No, a backfire is the ignition of unburnt fumes in the exhaust system.
Ignition control device
If your pleasure craft has a car or truck engine converted for marine use, it must have a marine ignition system designed to prevent the ignition of gasoline fumes. This typically includes features such as a flame arrestor, which prevents any backfire from igniting vapors, and ignition components that are sealed or designed to reduce the risk of sparks. Additionally, proper ventilation must be ensured in the engine compartment to disperse any accumulated fumes safely.

A 'spark ignition ' engine is your regular gasoline engine as opposed to a diesel, which is a 'compression ignition' engine
When an inboard engine backfires, several mechanisms can prevent the ignition of gasoline fumes. First, the engine's design typically includes a flame arrestor or backfire trap, which helps extinguish flames before they can ignite fuel vapors. Additionally, proper ventilation in the engine compartment disperses fumes, reducing the likelihood of ignition. Regular maintenance and tuning of the engine also ensure optimal performance, minimizing the risk of backfires.
To prevent the ignition of gasoline fumes during an engine backfire, several measures can be implemented. These include ensuring the engine is properly tuned and maintained to minimize backfire occurrences, using a well-designed exhaust system that reduces the chances of flames reaching the fuel vapors, and employing flame arrestors in the intake and exhaust systems. Additionally, proper ventilation in areas where gasoline is used can help disperse fumes and decrease the risk of ignition.
most watercraft are required by law to be outfitted with a USCG approved intake spark/flame arrestor.
Mixing Carbon Dioxide (fills fire extinguishers) with Gasoline will prevent ignition. So nothing
Compression ignition is deisel. Otherwise, spark ignition is gasoline.
