For the past couple of years other independent engine builders have continued to build and sell new 500+ HP engines in violation of EPA and CARB regulations on the 'down-low'. Up until recently, enforcement has been very minimal, but that is changing and small engine builders are beginning to be checked and when they are found in violation the fines are hefty, so much so that they would likely put them out of business. Don't think for a minute that Mercury Racing isn't getting a premium price for that certification. If you buy a new boat with a non-emissions certified new engine, the buyer is likely to have an issue/problem when it comes time to register the vessel (more states are beginning to crack down at time of registration). Unless the engine is specifically designated for racing/competition only, it better have the low-emissions certification sticker and paperwork to go with it.
