### ⭐⭐⭐⭐⭐ 







  
  
    Just what I needed.

Good match for my boat engine. What I needed.

### ⭐⭐⭐⭐⭐ 







  
  
    cured my overheating problem
  

*by L***T on Reviewed in the United States on 19 July 2019*

after changing out the thermostadt, engine was still overheating erratically...changed this impeller and no more overheating issues

### ⭐ 







  
  
    Rigidity issue
  

*by C***M on Reviewed in the United States on 27 June 2022*

This was a hard lesson to learn. This impeller looked correct and fit perfectly in a volvo 4.3L I/O. Only after weeks of overheating on trial runs, downtime and replacing every other element of the cooling system, I turned to the dealership, which was able to determine that the fins were far too soft to move raw water as they needed to. After they pinpointed the problem, they showed me the difference in rigidity of the fins on this impeller vs. OE volvo. Wow. Really disappointing.
