Abstract
A number of embodiments of warning devices for watercraft provided with a plurality of marine propulsion engines for providing an arrangement for avoiding course deviations in the event of an abnormal running condition of one of the engines which tends to cause a course deviation. In one embodiment, the course correction is provided by slowing of the normally running engine in the event of slowing of the abnormally running engine. In other embodiments, the course deviation is prevented by a steering device. In one embodiment, the steering device comprises means for steering of the normally running engine and in another embodiment, the steering device comprises a trim tab.
Claims23
In a marine propulsion device for a watercraft having a first engine driving first propulsion means, a second engine driving a second propulsion means, sensing means for sensing an abnormal condition of either of said engines independently of the other engine condition tending to cause a substantial deviation in the course of said watercraft, and means responsive to the sensing of such an abnormal condition for initiating the operation of means for preventing course deviations due to said abnormal condition.
In a marine propulsion device for a watercraft having a first engine driving first propulsion means, a second engine driving second propulsion means, first sensing means for sensing an abnormal condition of said first engine independently of the condition of said second engine tending to cause a substantial deviation in the course of said watercraft, first warning means activated by said first sensing means for warning an operator of the abnormal condition, second sensing means for sensing an abnormal condition of said second engine independently of the condition of said first engine tending to cause a substantial deviation in the course of said watercraft, second warning means activated by said second sensing means, and means for activating both of said warning means upon the sensing of an abnormal condition by either of said sensing means.
