A backfire flame arrestor is typically required for gasoline engines in boats, particularly those using carburetors. This safety device helps prevent flames from escaping the engine compartment in the event of a backfire, which can be particularly dangerous in enclosed spaces. The U.S. Coast Guard mandates flame arrestors on certain types of boats to enhance safety and reduce fire hazards. Diesel engines, on the other hand, generally do not require flame arrestors due to their different combustion process.
