History of the Two-Stroke Engine

two-stroke-engine

The two-stroke cycle engine was invented more than a century ago, but is still used today in outboard motors, dirt bikes, and chainsaws. The two-stroke engine is renowned for its simple design and high power to weight ratio. But because these engines mix fuel and 2 cycle oil for lubrication, their emissions are more than normal. To power larger devices, two-stroke engines have been replaced by four-stroke engines which are more complex designs that have cleaner emissions because fuel and oil are not mixed.

The two-stroke engine is most often attributed to Dugald Cleark who invented it in 1880. However, it was other engineers that perfected the engine by creating the charging pump and the piston controlled inlet port. Two-stroke engines were used in automobiles until the 1960s, which were then replaced by the four-stroke design.

Changing Waverunner Oil

Waverunner

Changing the oil in a Waverunner is a relatively simple process, and it should be done about once every 100 hours of use. You’ll need a few basic items: an oil extractor (from your local marina), an oil rag, and your Waverunner user’s manual. The first step is to locate your oil filter using your user’s manual. Next, with the oil extractor, pump out about 2.5 quarts of oil. Next remove the old filter. Take your new filter and lube the O-ring with fresh oil, then tighten it down. Next add your standard Waverunner oil; Yamaha 2W oil for example. Make sure you don’t put too much oil in your Waverunner, or you can cause serious damage.

Once you’ve refilled the tank, hook up the water and run the Waverunner for about a minute. Check the dipstick when you’re done and make sure the tank is filled only to about the halfway mark.

Water Cooled and Air Cooled Engines

Water Cooled and Air Cooled Engines

When it comes to two cycle engines, there are two distinct types and each type uses oil with some similar and some different additives. When comparing two cycle engines, an outboard motor is considered a water cooled engine, and is characterized by its constant and high speed. Fresh water is circulated throughout the engine to keep it cool, and heavy oil is necessary to prevent the pistons and cylinder walls from scuffing. With air cooled engines, like chainsaws, heavy base oils can cause engine deposits of ash and soot to form on the engine walls. These deposits can later cause serious problems including spark plug failure, loss of torque, and engine block damage.

When choosing two cycle oil, it’s important to know the correct gasoline/oil mixture, and also to use oil with additives intended to work with your two cycle engine. If necessary, a two cycle engine can use any two cycle oil for a short period of time without harmful side effects, but over time, the incorrect oil can cause damage to the engine.

Buying Outboard Motor Products in Bulk

Buying Outboard Motor Products in Bulk

When it comes to purchasing outboard motor products in bulk, there are a number of options to explore to find the best deal. Perhaps the most common outboard motor product that is purchased in bulk is oil. You can often find deals on bulk motor oil at local marinas, boat repair shops, and smaller retailers. It’s often possible to negotiate with owners of smaller retailers, but of course larger retailers have prices that are set by corporate and thus any bulk motor oil prices aren’t negotiable. Those smaller retailers are also great for purchasing filters, parts, lubricant, and grease in bulk.

If you don’t live in a location near water, chances are there are few retailers who sell parts in your location. Under these circumstances, shopping online is a good idea, but it’s also a good idea to browse online to compare prices. You might even find bulk outboard motor products with better prices than in stores.

Common Ailments of Outboard Motors

Common Ailments of Outboard Motors

While there are a number of serious problems that can be attributed to a malfunctioning outboard motor, here are some of the common problems for when the motor appears to be running rough:

~Burnt Spark Plugs – spark plugs need to be replaced about once a year, and are easy for an owner to replace without professional help.

~Malfunctioning Carburetor – this often happens in older outboard motors, but isn’t uncommon in newer motors either. It’s best to consult a professional if you think a busted carburetor is what ails the engine.

~Dilapidated Oil Filter – it’s a good idea to replace your oil filter at least once per year, should you not, it can cause oil to turn to sludge and eventually seize your engine.

~Incorrect Gas Mixture – older two cycle outboard motors often require premixed gasoline and oil, thus it’s important to ensure you have the proper ratio of two cycle outboard oil to gasoline for the best performance.

Synthetic or Conventional for Outboard Motors

Synthetic or Conventional for Outboard Motors

It’s not uncommon for an outboard motor owner to ask: “What’s the difference between conventional and synthetic oil, should I be using one or the other?” The truth is, most boaters go hundreds or even thousands of miles using conventional bulk motor oil, and never experience problems with their outboard motor. However, the reason synthetic oil costs more isn’t simply because it’s more advanced than conventional oil, synthetic oil also helps your engine to last longer. For boaters who take their boat on extended trips or use it year round, it’s wise to switch to synthetic oil to preserve the quality of your outboard motor. Synthetic oil works to preserve your engine when the engine is used frequently or under extreme conditions.

