ABSTRACT:
A marine outboard engine has a section of its cooling water suction passage defined by an annular groove formed in the periphery of a bearing housing which accommodates the bearing of the propeller shaft. This allows the suction passage to be connencted to a water intake formed on a lower section of the torpedo of the engine without the need to increase the size of the torpedo. This results in a smaller, lighter configuration for the lower case while still allowing the engine to be operated in a super high mount operating mode which is appropriate for use with a super cavitation propeller, due to the low position of the cooling water intake.
