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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/22897182-scp-34440-impeller-kit-replaces-westerbeke-34440-sierra-23-3307](https://www.desertcart.tn/products/22897182-scp-34440-impeller-kit-replaces-westerbeke-34440-sierra-23-3307) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-28*
