Developments in 2-Stroke Engine Manufacturing

Recent developments in the manufacturing of 2-stroke engines reflect an adaptation to environmental concerns. For instance, the Hirth line of small engines from Germany remains mechanically unchanged in 2023, but there’s a shift in sales and service management in the US.

These engines, offered with various options like different gear ratios and electronic fuel injection, adapt to modern environmental standards. However, costs and shipping have become challenging aspects, with shipping costs nearly tripling. Rotax, another major player, discontinued all 2-stroke engines except the 582 UL, which remains in stock and available for purchase in 2024​​.

Federal and State Regulations Update

There have been significant updates in US federal and state regulations regarding 2 stroke engines. A notable point is the ban on the sale of new carbureted 2-stroke engines in California, which was adopted as a state law from a federal law. This ban aims to accelerate the reduction in air pollution.

Moreover, California implemented this federal law earlier than required, demonstrating a proactive approach toward environmental protection. The rest of the US followed suit, prohibiting the sale of new carbureted 2-strokes since 2008. Additionally, California implemented more stringent emission limits for outboard engines, surpassing federal standards​​.

Environmental Policies and the Future of 2 Stroke Engines

In 2022, the US made significant advances in environmental regulations, such as the Inflation Reduction Act, which allocated $369 billion towards climate-change endeavors. California introduced several new environmental measures, including a ban on gasoline-powered cars from 2035 and enhanced wildfire protection programs.

These advancements indicate a growing focus on reducing emissions and promoting sustainable alternatives, which could impact the future use and regulation of 2-stroke engines​​.

EPA’s Planned Regulations for 2023

The US EPA announced plans to implement tougher greenhouse gas emissions rules for heavy-duty vehicles through at least 2030. These new standards, expected to be finalized by the end of 2023, aim to significantly reduce carbon dioxide emissions from heavy-duty vehicles.

This move aligns with the global effort to reduce greenhouse gas emissions and could potentially influence the regulations surrounding 2 stroke engines​​.

Can You Still Buy 2-Stroke Outboards In The United States?

Yes, you can still purchase traditional two-stroke outboard motors in the United States, although their availability is becoming limited. Companies like Mercury Marine and Yamaha continue to offer two-stroke outboards, especially outside California where stricter regulations are in place.

BRP, the parent company of Evinrude, remains dedicated to the development of 2-stroke outboard motors, as evidenced by their new series of Evinrude outboards featuring E-TEC G2 direct injection technology.

However, it’s important to note that some manufacturers, like Yamaha and Mercury, have ceased the production of direct injection 2-stroke outboards, shifting their focus to the latest generation 4-strokes which offer comparable weight and advanced digital features​​​​​​​​.

Are 2-Stroke Boat Motors Legal In Colorado?

In Colorado, particularly on the Colorado River lakes like Powell, Mead, and Mohave, there is a ban on personal watercraft (PWCs) with carbureted two-stroke engines.

This regulation, enforced by the National Park Service, aligns with the 2006 emission standards set by the Environmental Protection Agency (EPA) for two-stroke engines. Boats and PWCs meeting these standards through direct-injection two-stroke or four-stroke engines are exempt from this restriction.

Moreover, there are plans to extend the ban to all two-stroke engines that do not meet the 2006 EPA emission standards. However, in some other areas managed by different federal, state, or local agencies along the Colorado River, two-stroke PWCs may still be allowed, so it’s advised to check local regulations before visiting any specific area​​​​​​.

Are Two-Stroke Boat Motors Banned In Any States?

As of current regulations, no US state has implemented an outright ban on all two-stroke boat motors. However, several states have adopted strict regulations and restrictions, particularly on older two-stroke engines that fail to meet modern emission standards.

California, for instance, has stringent regulations on two-stroke engines. This trend towards stricter environmental regulations has resulted in localized restrictions and a general reduction in the use of older, more polluting two-stroke engines.

For example, the National Park Service has implemented a rule to prohibit carbureted two-stroke engines on certain lakes due to their negative environmental impact, particularly where these lakes supply drinking water, like Lake Mead in Nevada​​​​​​​​.

Conclusion

To conclude, Where Are 2 Stroke Engines Banned In The US? While there are no sweeping state-wide bans, the trend is clear. Regions across the US are increasingly restricting or banning 2 stroke engines to protect the environment.
