(A) Every gasoline engine installed in a motor boat after 4-25-1940, except outboard motors, shall be equipped with an acceptable means of backfire flame control.
(B) Installations made before 11-19-1952, need not meet the detailed requirements of this rule and may be continued in use as long as they are serviceable and in good condition. Replacements shall meet the applicable conditions in this rule.
(C) Installations consisting of backfire flame arresters bearing United States Coast Guard approval No. 162.015 may be continued in use as long as they are serviceable and in good condition. Replacements shall meet the applicable conditions of this rule.
(D) Installations consisting of engine air and fuel induction systems and given United States Coast Guard approval No. 162.015 may be continued in use as long as they are serviceable and in good condition. Replacements shall meet the applicable conditions of this rule.
(E) The following are acceptable means of backfire flame control for gasoline engines:
(1) A backfire flame arrester constructed in accordance with specifications of, and approved by, the United States Coast Guard. The flame arrester shall be suitably secured to the air intake with flame-tight connections;
(2) An engine air and fuel induction system which provides adequate protection from propagation of backfire flame to the atmosphere equivalent to that provided by an approved backfire flame arrester. A gasoline engine utilizing an air and fuel induction system, and operated without an approved backfire flame arrester shall have the installation tested and labeled in accordance with the specifications of, and approved by, the United States Coast Guard;
(3) Any attachment to the carburetor or location of the engine air induction system by means of which flames caused by engine backfire will be dispersed to the atmosphere outside the vessel in such a manner that the flames will not endanger the vessel, persons on board or nearby vessels and structures. All attachments shall be of metallic construction with flame-tight connections and firmly secured to withstand vibration, shock and engine backfire. The installations do not require formal approval and labeling, but will be accepted by state and local law enforcement officers on the basis of compliance with this rule; and
(4) Where manufacturers wish to produce vessels having an integrated engine-vessel design, a pre-market approval of an engine air induction system is available. An installation shall be tested and labeled in accordance with the specifications of, and approval by, the United States Coast Guard.
