one or more of the piston-cylinders in order to reduce engine vibration.Type: ApplicationFiled: September 17, 2014Publication date: December 15, 2016Applicant: BRUNSWICK CORPORATIONInventors: Andrew S.

Patent number: 8038493Abstract: A catalyzed exhaust system for an outboard motor engine rotates its catalyst device in a catalyst housing above an adapter plate which supports the engine and separates it from the driveshaft housing. The exhaust gas is directed initially in an upwardly direction and then is turned downwardly to provide space for location and easy access to the catalyst device. A coolant, such as water drawn from a body of water, is reversed in direction of flow several times in order to advantageously fill certain cooling channels in an upward direction. In addition, various coolant channels are vented to remove potential pockets of air in their upper regions.Type: GrantFiled: April 14, 2009Date of Patent: October 18, 2011Assignee: Brunswick CorporationInventors: Jeffrey J.

Patent number: 7942138Abstract: An outboard motor is provided with an exhaust gas recirculation (EGR) system that provides a heat exchanger which reduces the temperature of the exhaust gas prior to introducing the exhaust gas to the cylinders of the engine. The heat exchanger can be integral to the engine, particularly the cylinder head of the engine, or it can be disposed outside the structure of the engine. When disposed outside the structure of the engine, the heat exchanger can comprise a tubular structure that causes exhaust gas and water, from the body of water, to flow in thermal communication with each other. Alternatively, the heat exchanger which is disposed outside the structure of the engine can use a cavity within the driveshaft housing as a heat exchanger with water being sprayed into the stream of exhaust gas as it passes from the engine to the cavity.Type: GrantFiled: March 24, 2008Date of Patent: May 17, 2011Assignee: Brunswick CorporationInventors: David J.

Patent number: 7299783Abstract: A marine propulsion device is provided with an air control system that draws air from the region under the cowl of the outboard motor and induces a flow of air out of the region. The air is caused to flow through a second opening formed in the cowl. As a result, air drawn into the cowl through a first opening can flow either into the engine through its throttle body mechanism or out of the space under the cowl, as induced by the operation of the fan.Type: GrantFiled: February 22, 2006Date of Patent: November 27, 2007Assignee: Brunswick CorporationInventors: Jeffrey J.

Patent number: 7021262Abstract: An air intake system for an outboard motor provides parallel air flow paths between an opening formed in a cowl of the outboard motor and an air intake manifold of an engine under the cowl. A first air path flows in a relatively direct path between the opening in the cowl and the first inlet of a plenum chamber. A second air flow flows in a less direct path from the opening in the cowl to a second inlet of the plenum chamber. The second air flow is used to remove heat from a preselected component, such as an alternator, before it rejoins the first air flow within the cavity of the plenum chamber and is directed, in combination with the first air flow, through an intake air conduit connected to an outlet of the plenum chamber and to an air intake manifold of the engine.Type: GrantFiled: September 23, 2004Date of Patent: April 4, 2006Assignee: Brunswick CorporationInventors: David J.
