### ⭐⭐⭐⭐⭐ FIXED ALL MY BOAT PROBLEMS
*by L***G on October 5, 2023*

I researched props and hydrofoils for quite some time. I have a Volvo 5.7L with a 19pitch prop. Have plenty of power, boat would just not plane out. Thought about messing with props, but chose to start with the XR4. Previous reviews of the XR3 scared me off with breakage problems. I contacted Stingray directly and found that they now have a lifetime warranty against breakage and free returns if it doesnt fix the problems. Easy 10minute install, and it works flawlessly. Boat planes out easily and lost no top end speed.

### ⭐⭐⭐⭐⭐ Easy installation with perfect fit on my Merc 150
*by A***R on September 26, 2023*

Fits perfect and easy to put on, but it’s a leap of faith to do the required small holes drilling through lower unit anti vent plate. My boat planes a bit quicker and will stay on plane at lower speeds which is the main reason why I got it for the slow cruises with the wife. Don’t use it top speed too much but the foil makes it more stable for sure.

### ⭐⭐⭐⭐⭐ Works as it should.
*by A***  on July 25, 2025*

Works great! Easy to install.
