| Hi,
Cannot easily say sight unseen. Universally you can bet on a bolt in the center securing it to the crank. It will also be keyed, usually 5/32" square stock. There may may also be set screw(s) holding it in place(again 5/32" Allen wrench to loosen if there.) Many manufacturers make some provision for pushing the impeller off, such as a threaded area underneath that bolt in the center. Got a model#?
Peace,
