There is a rear guard section having two guard plates positioned adjacent to one another and extending outwardly and upwardly at a moderate slant from a center axis. The deflecting propeller guard is positioned with the guard section below the propeller and the deflecting section forwardly of the propeller. A center mounting plate is provided to be positioned adjacent to, and connected to the skeg of the motor assembly.
