A drivetrain for a marine propulsion device includes an engine driving a crankshaft in a first direction, and a driveshaft connected in torque-transmitting relationship with the crankshaft and supported for rotation about a driveshaft axis. The drivetrain further includes a propeller shaft rotatable about a propeller shaft axis. A gearset and a selector clutch are configured to couple the propeller shaft and the driveshaft to each other in torque-transmitting relationship. A one-way clutch is disposed along the drivetrain upstream of the gearset. The one-way clutch prevents rotation of the crankshaft in a second, opposite direction so as to prevent ingestion of water by the engine via an engine exhaust system.

Methods and apparatus to power an exercise machine are disclosed herein. An example exercise machine includes a generator to convert movement of a moveable part of the exercise machine into electric power. The example exercise machine includes a generator power receiver to measure the power output by the generator, and to calculate a rotations per minute of the moveable part. A mode controller is to calculate a power supply duty cycle based on the power output by the generator, the rotations per minute of the moveable part, and a user selected wattage. A power output controller is to control power provided to a console of the exercise machine based on the power supply duty cycle.

A method for creating a parametric planing hull model is disclosed. In one embodiment, dimensions of a plurality of hull sections, including two non-adjacent hull sections, are received from a user. Dimensions of at least one hull section between the two non-adjacent hull sections are interpolated. Curves of the hull are generated based on the dimensions of the plurality of hull sections received from the user and the interpolated dimensions of the at least one hull section between the two non-adjacent hull sections. Surfaces of the hull are created based on the generated curves, and a planing hull model is generated from the created surfaces and is displayed.

A hull form design which incorporates bi-lateral semi-sponsons disposed on either side of a non-stepped V-shaped center hull section. The semi-sponsons extend the entire length of the hull form and comprise protrusions extending away from the center section. The semi-sponsons are delimited by longitudinal steps extending below the hull bottom an equal distance from the centerline on opposite sides of the hull. This design is a hybrid of conventional V hulls and catamarans and improves the roll and turn initiation time of convention monohull designs.


Contact pressure sensing apparatus for use with exercise equipment sensors are described. An example apparatus includes a sensor to detect a physiological condition of a user of an exercise device through physical contact with the user and a pressure sensor to detect a contact pressure applied by the user to the sensor.


A system and method control a trim device that positions a trimmable marine apparatus with respect to a marine vessel. A trim system is operated in an automatic mode, in which a controller sends signals to actuate the trim device automatically as a function of vessel or engine speed, or a manual mode, in which the controller sends signals to actuate the trim device in response to commands from an operator input device. An operating speed of the propulsion system is determined. When the operating speed has crossed a given operating speed threshold, the trim system is subsequently operated in the automatic or manual mode depending on whether the operating speed increased or decreased as it crossed the operating speed threshold and whether the trim system was operating in the automatic or manual mode as the operating speed crossed the operating speed threshold.


A trim control system automatically controls trim angle of a marine propulsion device with respect to a vessel. A memory stores trim base profiles, each defining a unique relationship between vessel speed and trim angle. An input device allows selection of a base profile to specify an aggressiveness of trim angle versus vessel speed, and then optionally to further refine the aggressiveness. A controller then determines a setpoint trim angle based on a measured vessel speed. If the user has not chosen to refine the aggressiveness, the controller determines the setpoint trim angle from the selected base profile. However, if the user has chosen to refine the aggressiveness, the controller determines the setpoint trim angle from a trim sub-profile, which defines a variant of the relationship between vessel speed and trim angle defined by the selected base profile. The control system positions the propulsion device at the setpoint trim angle.


An exercise assembly comprises a frame and elongated foot pedal members that are each movable along user-defined paths of differing dimensions. Each foot pedal member has a front portion and a rear portion. Footpads are disposed on the rear portion of one of the pair of foot pedal members. Elongated coupler arms have a lower portion and an upper portion that is pivotally connected to the frame. Crank members have a first portion that is pivotally connected to the front portion of one of the pair of foot pedal members and have a second portion that is pivotally connected to the lower portion of one of the pair of coupler arms, such that each crank member is rotatable in a circular path. Elongated rocker arms have a lower portion that is pivotally connected to one of the pair of foot pedal members in between the foot pad and the crank member and have an upper portion that is pivotally connected to the frame.

A marine transmission located within drive housing includes a torque transmitting year set and a clutch mechanism. The torque transmitting gear set includes top and bottom bevel gears and opposing side idler bevel gears mounted to a pinion shaft. The pinion shaft is mounted on a carrier and the clutch mechanism engages the carrier to rotate with the input shaft to drive the output shaft in the forward direction and engages the carrier to a reaction plate fixed to the drive housing to drive the output shaft in the reverse direction.

Fuel cap apparatus for use with fuel venting systems are described. An example fuel cap apparatus includes a body having a central cavity and a flange. A membrane is coupled to the body to form a passageway therethrough and coated with a material to substantially prevent the flow of liquid and permit the flow of gas through the passageway.
