An improved boat and drive assembly intended for a boat used in a primary shallow water environment has a hull with an integrated closed internal engine heat exchanger and a drive assembly that includes a ring-within-a-ring steering mechanism and an obstacle resistant shoe plate. Stabilizer fins positioned above the shoe plate at a position forward of the spinning propeller allow air and water to exit from the rear of the stabilizer fins away from the spinning propeller. The heat exchanger assembly may include an axillary cooling tank and open heat dissipation system having a raw water reservoir continuously filled with raw water drawn directly from the waterway on which the boat is propelled to enhance the cooling capacity of the integrated internal engine heat exchanger.
