The Performance Vent System, designed and patented by Mercury marine, is a management system of the exhaust gases that exit from the propeller's tube allowing us to control the venting of the propeller blades in order to optimize the acceleration for quick planing.

It is nothing more than one or two holes located behind each blade, on the outer propeller’s hub, through which the exhaust gases are driven between the propeller blades.
