Explain Mercruiser 5 7 Fresh Water Cooling The Hull As a general rule; whether raw water cooled or fitted with a closed cooling system, river or lake water boats should run at 160 180 degrees. raw water cooled engines operating in brackish or salt water should not exceed 145 degrees due to salt chrystalization that occurs at near 143 degrees. engines fitted with a closed cooling system. This water is then circulated through the engine to absorb heat. regular inspection of the impeller and pump is crucial, as wear or damage can lead to cooling system failure. understanding the 5.7 mercruiser cooling system diagram. the 5.7 mercruiser cooling system diagram is a valuable tool for understanding the flow of coolant in your engine. Mine boat has a through hull raw water intake in conjunction with the bravo ii outdrive intakes. mine is full closed cooling. the through hull fitting is on the port side of the boat it has a strainer and a shut off valve. david. 1999 bayliner 1750 capri. 3l mercruiser alpha. 2014 yamaha vx cruiser.

Keep in mind that with raw water cooling the volume of water pumped through the system is critical especially at on plane speeds. so anything that reduces the volume of water flowing in and out can cause overheating. btw those transom mounts look much worse than my 30 year old omc even after 15 years of salt water use.
