## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Fit pump housing and pumps housing
  

*by D***. on Reviewed in the United States on 1 July 2014*

Fit my '69 Johnson 6hp perfectly. Can be a bit tricky, like other impellers, to get into the pump housing. I used a little dishwashing detergent to slicken things up a bit. Pumps water the way it should. Nice strong stream from the tell-tale. No issues.

Works and fit perfectly!
