   3 Blower system output (Fo) cubic feet per minute.

6. (c) Each exhaust blower system required by paragraph (a) (2) of this section must exhaust air from the boat at a rate which meets the requirements of Table A, Column 3, when the engine is not operating.
7. (d) Each intake duct for an exhaust blower must be in the lower one-third of the compartment and above the normal level of accumulated bilge water.
8. (e) More than one exhaust blower may be used in combination to meet the requirements of this section.

9. (f) Each boat that is required to have an exhaust blower must have a label that--

   1. (1) Is located as close as practicable to each ignition switch;
   2. (2) Is in plain view of the operator; and
   3. (3) Has at least the following information: WARNING--GASOLINE VAPORS CAN EXPLODE. BEFORE STARTING ENGINE, OPERATE BLOWER FOR 4 MINUTES AND CHECK ENGINE COMPARTMENT BILGE FOR GASOLINE VAPORS.