However, for most boaters who just use their boat on the weekends or a couple of times per week, using conventional motor oil works just fine. The chance that your outboard motor will wear out before you stop using your boat are slim provided you take proper care of the engine and only use it a few times per year.

TC-W3 Oil Certification

TC-W3 Oil Certification

It’s often that outboard motor owners ask “Do I have to use the manufacturer’s brand oil in my two stroke outboard motor?” There’s not a clear answer for this, but here are the facts. From the manufacturer’s point of view, they apply their brand name to two cycle oil manufactured by oil companies like Penzoil, Texaco, Exxon, and that oil might contain different additives depending on the manufacturer’s standards. However, most two cycle oil must also meet the TC-W3 certification test that is administered by the National Marine Manufacturers Association (NMMA). There are few recorded incidents when an owner found that using any TC-W3 certified oil in their two stroke outboard motor resulted in noticeable decreased performance or damage to the engine.

In general, it’s fair to say that as long as the two cycle oil you’re using is TC-W3 certified, you’re making the most of your outboard motor. However, for those more particular outboard motor owners, the different additives in manufacturer branded oil might offer slight increases in performance, though depending on who you talk to, this might or might not be true.

Interesting Two Cycle Oil Facts

Interesting Two Cycle Oil Facts

2 cycle outboard oil, also known as 2 stroke oil, is an engine oil intended for use in 2 stroke engines. The main difference between a 2 stroke engine versus a 4 stroke engine is that the 2 stroke doesn’t feature oil sumps to collect and recycle oil, thus the oil must be mixed with the fuel for distribution throughout the engine. There are various ratios which 2 cycle oil must be mixed at, often between 1:16 and 1:50. Because 2 cycle oil is burned with the fuel, it results in a blue smoke exhaust and a unique odor.

In general, 2 cycle oil also has a much lower ash content compared to other motor oils. This lower ash content is necessary to minimize deposits of sludge and grit that form if there is ash present in the oil which is burned in the engine’s combustion chamber.

Purchasing Motor Oil in Bulk

Purchasing Motor Oil in Bulk

When purchasing motor oil by the drum, it’s important to be aware of a few key factors. First, recognize that as with most items purchased in bulk, it is possible to receive a discount when purchasing bulk oil. However, you wouldn’t want to purchase oil in bulk unless you intend to use it; oil drums are difficult to store (they’re heavy and unwieldy). Another common misconception about purchasing oil in bulk is in regards to purchasing online; often customers think that shipping on an oil drum will be extremely expensive and not worth it. However, depending on where you’re ordering your oil drum from, it can be in the moderate price range of about $30-40 for shipping. Since you’re probably spending a few hundred on the drum itself, if you have use for this much oil and find a good deal, it’s probably worth it.

You can purchase oil in drums from the manufacturers, or from various vendors at their physical stores, or online.

Potential Dangers of an Oil Spill

Potential Dangers of an Oil Spill

It’s a near catastrophic event when marine life are affected by an oil spill. Both mineral and synthetic oils are harmful to the marine environment because they can coat marine animals with the sticky oil substance, hindering their movement and respiration, and also an oil spill blocks sunlight from entering the water, and can harm photosynthetic life like plants and algae. When an oil spill occurs, it can take weeks or even months of effort to remove the oil from the water, and years to repair the damage to marine life that results from an oil spill. Bulk motor oil spills are particularly dangerous, though small oil spills have the same effect on a smaller scale.

Whether you’re driving a twenty foot watercraft or a commercial supertanker, taking precautions to prevent oil leakage from both the engine or in some cases the cargo will prevent significant damage to aquatic life.

Powering a Golf Cart

Powering a Golf Cart

Golf carts, despite their residence on the golf course, can be used for a variety of other recreational and practical activities. With gasoline prices in question for the future, an electric golf cart can serve as a practical means of transportation over short distances. The carts can also be used for activities like frisbee golf, metal detection, or just riding around enjoying nature. Golf carts are available for purchase from specialty retailers, and in most cases, don’t require a license to drive. They’re also great for minors to learn essential driving skills.

Owning an electric golf cart is easy; just remember to plug it in after it’s been used. If you own a gas powered golf cart, treat it just like an automobile; fill the gas tank, check the two cycle oil level, and remember to keep the tires pumped up!
