## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality product, fast delivery
*by D***Y on August 24, 2023*

Good price for OEM product. Delivery was as stated by the vendor. I would use this vendor again.

### ⭐⭐⭐⭐⭐ Mercury 60hp Bigfoot
*by R***  on June 17, 2024*

Works as should, good price for OEM and easy to install. Looked up a YouTube video to double check through the hub assembly directions and was extremely easy.

### ⭐⭐⭐⭐⭐ OEM always!
*by R***. on May 3, 2022*

I have never purchased an aftermarket propeller, so I can't say they are inferior. However, I am not willing to take the chance to save a few bucks. I think I would rather stay with OEM. This prop came in a bit of a battered box but the interior packaging was so well made that everything was perfect. Good instructions were included along with all the hardware. I am well satisfied with my purchase.
