Yes, an outboard engine typically requires a backfire flame arrestor. This safety device is designed to prevent flames from escaping the engine's air intake, which can occur during backfire events. While not all outboard engines may have this requirement, it's essential for those that operate in environments where flammable vapors are present, such as in boating. Always consult the manufacturer's guidelines and local regulations to ensure compliance.
