Have 2 on my 36v motor guide. Wouldn't fish in Florida without them. Soft weeds, will though, stack on your shaft and bog you down until cleared. For stiffer weeds like wire grass and pads it works great at full power or near so. I also raise the motor so prop is just under the surface. Minn Kota are better in the weeds. I would think it eould make them more so. Ninja blade uses 3m tape now to attach to the motor. I have had no issues after a year of use with the tape. Lost the first one that I epoxied on.
