Every year personal watercraft are more powerful and efficient on the water. Even with the modern design of today's hulls, there is still much room for improvement. One way to upgrade the handling of your Yamaha watercraft is to bolt on a Pro-Tec Moflow intake grate. Our Moflow intake grates evenly flow water from the front and back of the intake tract to keep your pump loaded in the roughest water conditions with no loss of top speed in smooth water. Cast from aluminum and powder coated for a smooth professional finish.
