Hey guys, I have a Triton 21 Patriot. In May of this year I started running a Mercury Fury 25p 4 blade which was, what I thought to be, an excellent purchase. The hole shot and handling was great with this prop. I had the prop on the boat about a month before it threw a blade. So I went to a Mercury Certified dealer and completed a claim and I'm assuming they returned the prop. I then received a replacement prop. So today, I decided to install the the new prop and go fishing today. I ran the boat on plane for about two miles when it threw another blade. Is this a problem with the manufacturing of this prop? Is this normal for the four blade props? Are there other four blade props that doesn't throw blades? The money and time I have in just getting this prop replaced seems to make running this prop not worth the trouble.
