(8) Jacket water pump
(9) Cylinder block Coolant is pulled from the heat exchanger (2) into the jacket water pump (8) by impeller action. The jacket water pump is located on the front left side of the engine. The jacket water pump is gear-driven.The coolant is pumped through the cylinder block (9). The coolant is distributed around each cylinder. At each cylinder, coolant enters the cylinder head (5). The coolant then enters the water outlet manifold. The coolant then enters the water cooled exhaust manifold (4). The coolant then flows to the water temperature regulator (3). With the water temperature regulator in the closed position, the coolant bypasses the heat exchanger (2) and flows back to the jacket water pump (8) for recirculation. With the water temperature regulator in the open position, the coolant is directed through the heat exchanger (2) and back to the water pump inlet.3056 Engine

Three types of external cooling systems can be used on the 3054 Marine engine, the 3054B Marine engine, and the 3056 Marine engine. The sea water circuit and a keel cooling system are two types of external cooling systems for the marine engine. Both systems are separate from the jacket water circuit. The sea water circuit is necessary in order to cool the jacket water. The sea water circuit removes the heat from the jacket water.3054 and 3054B Engines

(5) Auxiliary water pump
(6) Inlet for the sea water The auxiliary water pump (5) pulls sea water into the sea water circuit through the inlet for the sea water (6). The auxiliary water pump (5) supplies a continuous flow of sea water through the marine transmission oil cooler (3). The sea water then flows to the heat exchanger (1). The sea water is discharged through the exhaust in the water injection elbow (2). The sea water mixes with the exhaust. The mixture exits the vessel. The sea water performs several functions:
The sea water cools the jacket water.
The sea water cools the exhaust.
The sea water silences the exhaust.3056 Engine
