Fyi to those interested in a Hustler prop. I have one on my sig boat now purchased a year and a half ago but dinged it at the end of last season. I ordered a new one on line and was assured my current round Turning Point hub would fit the new Turning Point Prop. Well long story short the prop arrived and Turning Point changed their hub system to a new square design rendering my nearly new hub useless. I left a message for the website to call me to discuss why they sent me a prop requiring a square hub when I previously verified on the phone that the round hub would fit and they amazingly didn't call but overnighted a second identical, square hub prop. I called again and they realized the round hub prop was just discontinued and they had run out of stock. I am now forced to buy a square hub for $40 to fit the new prop and I now have two new props, charged for both plus shipping. Basically the site, not iBoats, isn't interested in making anything right. In any event just know that Turning Point changed their hub design to fit other brands hub requirements completely ignoring the current prop owners.
