Marine gear and a method for preventing a drop in motor speed when engaging a multi-plate clutch

A marine reversing gear comprising:

• a) a hydraulic control assembly including at least one pressure control line;
• b) a plurality of multi-plate clutches coupled to said at least one pressure control line;
• c) a control means coupled to said at least one pressure control line and in hydraulic communication with said multi-plate clutches comprising:
• i) at least one proportional valve;
• ii) at least one pilot operated pressure-control valve, which can be operated by said at last one proportional valve to release a return flow of oil, and wherein said pressure control valve is coupled to said at least one pressure control line;
• d) at least one sensor coupled to said at least one pressure control line for detecting at least one parameter;
• and
• e) a control unit in communication with said sensor, for receiving signals from said sensor and relaying said signals to said control means to control a hydraulic pressure in said hydraulic control assembly to prevent a drop in speed when a motor engages at least one of said plurality of multi-plate clutches.
