## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Good product
  

*by T***N on Reviewed in Canada on 18 June 2023*

Fit my boat motor great, very easy to put on…Thank you 😀

### ⭐⭐⭐⭐⭐ 







  
  
    Should have fitted one years ago
  

*by K***N on Reviewed in the United Kingdom on 4 October 2023*

This makes such a huge difference to boat performance, easy to install, it keeps the nose down and the boat planes really well at lower speeds it also stabilises the boat at speed

### ⭐⭐⭐⭐⭐ 







  
  
    Great for the value. Very easy to install.
  

*by B***. on Reviewed in the United States on 20 August 2020*

Easy installation. Very well worth the money. It does everything exactly what was supposed to do. It reduces the bow of the boat getting a faster response time to plane on top speed, does get a noticeable difference of greater gas consumption reduced to a fuel increase- leading to fewer gas trips. The biggest difference between having this versus not having it is how much more smoothly the ride is on top speed, with very little usage of the trim in addition to the planning.To install it takes less than an hour. Very easy to install yourself. Take it out of the box and place it where it should be, make sure measure twice to drill once. Drill the holes with the fins on it, as it has pre-drilled holes to guide it. Place the nuts and bolts on, tighten it snug, but not to over tighten it.Depends on the make and model lower unit to install it really doesn't take long to get it done. I had to remove the prop on my 140 HP I/O. Looks great and does an amazing job for my boat. Great for water tubers and skier's that appreciate it for a faster out of the hole experience.I highly recommend it. Worth every single penny, does pay for itself.
