## Customer Reviews

### ⭐⭐⭐⭐⭐ Just right for my Rev4 Props
*by J***3 on July 29, 2025*

Absolutely perfect. Worked great on my Rev 4 14.6x19 props for my 2020 v6 225 with 1" shaft. Easy install, fit perfect.

### ⭐⭐⭐⭐⭐ An inexpensive spare; an easy replacement.
*by R***S on August 6, 2024*

The hub kit is easy to install and the instructions are clear and easy. (Note that if you are replacing a hub kit on an existing prop you may need a hammer and some penetrating oil to remove the plastic bushing from the prop.).Also, be sure to get the tabs of the lock washer as tight to the flats of the prop nut as you can. I left a little “breathing room” and my prop began to loosen itself. My own lack of attention to detail was easily fixed, however.For the money I am happy to carry a spare so a prop mishap doesn’t end my day on the water.

### ⭐⭐⭐⭐⭐ Mercury Quality.
*by S***N on September 2, 2024*

This Quicksilver hub kit is the exact same hub kit as the Mercury brand. Mercury owns Quicksilver and the parts are identical in fit and quality. Quicksilver is usually less expensive. This particular product fits several motor models including my 2024 75hp 4 stroke.
