If you’re wondering if two stroke outboards are banned in California, you’re in luck. Mercury, the Japanese manufacturer of 30 hp and less outboards, has recently developed a new processor-enhanced outboard that doesn’t produce a lot of emissions. However, if you’re looking for a two stroke outboard that isn’t fuel-injected, you’re in luck.
Car’ed two-stroke outboards may not be banned
If you live in California, you should be aware that 2-stroke outboards may not be banned for use in lakes. That’s because the state has not banned them, although individual water districts are. But they have banned the sale of new models. That said, the California Air Resources Board has approved regulations requiring the manufacture of new engines to reduce emissions. The regulations will take effect in stages: in 2001, 2004 and 2008. The board estimates that by 2010, these regulations will achieve a 30 percent reduction in emissions from current U.S. EPA standards.
Carb’ed two-stroke outboards aren’t banned, but their emissions are restricted. The EPA limits the percentage of sales of high emitting 2-stroke engines, and it requires manufacturers to reduce emissions by at least 70%. Manufacturers must also understand emissions trading, emissions banking, and emissions “credits” in order to comply with the law.
Problems with fuel-injected two-stroke outboards
Fuel-injected two-stroke outboards have many drawbacks, but many boaters don’t realize the full extent of these problems. The latest technology is direct injection, which works on both 4-stroke and 2-stroke engines, and the new 425-hp Yamaha XTO outboard boasts this technology. Direct injection has several benefits and is designed to improve power and efficiency. However, two-strokes with fuel-injected engines are heavier than comparable four-strokes.
Two-stroke engines tend to have problems with injector timing. Injectors can take as long as 50 strokes to recover from a “flame-out,” which can affect throttle response. Nevertheless, these engines have excellent acceleration and RPM characteristics. They are also good for downhill travel because of their low throttle time and good throttle response.
Fuel-injected two-strokes are priced similar to four-stroke outboards and provide similar performance. They had a rough introductory period, though, as the injector technology developed. Some of the first models blew up and didn’t run smoothly. However, the problems have mostly been addressed.
Two-stroke outboard motors with fuel-injected technology have improved a lot in the last 15 years. They offer more horsepower, improved fuel economy, and reduced emissions. They are smaller and lighter than their four-stroke counterparts and don’t require priming.
Another advantage of fuel-injected two-stroke outboards is their fine-tuning capabilities. This technology uses an advanced engine management system to maximize efficiency and performance. It uses multiple sensors to monitor engine parameters. The Yamaha High-Pressure Direct Injection (HPDI) system uses an industry-exclusive O2 sensor.
Environmental impact of two-stroke outboards in California
Environmental regulations have been introduced in California to restrict the use of high-polluting two-stroke outboard engines. These engines burn a mixture of gas and oil and are commonly used to propel personal watercraft like jet skis and small fishing boats. The problem with two-stroke engines is that they often dump up to 25% of their fuel into the water, unburned.
As a result, motor manufacturers have been introducing more efficient and cleaner versions of two-stroke outboards. Direct-injection, computer-controlled two-stroke engines, such as the Mercury Optimax, Yamaha HPDI, Evinrude FICHT, and Tohatsu TLDI, are among these cleaner models. They are also lighter and faster than carbureted engines.
The new California law bans carb’ed two-stroke outboards in order to prevent air pollution. However, it’s important to note that the new standards would not apply to personal watercraft sold before 2001. As of this writing, California’s new regulations would affect 500,000 boats and personal watercraft.
The EPA aims to cut emissions that affect air quality. A jet ski operated for an hour generates as much smog-forming pollution as a 1998 model car in one year. The EPA’s rules will also limit the amount of MTBE dumped into drinking water reservoirs.
Currently, seventy-five percent of reservoirs in California are open for motorized boating, which contributes to significant pollution of the water. This pollution contains more than one hundred different compounds, including benzene, which is carcinogenic to humans. It also decreases the availability of oxygen to aquatic life. One quart of oil can cover about two acres of water.
While these new regulations will not ban 2-stroke engines from use on local lakes, they will definitely restrict the sale and use of older engines. However, these new laws won’t affect boats sold on a private lake. They are still legal to use in California, but new buyers are encouraged to purchase energy-efficient systems.
Two-stroke outboards emit dangerous gases that affect the air, especially carbon monoxide. The emissions from these engines are similar to that produced by thirty to fifty four-stroke cars. In addition, about one-third of the fuel used in these engines is wasted in carburetors.
Possible ban on sale of two-stroke engines in the U.S.
California’s Assemblywoman Debra Bowen is pushing for a possible ban on the sale of two-stroke marine engines. The measure is a way to curb water pollution by the marine industry. Two-stroke engines emit more hydrocarbon pollutants than four-stroke engines. Two-stroke engines have a simple design, so fuel can pass through the exhaust pipe unburned. These unburned fuel particles can contribute to smog and water pollution.
Proponents say that a ban on the sale of two-stroke engines will improve the health of Californians. According to the California Air Resources Board, these engines are responsible for almost as much air pollution as light-duty passenger cars. In fact, 15 million of these engines emit about 141 tons of smog-forming emissions every day. Corey says that a ban on these engines would benefit Californians by improving air quality, especially in low-income communities of color.
The proposed regulations will also affect recreational marine engines, which are regulated by California’s Air Resources Board. ARB regulations require new vessel engines to meet clean-air emission standards. These regulations took effect in 2001 and 2004, and require manufacturers to build engines that meet these standards. However, they do not restrict the use of waterways.
Californians are not alone in wanting to ban two-stroke engines. Many cities, including San Francisco, have restrictions against personal watercraft. In fact, one city has banned the sale of two-stroke engines in San Francisco. A ban on two-stroke engines in California is expected to go into effect by 2035.
Two-stroke motorcycles were regarded as pioneers of modern motorcycling technology. These engines were powerful and compact, and they were relatively easy to maintain. Their low cost and adaptability led many riders to customize them to suit their needs. Two-stroke motorcycles have remained popular in many places, and have made their presence felt throughout history.
The California ban on two-stroke engines is just one of several steps in a string of government regulations aimed at cutting emissions. Other states may consider similar measures. However, there is still some shakiness around the proposed ban. The California Air Resources Board may decide to delay the implementation of the ban if it finds it is not feasible.
