Abstract
An ignition delay vapor expulsion module is provided for accessory use with a boat. When activated, the module energizes an accessory ventilating fan for a predetermined time period. After this time period the fan automatically stops and the ignition is enabled so that the operator can start the engine. By preventing the operator from activating the ignition either before or during the ventilation process, explosive fumes may be safely and completely ventilated. An electronic timer and latching relays are used to implement the timing/switching functions.
