Patent number: 10370070Abstract: A combination trim tab and interceptor comprises a housing and a trim tab pivotably coupled to the housing. An interceptor blade is reciprocatingly received by the housing. A cam is coupled to the trim tab and the interceptor blade. The cam is coupled to the trim tab by a link which applies a rotary force when the trim tab pivots relative to the housing. The cam is coupled to the interceptor blade such that the interceptor blade functions as a cam follower. An actuator actuates the trim tab to pivot relative to the housing. Pivoting of the trim tab results in the cam applying a force to the interceptor blade, causing the interceptor blade to reciprocate relative to the housing. The cam may be configured so a stroke of the interceptor blade and a stroke of the actuator are non-linear. The actuator may be an electromechanical linear actuator.Type: GrantFiled: May 17, 2018Date of Patent: August 6, 2019Assignee: Marine Canada Acquisition Inc.Inventors: Eric B. Fetchko, Davor Baros, Art Ferguson

Patent number: 10202179Abstract: There is provided a mounting assembly for a marine vessel having a pair of stern-mounted propulsion units. The assembly includes a pair of angle-setting members which forwardly angle the propulsion units towards a bow of the marine vessel when each propulsion unit is at the center of its total steering range. Each propulsion unit has a line of action of its propulsion force. The lines of action of the propulsion units intersect each other between a center of rotation of the marine vessel and a stern of the marine vessel when the propulsion units are steered forwardly towards each other.Type: GrantFiled: May 14, 2014Date of Patent: February 12, 2019Assignee: Marine Canada Acquisition Inc.Inventors: Ray Tat Lung Wong, Neal Wesley Denis Wood

Publication number: 20190009875Abstract: A steering apparatus comprises a rotatable steering shaft and a sensor which senses angular movement of the steering shaft. An electromagnetic actuator actuates a stop mechanism to releasable engage the steering shaft. There is a microcontroller which causes the electromagnetic actuator to actuate the stop mechanism to fully engage the steering shaft and prevent rotation of the steering shaft in a first rotational direction, which corresponds to movement towards the hardstop position, while allowing rotational play between the steering shaft and the stop mechanism in a second direction, which corresponds to rotational movement away from the hardstop position, when the sensor senses that the steering shaft has reached a hardstop position. A driver applies a reverse polarity pulse to the electromagnetic actuator when the stop mechanism is fully engaged and the steering shaft is rotated, as permitted by the rotational play, in the second rotational direction.Type: ApplicationFiled: March 5, 2018Publication date: January 10, 2019Applicant: MARINE CANADA ACQUISITION, INC.Inventors: CHAN ANSON, CLARKE DOUGLAS, HIGGS DAVID
