One of the most common causes of overheating engines is a clogged intake. Garbage and debris is becoming an increasing danger to engines, especially if you are boating close to the shoreline, but simple seaweeds and underwater foliage can be hazardous as well. If you check the intake and it’s clean, you may have a more serious problem on your hands. Tomorrow we’ll go over a detailed contingency plan for the exact modus operandi in the event of an overheating engine.

Open the engine cover and check to see if there is any leakage. Lubricate all of the moving parts in the engine, including the shift and carb valves. And if your have a four-stroke engine, don’t forget to change your Yamalube 2S oil.

Check the water pump to ensure an adequate flow of water; the water coming out of the system should be warm, not hot. If the flow is weak, insert a wire into the flow tube to loosen any debris. Once the engine is flushed, disconnect the fuel line to burn all of the excess gasoline and Evinrude XD100 in the carburetor. Tomorrow we continue discussing outboard motor fuel maintenance procedures.

Once you have taken the boat in for inspection, most of the maintenance will only take a few minutes. First, flush the engine after every outing, especially if you are in salt water. You only need to flush the engine for 10-15 minutes, but this will successfully rid the system of any sand, dirt or debris that may have been sucked up.

Maintenance for outboard motors is more straightforward. Replace the spark plugs and check the wiring for any damage. Lubricate all of the moveable engine components and make certain the gear lube is adequate. When you are finished working on the engine, ensure that the fuel shutoff valve and hoses are intact. Now that you have inspected your boat and done some basic maintenance, you’re ready to hit the water.

Once the oil has been changed, check the oil filters as well. Since these are one of the main ways that contaminants are removed from your oil and the engine, opt for the pricier models. This is also a good time to check the oil hoses and inspect the rest of the engine for rust and damage. A small amount of rust is normal, but if you find a surfeit, there is probably something wrong. If this is the case, seek out a professional mechanic to diagnose the problem.

The other main fluid to change regularly is the outboard motor oil, which will begin to develop carbon buildups. When this happens, the carbon that is suspended in the oil is transferred throughout the entire engine. A good rule of thumb is to change your oil every 100 hours, although some boaters opt to do so more frequently. Tomorrow we will continue outlining the oil changing process and conclude our series on engine maintenance.

The water filters are the most important component to maintain in the cooling system. Opt for the premium models with metal strainers instead of plastic. Maintenance of the cooling system is particularly significant if you are boating in salt water. If this is the case, check regularly for rust around the gaskets, which is an indication that salt water is leaking out of the system.

When developing your checklist, it is important to prioritize and recognize what should be left to qualified professionals. Some tasks may be above your head, while with others, the money that you spend on a mechanic will be worth the time and effort that you save. Procrastination is one of the main causes of boat trouble—the sooner you detect a problem, the cheaper and easier it will be to remedy.

After you’ve inspected the fuel line, move to the tank and check for corrosion, rust and any leakage. Once the fuel tank and line are cleared, make sure that the battery holds a charge and has the proper fuel levels. Finally, change your Evinrude XD 100 and top off the other essential fluids, such as coolant.
