Review: Perfect fit, nice quality. - I bought this set to replace my prop. Everything was a perfect fit, no issues. I bought a second set and zip tied it to my prop wrench in case I need to switch to my spare prop. Cheap piece of mind if you had to change out props in the water. you know your gonna drop something.....
Review: Good quality - Item was good quality however did not fit my Volvo penta 5 Liter engine

### ⭐⭐⭐⭐⭐ Good quality

Item was good quality however did not fit my Volvo penta 5 Liter engine

### ⭐⭐⭐⭐ Worked well
*by B***R on April 15, 2022*

Part came as advertised, easy install, direct fit when I swapped out my aluminum propeller to a stainless steel propeller on a 2001 volvo penta 5.0 GL with SX cobra outdrive. I did find out that i needed a thicker thrust washer on the prop shaft for my stainless propeller to keep it from rubbing the outdrive housing, which is a completely different part than this.
