Abstract
A drive apparatus ( ) for a boat having a planing hull ( ) including a notch ( ). An engine ( ) and a transmission ( ) are mounted within the hull. A propeller shaft ( ) is connected to the transmission with a universal joint ( ) and extends rearwardly therefrom into the notch. The propeller shaft passes through a shaft support ( ), and a propeller ( ) is affixed to the propeller shaft behind the shaft support. The shaft support depends from a strut ( ), which is mounted on the underside of a pivot arm ( ). A trim drive ( ) is mounted within the hull and above the notch and the pivot arm. A linearly extendable trim drive shaft ( ) extends between the trim drive and the pivot arm and, when the trim drive is actuated, pivots the pivot arm, and thus the propeller, selectively upwardly and downwardly to adjust trim for maximum drive efficiency under various boat load distribution, water surface and wind conditions.
