## Customer Reviews

### ⭐⭐⭐⭐⭐ How practical, simple and safe it is and how well they have improved it.
*by R***Z on April 10, 2025*

It seems to me a good product for what it was designed for, it also has the option in the future if you want to easily fit an engine with an interior that they sell on Amazon to use automatically to each person's taste or paying less than if you buy it already with everything, I have not mounted it yet because it is a project but soon I will transmit my experience but my expectation is the best, I will use it with a Mercury 20 HP manual 20" leg, in addition the seller is very accessible for any help and very cordial

### ⭐⭐⭐⭐⭐ Follow instructions
