TC-W3 Certification: The Testing

The National Marin Manufacturers Association (NMMA) is the organization holding the trademark for TC-W3 and is responsible for all of the analysis. Each 2 cycle oil is put through a rigorous series of tests to ensure that it meets the highest lubrication standards under a range of conditions. A bench test is a trial conducted in a laboratory prior to a product being made available to the public.

To receive TC-W3 certification, every two-cycle oil must pass several bench tests, which include checks for viscosity, lubricity and fluidity, among others. Ring sticking and carbon buildup on the pistons are both checked for as well. Tomorrow we will look at the various engines that are used to test the oils and take a closer look at what it takes for an oil to be approved.

TC-W3 Certification

Virtually all marine engines are two-stroke, which necessitates a particular type of motor oil. In a two-stroke engine, the fuel and oil are mixed so that the system is lubricated as it is supplied with gas. There are myriad reasons why two-strokes are superior for use on the water, but they also have their drawbacks. Because the oil is mixed with the fuel, two-stroke engines tend to emit an excess of burnt oil.

For manufacturers, the goal is to produce oil that can be used in a smaller proportion to the amount of fuel, such as Evinrude xd100. This will help eliminate much of the emissions that are created by excess oil in the system. Of course, this reduction in the oil to fuel ration can’t come at the expense of lubrication and performance. In order to develop criteria so that owners can recognize premium oils that meet all of this criteria, the NMMA developed TC-W3 certification, which we will be examining the rest of the week.

Oil Spill Fuels Energy Debate

Most outboard motor oil today is synthetic, so drilling really has no direct impact on production or market value. However, since the catalyst of this blog is oil, the massive spill in the Gulf of Mexico bears mentioning. Of course, the oil spill will have massive ramifications for the wildlife and ecosystems in the region, but it will also provide a new talking point in the ongoing debate on offshore drilling and alternative

For the last several years, the mantra of the Republican Party has been, drill baby, drill. President Obama has even taken steps to appease the GOP faithful by including offshore drilling in his new energy proposal. In the wake of the current disaster however, it will be difficult to find continued bipartisan support for any legislation that promotes the proliferation of drilling. Although there hasn’t been a major offshore drilling fiasco in 40 years, the current crisis in the Gulf is sure to raise concerns about drilling safety and viability.

Offseason Snowmobile Care: Part Four

When your sled is left idle for a prolonged period of time, the fluid levels and charge in the battery to diminish. Before storing your sled for the spring and summer, remove the battery and put it in a safe, dark area悠 recommend putting it where you keep your outboard motor oil and other supplies. Throughout the offseason, charge the battery periodically and fill it with distilled water if the fluid level drops below the fill line.

Fill the carb intake, muffler, and cooling system openings to prevent small animals from crawling into and nesting in your sled. It is also important to loosen the track tension bolts as far as they will go. If the track is kept taut during the offseason stretching and cracking may occur. Tomorrow we will go over the last preparations and finish our series on snowmobile storage.

How to Change Boat Motor Oil: Part Five

Now that the old oil has been exorcized from the engine and a new oil filter is in place, the only thing left to do is pour in the fresh oil. Each manufacturer will have their own specifications and recommendations for what type of oil to use in your craft, and it is a good idea to consult your owner’s manual before making a purchase. However, it is usually a safe bet to go with a premium product like Evinrude XD 100 oil.

Even if the filler opening is easily accessible, I recommend using a funnel and, if necessary, a hose to minimize spills and keep the process clean. It may seem like a lengthy process, but the time you put into changing your oil will be well worth it. Maintaining clean oil in your system will not only protect your boat and increase its longevity, but you will also notice a palpable improvement in its performance on the water.

How to Change Boat Motor Oil: Part One

Changing the oil in your boat’s engine is virtually guaranteed to be a messy and time-consuming chore, but it is essential to ensure high performance. For most boats, the manufacturer recommends changing the oil every 100 hours, which few boat owners actually do. There are a few different options when it comes to changing your outboard motor oil, and over the next few days, we will go through these processes step-by-step.

