The Stationary Repeller consists of a refined intake grate with sharpened tines and a sharpened base plate that act as a cutter. Being made of stainless steel, it is rugged and reliable. The intake grate can be engineered to fit any size watercraft — from personal watercraft to large yachts and military vessels. Once in place, as weeds or debris pass over the grate, the sharpened tines cut them; the smaller pieces are then able to fall away or flow through the impeller without affecting performance. The Stationary Repeller is also a modular design — if a tine is damaged, the tines can be replaced.
