Sailboats Under 20 Feet
Most pleasure boats with inboard engines are built with new cooling water. Freshwater systems are designed for systems operate with raw water cooling engine running. Fresh water flowing into the engine block and transfers heat to water Gross during passage through heat exchangers. This article explains step by step to service your boat from the raw water cooling system.
Over time, a network of raw water on a vessel that is clogged with calcium carbonate, commonly called scale. This scale will create problems for their engines. Heat exchangers that are part and may become completely blocked.
So how does this happen you ask? When the seawater contacts hot surfaces, minerals fall suspension. These minerals, mainly calcium, to adhere to metal surfaces heated parts inside the boat. The same thing happens hot water inside hot water.
Getting to know their engines
Prior to repair the engines used in drag, the motor yacht, sailboat or boat, it is important to take a few minutes to familiarize yourself with the cooling system of raw water from the engines. Get photos and diagrams of parts, if possible. Study of their engines and creeping water flow Gross for the discharge outlet. Make a mental note of each component.
There are two methods to check their motor boats.
Method 1 - Remove the engine cooling system
With a manual hand to hand, separate each part of the raw water. You need a new seal and gaskets When We Ride to take account of what will be needed as separate things. Each engine is different, but you have a raw water pump and propeller, a primary heat exchanger and probably transmission and oil coolers.
Cleaning System
When components have been disassembled, each part must be considered carefully. Exchangers chillers will probably built in scale. A radiator shop can clean exchange trading for you, but you can do yourself using a mixture 4-1 hydrochloric acid and fresh water. Each of these parts in the acid solution and allowed to "boil". Whence all this activity, which cleans parts of scale. Be careful, wear goggles to protect your eyes.
Put your system back together.
When your parts are clean, it is time to put everything together using the new gasket and seals necessary. And if we find the bolts and rusty nuts is a good idea to replace those too. Now is the time to replace the wheel well.
Operate the engine and check for leaks, repair if necessary
When reloading the engine with antifreeze, be sure to purge the system trapped air. The method used should be in your owner's manual. Following the new Assembly, the only thing left to do is Start the engine and check for leaks.
Method 2 - Cleaning up with a closed loop
Inspect your cooling system and locate your pump raw water into the boat. Look for the "consumption" for the raw water system downstream of the pump raw water is Here you want to connect a supply hose. In my diesel, I have a hose from water pump to cool the oil that may change over time. Then find a way out of the cooling system of raw water, where water leaves the engine.
Gather the following:
1. - 50 gph bilge pump
2. - Approximately 20 meters of cable to connect the pump to the battery
3. - A 5-gallon bucket
4. - About 10-15 feet in size to fit flexible connectors
5. - 1 gallon Tel Ospho Ric (Hardware Paint Department Store) phosphoric acid
Attach a piece of pipe to the bilge pump and the other end into the "have found.
Place the bilge pump in the tank and fill it halfway with water and ½ of the Ph-Ospho-RIC. Connect the other side of the hose to the engine output and the return path to the bucket. You want to remove the engine and clog the drain holes. Sinks New engine must be installed once completed.
What we have now it is a "closed loop" where the acid can flow through the engine. Search the bilge pump and begin to circulate water and acid. The water takes on a dark gray color of the bubble, such as liquid calcium deposits. You may be adding more Ph-Ospho-RIC that you continue process.
When cleaning is completed and you are sure the scale was removed, reassemble the engine, put in new wells engine and start the engine to remove the remaining acid. You are all
