Kiwi prop --- feathering
We installed a Kiwiprop on our new (to us)Ericson 39B about a month ago. We are quite pleased with it. Seems well made and is simple to adjust the degree of pitch. Auto rotation of the prop was completely eliminated. That was actually the number one reason that made us want to get a feathering prop. Our transmission would not lock the shaft in place when the engine was off. Power in reverse was substantially improved over the original fixed three blade prop. We have not really had the boat long enough to get a fair sense of how much speed we gained under sail, but I would guess it is a half knot or so in lighter conditions. The price was definitely right, and they included a spare blade at no extra charge. Delivery was within a week of placing an order. I believe the cost was $1,250 including air shipment from Kiwiland.
