Gori
Hello Steve,
I'm quite familiar with the Gori propeller as I work at Rigworks, Inc. here in San Diego and we carry them. All in all, they are awesome propellers. Gori manufactures a 1, 2 and 3 blade prop. The 1 blade design is ideal for minimal drag although the 2 blade design actually reduces drag by 35% when compared to a standard prop. A huge advantage that the 3-blade prop has is it's overdrive function. You can control the pitch and profile by regulating your boat's shift's and throttle control. This gives you same boat speed at lower RPM's. Also vibrates the boat less.To set it in overdrive all you have to do is put the boat in reverse until you start actually going backwards, set it to ahead again and boom there ya go.
Hope this helped,
Riley
