## Customer Reviews

### ⭐⭐⭐⭐⭐ Replaced the OEM part, fit like a glove
*by C***E on July 6, 2021*

Nothing to dislike, ordered on Monday was in my hand by Wednesday. Everything you need to keep the cooling system going. Great replacement for the OEM part (Westerbeke 27A) Even bought an extra one a few days later.

### ⭐ Not a substitute for Westerbeke 034449 kit
*by D***L on October 29, 2023*

Gasket does not align with bolt holes. Is not a direct substitute for Westerbeke 034440 impeller kit.

### ⭐⭐⭐⭐⭐ Excellent seller.
*by C***N on December 27, 2021*

Quick, accurate, delivery in good condition.
