ABSTRACT:
A recess flow plate mounted to a boat hull to substantially cover a through-hull mounting recess located on the bottom of a boat hull is disclosed. The through hull mounting recess has an upstanding front wall which is adapted to receive the propeller shaft and a tapered top wall which extends rearwardly from the upstanding front wall. The flow plate is removably secured over the through-hull recess to maintain the laminar flow of water across the bottom of the boat hull.
