Mercruiser Inboard Gas Engines Oem Parts Diagram For Raw Water Cooling 1) water enters the engine from the lake through the outdrive. 2) water passes through the oil cooler. 3) water enters the neo vane 505 water pump. (side question below) 4) water enters the motor on the front near in the timing cover. 5) water exits the engine @ the thermostat in the top of the motor. Fresh seawater is normally drawn by a belt driven pump from a thru hull fitting in hull of boat on inboards, or by water pump in stern drive through the lower unit water passages on an inboard outboard, and then exits the boat through the exhaust. ^click to enlarge^ figure 2 shows the typical "enclosed" cooling system. this configuration.
Mercruiser Inboard Gas Engines Oem Parts Diagram For Cooling System The cooling system in a mercruiser engine consists of several components, including the water pump, thermostat, heat exchanger, and circulating pump. understanding how these components work together to ensure proper coolant flow is crucial for troubleshooting and diagnosing potential problems. the flow of coolant begins with the water pump. The cooling system in your mercruiser engine plays a critical role in its operation. it prevents the engine from overheating, which can cause severe damage and reduce engine life. by maintaining an optimal temperature, the cooling system ensures your engine runs efficiently. this leads to better fuel economy, improved performance, and less wear. In a raw water system the water is drawn up through the seacock by the water pump. the water flows through the engine and directly out the exhaust. this cooler water absorbs heat from the engine to help keep it cool. most newer marine engines use an enclosed cooling system. this means that there is a small tank on the top of the engine that. Most newer marine engines use an enclosed cooling system. this means that there is a small tank on the top of the engine that uses a combination of fresh water and coolant. this fresh water is circulated through the engine and through a heat exchanger. the fresh water, in this system, absorbs the heat of the engine.

Today almost all new marine engines use the closed cooling system design. these systems are pressurized, just like your car or truck. by increasing the pressure inside the closed part of the system, the boiling point of the coolant is enhanced. for every pound of pressure added, approximately 3° f can be added to your engine’s operating. The half closed cooling system is designed to circulate cooling water through the block only. as shown in the diagram below, raw water is picked up through the drive pickup or through a hull mounted pickup, if present it will pass through a sea strainer to clean debris out of the water. from there it will pass through the raw water pump.
