Performance Product Use & Compliance Notice

Atlantic Jet Sports supplies high‑performance components engineered solely for closed‑course racing and sanctioned competition. These parts are not designed, tested, certified, or warranted for use on public waterways or on watercraft equipped with emissions‑controlled systems.

Installing or using these components may change the watercraft’s safety characteristics, emissions compliance, or legal classification. Using competition‑only products on public waterways may violate federal, state, or local regulations.

By purchasing, installing, or operating a watercraft equipped with these components, the user acknowledges and accepts full responsibility for all associated risks—including, but not limited to, personal injury, property damage, mechanical failure, or legal consequences. The user further agrees that Atlantic Jet Sports assumes no liability for damages arising from improper installation, misuse, or operation outside of competition environments.

Product Installation Disclaimer

⚠️ Warning — Professional Installation Required

• Ensure the hull is fully ventilated and free of fuel vapors before using electric or battery‑powered tools. Failure to do so may result in fire, explosion, serious injury, or death.
• Disconnect the battery before performing any installation or maintenance to prevent accidental ignition, electrical shock, or unintended engine engagement.
• Allow the engine, exhaust, and surrounding components to cool completely before beginning work.
• No smoking, open flames, or spark‑producing devices should be present during installation.

This product is not intended for use on watercraft equipped with pollution‑control systems. Modifying or removing emissions‑related components may violate state or local laws and may render the watercraft illegal for use outside of competition.
