## Customer Reviews

### ⭐⭐⭐⭐⭐ Value for money is great..
*by R***Y on December 10, 2019*

Value for money is great.. Does the job and you do not have to save the old pins (you have plenty to use)...

### ⭐⭐⭐⭐⭐ Heavy duty pin fit perfectly on my Yamaha outboard.
*by M***H on May 14, 2021*

I have a new Yamaha F70 4 stroke and these cotter pins are heavier duty than the original pin on the castle nut. It still fit in easily when I greased the prop on the 20 hour service, but was a little longer and thicker than the Yamaha OEM, which is good. I am comfortable that my prop is staying put.

### ⭐⭐⭐⭐ Worked good
*by A***R on June 23, 2021*

Got it quickly
