I just took my new boat out and hit some shallow water and broke a blade on my prop. It was a 15 x 17 Michigan Wheel and I'm just trying having a debate as to whether it will make a difference to save $20 and by a 15 x 17 Solas Amita to replace it with. A 15 x 17 Alum. prop is all the same right? Just wondering. And is it worth that $15 to get one of those prop wrenches to put them on and off? Or will a some normal socket or even some vice grips work as well? Just wondering. Thanks.<br /><br />Jeff
