So my prop is pretty beat up. Im going to buy a new aluminum prop, I'm looking at the solas props on here. Do i need anything besides just the prop? Im thinking about the 14.5- 17 pitch 4 blade. If its too small when i get more power i can always use it for high elevation prop. http://boatpropellers.iboats.com/OM...-145-17_Propeller/796/6508/?cart_id=667865917
