  • Patent number: 7685899
    Abstract: A two speed transmission including an input shaft; a lay shaft spaced from the input shaft; a first gear train connecting the input shaft to the lay shaft; a second gear train connecting the lay shaft to an output shaft, the gear train including a one way clutch or similar; and a clutch for engaging the input shaft with the output shaft. When the clutch is disengaged, power is transmitted from the input shaft via the gear trains and the lay shaft via the one way clutch to the output shaft which typically provides first or low gear for use in low speed maneuvering or where greater torque is required. With the clutch engaged, power may be transmitted from the input shaft directly to the output shaft to provide a second gear for when the watercraft is cruising.

The transmission is arranged such that when the output shaft is disengaged from the input shaft power is transmitted to the output shaft via the first and second gear trains and the lay shaft. When the clutch is disengaged, power is transmitted from the input shaft via the gear trains and the lay shaft via the one way clutch to the output shaft which typically provides first or low gear for use in low speed maneuvering or where greater torque is required. With the clutch engaged, power may be transmitted from the input shaft directly to the output shaft to provide a second gear for when the watercraft is cruising.

  • Publication number: 20050011556
    Abstract: A position sensor senses the position of an article that moves over a short predetermined path. The position sensor is contained in a housing which is mounted in a fixed location adjacent the article and has an internal cavity in which a valve follower travels guided by the walls of the cavity to describe a predetermined path in the axial direction. The valve follower is operatively coupled with the article and carries a sensed magnetic element. A sensor is mounted in the housing adjacent the path of the valve follower, such that the sensed element moves laterally under the sensor and the sensor generates a signal indicative of its position.
