Patent attributes
A safety propeller for a boat motor includes an annular collar having a front opening, a rear opening and a continuous peripheral wall. A plurality of angled, horizontal slits are circumferentially positioned about the peripheral wall to allow water to pass through the collar. Both the front opening and rear opening each include a plurality of guard blades radially extending from a centrally disposed hub. Between the front and rear guard blades is a main propeller likewise including a plurality of blades radially extending from a centrally disposed hub. The collar, guard blades, main propeller, shaft and hubs are integrally connected to form a unitary structure. Accordingly, when the device is operably connected to a boat motor drive means, the guard blades and main propeller rotate in unison to propel a boat through water. The guard blades are positioned at a discrete angle and pitch so as to project animals, humans and objects away from the device.
