I'm not sure I understand the question. Of course you can replace it if it has worn out. We do sell the replacement one as you saw per the link. The propeller does move the water at a much greater rate than an impeller. The specs regarding flow rates will be available soon on our site. For the 1200, it moves 295 GPH when the impeller is installed and 1300 GPH when the propeller is used. Max head is 6.0'.
