A bought a scond hand Rapture prop and it appears the previous owner drilled the vent holes larger than original size. With current pitch (15") I dont need the extra slippage and want to plug the holes. Any ideas on how to do this? Epoxy?
Thanks for the tips guys. Another thought occered to me: drill them out to the size of Mercury's adjustable plugs and buy their snap in plugs. If the holes are already to large, I may have them welded or filled with Marine Tex or similar product.
