Keep your Yanmar engine safely cooled with an Orbitrade raw water pump impeller. The impeller is a critical wear part that ensures stable water flow and thus efficient cooling – ideal for both daily operation and longer voyages.
The impeller drives the raw water pump and helps prevent overheating, reduced cooling performance, and costly consequential damage. Especially when dealing with saltwater, sand/particles, and high operating hours, regular replacement is simple and inexpensive insurance.
Orbitrade is a proven aftermarket alternative with fit and function that matches the engine's requirements. Typically, replace at least once per season or according to the manufacturer's recommended service interval to maintain optimal cooling and operational reliability.
