Have a 2004 Catalina 36 MK II being delivered to me in Miami. It lost it's prop and is now sitting in a marina waiting until tomorrow when I can order a new prop with overnight delivery. The delivery captain said in all of his years he never lost a prop. Boat was hauled as part of the purchase survey. It was found to be missing a pin at the nut. Yard claims they placed a pin in. Nevertheless, the boat lost a prop. As alternative I was thinking of using a prop from Perfect Pitch Propellers, an urethanse product. Anyone have experience or know of this product. Found it at www.performancepropellers.com
