### ⭐⭐⭐⭐⭐ Easy to use and store.
*by D***N on July 23, 2019*

This is a heavy duty bracket that fits my Mercury 250 Pro XS. Simple to use and easily stores in a compartment when not in use. It also centers the motor and holds it in position when trailering.

### ⭐⭐⭐⭐⭐ It works great. Only takes a few seconds to apply and ...
*by M***E on January 31, 2018*

I have a Merc Pro Xl 250 on a Ranger Z521 and the transom support brace broke in half on my way to the lake and I had to replace it. After shopping for a replacement I came across this Atwood transom brace and decided to give it a try. It works great. Only takes a few seconds to apply and fits in a storage compartment instead of dragging the old style to the back of my truck.

### ⭐⭐⭐⭐⭐ Easy to use ,small storage, supports motor when trailering very well !
*by B***. on November 3, 2020*

A little pricey, but a very good product. I use it on a 225 HP Mercury
