The following is an excerpt from this manual:

Reverse and Reduction Gear – The reverse gear is self-contained and is independent of the engine oil pressure system. Pressured oil for the operation of the reverse gear is provided by an oil pump mounted inside
of the reverse gear. The oil pump is driven continuously by the engine.
The pressurized oil is delivered from the oil pump to the control valve and then to the forward or reverse piston, depending upon the
control valve setting.

A relief valve maintains the oil at a constant pressure. The pressurized oil will be approximately 125 psi at engine speeds over 1000 rpm. The pressure will be as low as 60 psi at idle speeds. Due to variances in the relief valves, pressures slightly above or below these valves may be encountered.

When shifting the control valve to the forward position, the pressured oil is directed to the multiple disc clutch piston. This clamps the multiple disc clutch, which turns the propeller shaft in the right hand direction or in the same direction as the engine is turning. When shifting the control valve to the reverse position, the pressured oil is directed to the reverse piston, which clamps the planetary reverse gear train, which turns the propeller shaft in the left hand direction or in the opposite direction as the engine is turning.

When the control valve is in the neutral position, the pressured oil is stopped from entering either the multiple disc clutch piston or the reverse band piston.
