Abstract
An apparatus and method for injecting a boat engine's exhaust gasses into the boat propeller's propwash, aft of the propeller. The apparatus comprises piping which injects the boat engine's exhaust gasses into the propwash of the boat, aft of the propeller. This results in the movement of the exhaust gasses away from the boat thus protecting the health of the boat occupants, reduced levels of air pollutants, and a reduction in noise pollution. The injection piping includes several features that protect the boat in the event that the injection piping should strike a solid object in the water.
