ABSTRACT:
A marine drive (10) has two counter-rotating surface operating propellers (12 and 14). A planing plate (230) extends rearwardly from the drive housing (20) above the propellers (12 and 14) and pushes down on the surface of the water during initial boat acceleration to in turn lower the bow and aid in getting the boat up on plane. Right and left inclined splash plates (240 and 242) along the sides of the housing (20) extend from the torpedo portion (188) rearwardly and upwardly at an incline and meet the planing plate (230).
