Abstract
A safety system associated with an engine of a marine vessel wherein the safety system includes a blower, a control unit, and a plurality of sensors. A vacuum sensor is coupled to the intake manifold of the engine of the vessel for the detection of pressure at the intake manifold. The vacuum sensor transmits a signal to the control unit, with the signal having a characteristic corresponding to the pressure at the intake manifold. Detection of a vacuum condition associated with engine idling or low cruise operation causes the control unit to activate the blower. The safety system includes interactive heat sensors and vapor sensors to monitor the atmosphere in an engine compartment. Detection of a volatile environment activates the blower and triggers both an audio and a visual warning.