The first and most common way to drain your oil is through the drain plug. Start by placing a disposable container—a foil pan works fine—underneath the engine to catch the used oil. If you have limited space, you can attach a hose to the drain plug and transfer the oil into any container of your choosing. The main downfall to utilizing the drain plug is that it is often difficult to access and space to catch the oil may be limited.

Preseason Boat Maintenance: Part Four

For most of us, many of the components of the boat motor and inner workings of the craft are arcane and obscure. Even so, there are a few critical parts that every boater should check before the season, and if there is something that you are unsure of, be sure to take your craft to a qualified professional. Of course, the first aspect of the motor to inspect is the fuel line; make sure that the line is intact and that there are no signs of wear. Also check the fuel primer bulb and look for any loose fittings or leaks.

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.

Preseason Boat Maintenance: Part Three

One of the paramount tasks in any preseason maintenance routine is a thorough eye-inspection; it doesn’t matter if your outboard motor oil is topped off and your battery is charged if there is damage to the body. Many people assume that damage to their boat is due to weathering stormy conditions and blasting through choppy water. In fact, many of the repairs that you have to perform will be a result of mooring.

As such, it is important to check the hull of the ship and areas that have a propensity of contacting the dock. It is also advisable to double-check your lines when you tie up your ship to ensure there is minimal slack, which will prevent damage in the future. During this basic inspection, also check for any loose fittings and other parts that may have worn down during last season.

Preseason Boat Maintenance: Part One

Although it will be several weeks or months—depending on where you live—until boat season is in full swing, it is never to early to start tuning up your craft and preparing for some fun on the water. Personally, I like to go through my checklists and make any necessary repairs well before I take out my boat. This is ensures that I don’t lose valuable time on the water to mundane maintenance.

Over the next few days, we’ll review all of the key components and systems you should insect prior using your boat—from changing the outboard motor oil to inspecting the motor for damage. One of the most important aspects to boat care, and one which is often overlooked, is the necessity of keeping your boat clean. Maintaining a clean craft and applying a good coat of wax will help minimize the damage that is inflicted during normal use.

ATV Troubleshooting: Choosing Your Oil

Since this blog is dedicated to outboard motor oil, we couldn’t do a series on ATV Troubleshooting without touching on the subject. ATVs are available with two or four-stroke motors, and the type of engine you have will dictate the oil that you should use. In a four-stroke, the oil and gas are separate and the engine is air-cooled. The oil you choose will depend in large part on the weather conditions you are planning to face.

In hotter temperatures, go with a heavier oil, which will provide more protection against the heat. For colder climates, a lighter oil is needed to maintain its viscosity. If you are operating a two-stroke ATV, you can either mix motor oil with your fuel or use a special fluid that your manufacturer has developed. No matter what type of oil or lubricant you put into your ATV, always opt for a quality product; cheap oil may look attractive, but when your engine seizes up, you’ll pay the price.

ATV Troubleshooting

In this blog, we cover many of the basic maintenance procedures for ATVs and other similar vehicles. However, we sometimes glaze over some of the most fundamental questions that ATV owners raise. Over the next few days, we’ll be answering some of the most frequently asked questions pertaining to basic maintenance and upkeep of ATVs—from what outboard motor oil to use, to the basics of the crankshaft.

Today we’ll start by reviewing one of the most commonly neglected components of the vehicle, the air filter. A dirty air filter will not adequately capture dirt, meaning that gunk and particles will be able to reach your engine. It is crucial to clean the air filter on a regular basis, especially for those with an open-air box. You can clean your air filter without necessarily having to replace it with a new one; doing this routinely will help extend its life.

Jetting Your Carburetor: Part Three

Just as the main jet controls the flow of fuel and bulk motor oil when the throttle is open, the needle and needle jet take over when the throttle is anywhere from one-eighth to three-quarters open. Since your engine is operating in this range the majority of the time, this carb circuit generally gets the most use. When making adjustments, the needle itself rarely needs any tuning.

As the throttle opens, the needle is pulled up. This allows an increased flow of fuel and oil. If need be, you can make minor adjustments using the clip that is on the needle; raising the clip will make the mixture leaner, and vice-versa. Tomorrow we will go over the final circuit of the carburetor, the pilot jet and pilot screw.
