I have a stainless steel prop in the shop( got it from my brother in law) that got drug on the pavement enough to take off about a quarter of an inch of steel. The prop shop says $85.00 and he can fix it as good as new....balanced and ready to go. My question is: Does anyone know how a prop is actually balanced? and will it be obvious once the boat is run if it is out of balance? Thanks in advance.
