## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by S***T on August 2, 2025*

Exactly what I was looking for

### ⭐⭐⭐⭐⭐ High quality product at a much more reasonable price than the Mercury name brand.
*by J***E on May 10, 2024*

A week before launching our boat I noticed the outdrive lube was a little low. Having this delivered so quickly and being able to get it at such a better price than the Mercury brand was really nice.

### ⭐⭐⭐⭐⭐ What I needed!
*by D***R on July 7, 2025*

Was what I needed for Mercruiser outdrive. Order 2 though. It takes more than a quart.
