  • Patent number: 8808045
    Abstract: A method for controlling the exit of exhaust gases from an engine which is used to power an underwater propeller drive arranged at the hull bottom of a boat is provided. According to the method exhaust gases are allowed to flow from the engine through an exhaust channel and exit through a first underwater exhaust outlet in the underwater propeller drive. According to the method, if the engine is running and the transmission of the propeller drive is in neutral position, a second underwater exhaust outlet is opened for letting exhaust gases in the exhaust channel exit in a position closer to the hull bottom of the boat than the first underwater exhaust outlet.

  • Patent number: 8444391
    Abstract: A propeller drive for boats features a transition cone between the gearbox housing and the propeller hub(s). The propeller hub (that is closest to the gearbox housing) is smaller in cross-sectional dimension than the gearbox housing. The dimension of the front end of the transition cone corresponds to the cross-sectional dimension of the gearbox housing, and the dimension of the rear end of the transition cone corresponds to the cross-section dimension of the (closest) propeller hub. The transition cone has a bulging shoulder between the front and rear ends, the largest peripheral cross-sectional dimension of which is greater than the cross-sectional dimension of the front of the transition cone.
