2-37. Bilge Pumps
Operation of the bilge pumps depends on operation of engines. Pumping can be accomplished with any one of all three bilge pumps,
if at least one port and one starboard engine is operating, by moving the control lever of the corresponding pump in NORMAL
OPERATION position. If one or both engines on one side only are operating, the operator can actuate the port or starboard bilge
pump on the dead engine side by moving the control lever in EMERGENCY position on the operating engine side.
2-38. Cargo Well Pumps
Operation of the cargo well pumps depends on operation of the engines. With engines operating on both sides, pumping can be
accomplished BY pulling back on the control lever for NORMAL operation. If the engines on one side only are operating, the operator
can acutate the cargo well pump on the dead engine side by pushing the control lever forward, into EMERGENCY position, on the
operating engine side. If the LARC is listing to one side with engines operating on both sides, and it becomes necessary to operate
the cargo well pumps and the bilge pumps together on one side only, the operator can place the cargo well pump control on high side
of the LARC in emergency position and operate the bilge pump on low side of the LARC in the normal control position.
2-39. Propellers
Propellers should be engaged only when operating in water. Land drive transmission should be in neutral except when entering and
leaving the water.
a. To engage the propellers, place the marine gear controlvalves (4, sheet 1, fig. 2-1) in forward position for forward operation
or in reverse
