An improved trimming arrangement is disclosed which is particularly suited for use with a craft having planing hull with a marine drive. In one embodiment, the trimming arrangement includes a submerged trim hydrofoil which is affixed to the drive housing of the drive system beneath the screw propeller drive shaft. So that the efficiency of the planing hull and drive system are improved at hull-planing speeds, the trim hydrofoil is positioned to create a downward force component of the stern of the planing hull during forward movement through the water. T...
An improved marine drive system for a planing hull comprising: drive housing means adjustably mounted on the stern of said planing hull by a ball and socket mount extending aft of the stern transom, steering means for pivoting said housing means laterally of said hull about said mount, trimming means for pivoting said housing means vertically of said hull about said mount, a propeller drive shaft rotably carried by said housing means and having a screw propeller adapted to operate in a partially submerged condition for propelling said planing hull throug...
