### ⭐⭐ 







  
  
    Mercruiser Raw Water Hose Ring Tool
  

*by R***F on Reviewed in the United States on August 11, 2017*

Not quite a good fit.  I had to grind down some to get the 'tabs' to fit into the hose ring.  Even then, not a good fit.  Disappointed yet all I had.  Prior one was plastic and broke.  This was metal and would not break but would not push into the hose rings as needed deep enough to get a good fit.  I purchased three different hose ring pairs (faster delivery, as this was a slow delivery item), including Mercruiser item and still had the issue of fit.

    Junk
  

*by D***N on Reviewed in the United States on October 6, 2018*

Doesn’t fit, useless for what it is intended. Notches do not fit into slots as they are intended. Not worth $30, not worth $6

### ⭐⭐⭐⭐ 







  
  
    Works but pricy
  

*by J***S on Reviewed in the United States on March 18, 2021*

Worked well just expensive.
