## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product, but no match for a 2 year old!!
*by K***T on August 18, 2020*

Product works great and seems to hold up good under NORMAL use. A litle tight getting on & off due to the close fitting tolerances. But as I found out, they do not hold up well to the strength of a 2 year old amplified by hydraulics when she wants to drive grandpa's boat in the garage. Oh well lesson learned, new set ordered.

### ⭐⭐⭐⭐⭐ Fits and holds in place
*by J***. on July 22, 2025*

These fit perfectly without any modifications or adjustments on my Yamaha F150 with hydraulic Seastar steering. My motor used to float when bouncing from trailering over 2 hours each way to launch. Not anymore!

### ⭐⭐⭐⭐⭐ A must have for Outboard Trailering
*by A***R on April 4, 2023*

These are another great product from TH-Marine! The fit is great and they keep the outboard straight and solid when towing. I leave mine on when storing or trailering my boat. If you are on the fence, just buy them and you'll be glad you did.
