Ventilation is the systematic removal of smoke from a building. Ventilation is usually accomplished with one of two methods: positive and negative pressure ventilation. Positive pressure ventilation increases the atmospheric pressure in the building until it is grater than the pressure outside the building. With negative pressure ventilation, the pressure inside the building is reduced until its less than the pressure outside the building.

Ventilation is a situation where surface air or exhaust gasses are drawn into the propeller blades. When this situation occurs, boat speed is lost and engine RPM climbs rapidly. This can result from excessively tight cornering, a motor that is mounted very high on the transom, or by over-trimming the engine.
