This is the 24V DC-powered hydraulic pump, good for a ~32 second cant time (full trip from all the way out on one side to all the way out on the other) without engine running. The (modified for this boat) reservoir has the pump itself set up inside the reservoir, the black column on the left is the DC motor. Sight glass on the right.
This is the engine-driven ('clutched') pump, good for a full cant time of ~15s with engine running.
