I have a 19‘ Sea Ray powered by a 190 hp Mercruiser Alpha I. I purchased a 14×21 prop to replace the existing aluminum prop which was slightly damaged by an underwater obstruction. The most impressive feature to me is the fact that if I hit an underwater obstruction, the blade(s) affected will break instead of destroying my stern drive unit. In fact, this past summer someone who didn‘t have much experience was trailering my boat and didn‘t raise the motor all of the way. The concrete ramp took off half of the skag and 2 blades from the prop, but the stern drive was not damaged. If I was using an aluminum prop, the stern drive would have been damaged and I would‘ve been without a boat the rest of the summer. I would‘ve also spent over $200 to buy more aluminum props and thousands to repair the stern drive. As you can see, I am very satisfied with your product.

I believe I have been using my Piranha Prop since 2001. I wouldn‘t use anything else. I fish and don‘t want a damaged prop ruining my day. I carry extra blades in the boat and I can change them on the water. I have a Carolina Skiff with a 90hp Merc. I use a 21 pitch, 3 blade. It will run 42 mph top speed. I drive it 32 mph most of the time. One friend of mine broke his lower unit with a stainless on a new 125 hp Merc and it cost him over $3000.00. I ordered him a 4 blade, 22 pitch Piranha. He is very happy.

I normally would not respond to a vendor‘s questions like this one, but I do have to say my new propeller made a world of difference in the performance of my boat. I just have a 1982 15‘ boat, with a 1992 Yamaha 90 hp. I do not remember the pitch and all that stuff, the recommended prop you guys suggested was perfect for my needs, and the fact that a second set of propellers came in the deal was great for me. Thanks.
