The Edward M. Cotter has four Caterpillar D-397 V-type 12 cylinder engines having a rating of 400 HP for continuous duty, with 450 HP for a period of two hours. (Another source quotes them at 475 HP at 1,500 rpm.)

Two of the engines are forward and two are aft.

The forward engines are used for pumping and are paired with DeLavel pumps that draw directly from the river or lake from intakes below the waterline. The four pumps were made by Dean Hill Pump Company of Indianapolis and deliver 3,750 gallons per minute at a discharge of 160 lbs.

Mainly used for propulsion, the aft engines are also paired to DeLavel pumps. They are employed for pumping to bring the boat up to its full 15,000 gpm capacity.

Each engine has an air-operated Falk marine clutch and transmission.

The engine room is surrounded by the 12-inch belt line that feeds water to the monitors and manifolds. The belt line is connected to the pumps by pipes.

The propellers are four blade, 60" diameter cast steel made by Kahlenberg Brothers Company of Two Rivers, Wisconsin.
