ABSTRACT:
A marine transmission mounting system for marine engine and drive that are mounted in a mid-travel position to joists in the hull space between a hull and a floor of the boat. Such a system is typically used on a competition water-ski boat where the engine, transmission, and propeller shaft are mounted in-line at a downward angle with respect to a floor of the boat such that the propeller shaft passes through the hull of the boat in front of the transom. The transmission mounting system includes a transmission mounting bracket having reinforcement webs located above the span of the bracket so that smaller reinforcement webs can be located below the span of the bracket. With such a bracket, there is sufficient room underneath the bracket so that an engine exhaust tube can pass under the bracket. This allows overall engine and exhaust system space requirements above the floor of the boat to be reduced.
