| Message: | The propeller made of copper have less rotating mass than other materials, which equates to faster acceleration. It is much more effective propeller that drives to boat through the water with less power . The copper material blades are also machined with a much better-designed cup in the blade. The cupping of the blade allows the propeller to hold more water on the blade`s surface with high performance. url:http://www.jerimarine.com |
