A method of steering a planning V-bottomed boat with double individually steerable outboard drive units with underwater housings (), which extend down from the bottom () of the boat. When running at planning speed straight ahead, the underwater housings are set with 'toe-in', i.e. inclined towards each other with opposite angles (alpha) of equal magnitude relative to the boat centre line (b). When turning, the inner drive unit is set with a greater steering angle than the outer drive unit.

Method of steering a boat with double outboard drives and boat having double outboard drives

An apparatus for shifting a transmission coupled to an engine including a controller for shifting the transmission between operating modes, a control lever for switching the transmission, and an actuator for actuating the control lever in response to shifting of the controller. The apparatus includes a longitudinal tube connected to the controller, a cylindrical slide connected to the actuator for actuating the control lever in response to shifting of the controller, the longitudinal tube being coaxial with the cylindrical slide, a detector for detecting relative displacement between the longitudinal tube and the cylindrical slide, and a spring acting between the longitudinal tube and the cylindrical slide to prevent relative displacement between them until a force acting on one of them exceeds the spring force of the spring.
