In carrying out a crash-go-astern operation for switching operating means ( ) of a hydraulic clutch mechanism ( ) provided to a marine reduction and reverse gear ( ) from a forward setting (F) to a reverse setting in a stroke so as to abruptly stop in traveling ahead, a propeller speed (PN) is detected in neutral (N) halfway through the switching and initial fitting pressure (Po) of a reverse driving clutch ( ) is calculated by using a map of the initial fitting pressure (Po) of reverse clutch pressure (Pr) formed according to the propeller speed based on a ship load (SL) in advance before switching to the reverse setting (R), the reverse driving clutch ( ) is set at the calculated initial fitting pressure (Po) when the operating means is switched to the reverse setting (R), and then the reverse clutch pressure (Pr) is increased to a maximum value (Pm) as an engine speed (EN) increases.
