Stern operatively mounted universal sonic transducer for boat

Abstract

A stern operatively mounted universal transducer for boat includes a mounting device, having upper and lower brackets, for securement to the boat, preferably its transom, the upper and lower brackets secure a drive cylinder, which when operative, lowers a drive rod for shifting a sonic transducer upwardly above the water, or downwardly into the water to scope the surrounding underwater typography. A pair of guide rods shiftably extend through the upper and lower brackets, and at their upper ends, secure to a motor and gear housing, the guide rods at their lower ends secure to a base plate. A transducer shaft extends into the motor housing which provides for its pivoting, and at its lower end, extends downwardly through the base plate, and secures a transducer mounting plate, to which the transducer is affixed, in preparation for its usage. Electrical, pneumatic, or hydraulic pressure can be used to pivot the transducer shaft, and to raise and lower the base plate that connects with the drive shaft, the latter when operative, raises or lowers the entire transducer assembly into and out of the water, during application.
