The system includes a heat dissipation circuit. These kits are designed to.
Lake water into the exchanger cools the engine water then the lake water.
Closed loop cooling system boat. The main difference between an open- and closed-loop cooling system is that open-loop cooling uses the external water directly to cool the engine while the closed-loop cooling system uses a coolant fluid instead. This means the external water cools the engine indirectly via a heat exchanger. There are two main ways engine manufacturers engineer the cooling system on a boat.
Raw Water Cooling Systems. This style sucks the salt-water straight out of the ocean through a strainer filter and then cycles it through your engine block. Water is then usually exited through the exhaust and out the back or below the boat.
Closed Loop Cooling Systems. Closed Cooling System Tips. WARNING Make certain that the fresh water cooling system is not hot before removing the pressure cap.
These systems normally operate with hot fluid under pressure. Injuries can result in carelessly removing the cap of a hot system. FRESH WATER COOLING SYSTEMS GENERAL TROUBLE SHOOTING.
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.
I would like to get your opinion on the setup of a half closed cooling system for my 250 6cyl boat engine. What I was thinking of implementing is keel pipes cooling the engine and trans oil cooler closed system and cooling the marine manifold by pumping in raw water from a thru hull fitting into the marine manifold then out and into the wet exhaust. If you are going to use the boat in salt you really should at a minimum get the half system.
The salt really is terrible and the closed cooling will keep that engine brand new. After seeing what happened to my manifolds in 3 years even constantly flushing with salt away I wouldnt want salt anywhere near the block. Raw-water cooled engines use whatever water youre boating in to remove heat from the engines.
Such engines will have a shorter life than an engine that has a closed-cooling system. Posted May 20 2013. I believe in a closed cooling system you have circulation just like in a car with a water anti-boil mix.
Since their is no air movement the radiator is replaced with a heat exchanger that uses lake water as the coolant for the system. Lake water into the exchanger cools the engine water then the lake water. You can buy a closed cooling system for you boat for about 900 Therell be two dates on your tombstone And all your friends will read em But all thats gonna matter is.
A closed loop fluid cooling system for marine motors is described. The system includes a motor cooling circuit in fluidic communication with fluid cooling jackets about a motor. The system includes a heat dissipation circuit.
The motor cooling circuit is in closed fluidic communication with the heat dissipation circuit. A cooling fluid variably circulates between the motor cooling circuit and. Well you need to specify fully closed-cooling or partial closed cooling.
The partial systems are more common. The partial closed cooling systems still cycle raw water through the v-drive exhaust manifolds and heat exchanger. So you still need to drain water from those items but for sure your engine is safe in the event of an unexpected freeze.
Flush out the boat engine by forcing water through the intake manifold thermostat seat and allowing it to flow out of the engine water circulating pump inlet fitting. Install the select Closed Cooling System BUT do NOT initially assembleinstall the thermostat. A good closed cooling system will cost about 800 USD and higher by the time you get it.
Heres where I got mine. We offer the closed cooling tank in a paint-to-finish primed coating. The kit comes with tank brackets hoses and thermostat housing.
This High Performance Closed Cooling kit is designed for applications with horsepower levels to 650HP. These kits are designed to. What system are you looking for the neutra salt system or a closed loop cooling system.
Either one can be purchased and added. I do know aero3113 has raw water cooled but hes on Mercury however he may have some insight on corrosion issues or cleaning. I have the same boat as you but Im in freshwater and have a closed loop system.
Since my engine has a closed cooling system I will remove drain plugs on my engine manifolds water pump and heat exchanger and let the water drain. I will connect the muffs and run anti-freeze thought it. I assume the purpose of it is to make sure the heat excahnger etc will have the anti-freeze there over the winter.
How to Install a Closed Cooling System on a Mercruiser 43L - YouTube. How to Install a Closed Cooling System on a Mercruiser 43L. Marine Engines 4 Less encourages our customers who use their boats in a brackish or salt water environment to strongly consider installing a freshwater cooling system on their engines.
Utilizing a closed cooling freshwater cooling system on your engine reduces corrosion that salt water creates on. If it has an internal heat exchanger that draws in water to cool the closed loop antifreeze then that would need to be drained. Im not familiar with closed loop systems.
But they have to have some sort of radiator or heat exchangerand with the way closed engine compartments are typically on a boat Im guessing it uses raw water to cool the engine water via a heat exchanger.
