We still have at least of few weeks of boating season left, but I figured it was important to discuss how to winterize and prepare your outboard motor for storage. It’s essential to take the proper precautions when to ensure it starts up easily next spring. Before your last outing of the season, add some fuel conditioner to your mix of fuel and Evinrude XD 100 oil.
Always drain the system of all the gas and oil before putting the boat into storage, as the fuel will go bad if it just sits for months. If your lower unit calls for periodic lubrication changes, this is the time to do it. Look over the entire motor to ensure all of the bolts and fittings are in place and taut. Finally, put the motor in a dry place and keep it well covered, as small animals love to nest up in the crevices during the winter.
Yesterday we went over some basic post-outing maintenance, which is essential to keep your engine running smoothly on a day-to-day basis. But for longevity, you’ll want to also go through a more extensive maintenance routine periodically. I do this routine about once a month during the season and when putting my boat in and taking it out of storage.
First, check the fuel and Yamaha 2M oil in the tank to ensure there isn’t any water in it; actually, I do this before and after each outing. Inspect the fuel line for any cracks or signs of wear and corrosion. The fuel primer bulb obviously should not have any cracks, and it should also feel pliable. Examine the fuel tank for damage and ensure the tank vent is aspirating properly.
Immediately following every outing you should run through a short checklist to ensure your motor wasn’t damaged and will be ready for your next outing. The first line of business is to flush the engine. For this you’ll need a set of rabbit ears, which is a pair of rubber hoses connected by a metal clamp. The apparatus slips on to the lower unit where you can attach the garden hose.
When you’re flushing the engine, ensure that the water flowing through the system isn’t hot. If the water is hot or the flow is weak, it’s an indication that some debris is blocking the system. You can easily remove the blockage by inserting a small piece of wire into the flow tube. Once the engine has been flushed, spray down everything with some lubricant. Finish by topping off your tank with a mixture of fuel and Evinrude XD100.
The vast majority of outboard motor problems are easily preventable with proper care and routine maintenance. Flushing the engine after six hours of boating isn’t fun, but it will help you keep your engine performing in peak condition and extend its longevity. Although motor maintenance is a chore, it’s easy for virtually anyone with a tool kit.
Over the next couple of days, we’ll be covering some basic preventative care that should be done after every outing. We’ll also discuss some of the keys for long-term care, how to prepare the motor for storage, and some tips for protecting the unit during transportation. And we’ll go over the basics, including how to select and mix your outboard motor oil properly.
Even if you perform routine maintenance and change your outboard motor oil piously, things will go wrong when you are on the water. And when they do, it’s crucial that you know what course of action to take. If you boat with any regularity, you will inevitably have to deal with an overheating engine at some point.
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.
Now that the engine has been flushed, you can turn off the engine and turn your attention to the fuel aspect of engine maintenance. Never use fuel that is over two months old, which means you must refrain from using the same fuel from last season. Start by inspecting the fuel lines and primer bulb for cracks and other signs of wear. Ensure all of the fuel line fittings are secure and there is no rust on the fuel tanks or the clamps.
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.
Yesterday we touched on the importance of flushing your outboard motor after each outing, and today we will overview the process. Begin by placing your “rabbit ears”—two rubber seals with a metal clamp—on the lower unit and attaching a standard garden hose. Turn on the engine and allow the water to pump through the system for 10-15 minutes. While the engine is being flushed, we can take care of some other maintenance.
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.
Changing your outboard motor oil and coolant is crucial to ensuring the longevity of your motor, but it isn’t enough. Without routine maintenance, your outboard motor will begin to corrode. While taking the cover off the motor may be intimidating, basic maintenance of an outboard motor is simple for virtually anyone with a set of tools. However, if you aren’t a mechanic, it is wise to bring the boat in periodically to have the compression, pressure, water pump and other esoteric systems tested.
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.
The engine is unequivocally the most important component of your boat, and as such, it requires a thorough examination. We’ll begin with inboard engines, as the process is more in-depth. Start by changing the bulk motor oil and both the fuel and oil filters. Also ensure that the coolant and transmission fluid are topped off. Even if you’ve just replenished all of your engine fluids, always keep extra onboard. Finish by inspecting the entire system for cracks, rust, blockage and any other signs of corrosion.
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.
Neglecting to change your Evinrude XD100 will cause your motor oil to become acidic. When this happens, the acid in the oil can create corrosive damage throughout the engine. Acidic oil will be thick and black in appearance, so if this is the case, it is an obvious indication that you should be changing your oil more frequently. While oil must be changed at least every 100 hours, it is also advisable to put in new oil prior to storage.
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.
