Abstract
A method for the efficiency-increasing discharging of exhaust gases of internal combustion engines of boats into the water surrounding the boats is disclosed. The exhaust gases and a flow of water drawn from the surrounding water are mixed together in a low air pressure field, the low pressure of the low pressure field being produced by a reduction in the cross-section of the flow of water before mixing ensues.
