Hi, I am new here. I don't own a boat, just doing a small project for school on material selection for boat propellors. <br /><br />I tried searching the web for prop failures (breakage and crack growth), where likely does failure occur on props. Had no luck. I would really appriciated if any of you guys know any websites which dicusses prop failures, where I can some photos and information on loads on certain props used in power(speed) boats.<br /><br />any help would be greatly appriciated
