ABSTRACT:
A hydraulic pump is serially connected in a closed loop hydraulic circuit provided with a control valve for controlling the flow of hydraulic fluid through the circuit and the hydraulic motor has mounting structure operatively associated therewith for releasably supporting the hydraulic motor from the lower end gear housing of a marine drive assembly such as that used on outboard motors and inboard/outboard drive assemblies. The fluid motor includes a rotary power input shaft and is supported by the support structure with its input shaft axially aligned with the rear end of the propeller shaft of the lower end gear housing. Coupling structure is utilized to releasably drivingly couple the propeller shaft to the rotary input shaft of the hydraulic motor and the latter, in conjunction with the control valve equipped closed loop fluid circuit, may be used to apply an adjustable load on the marine drive assembly propeller shaft and in this manner the associated outboard motor for inboard/outboard drive system may be operated at any throttle setting and operating speed in order to simulate actual on water operating conditions, the hydraulic motor and associated marine drive unit being receivable within a conventional test tank or a flushing unit attachment being utilized in conjunction with the marine drive assembly in order to provide sufficient cooling water for the motor of the marine drive assembly.
