Recommended for you

The impeller of the seawater pump of Yanmar diesel engines is a wearing part that is recommended to be replaced periodically before the rubber hardens and crumbles — in the worst case, clogging the cooling system and causing the engine to overheat. The range includes Orbitrade brand genuine quality impellers for several Yanmar engine models with exact part numbers (for example 104211-42071, 124223-42092, 128176-42071, 129670-42531 and 128990-42200), so the right part can be found directly from the engine model plate or from the markings on the old impeller.

In addition to individual impellers, a seawater pump service kit (KIT) is available, which includes the impeller as well as seals and other wear parts at the same time — a practical choice when the pump is opened for service anyway. There is also a separate impeller service kit for the smaller 2GM, 3GM, 2YM15 and 3YM20/30 series engines, which covers the pump dimensions of these models.

It is recommended to inspect the impeller annually during winter maintenance and replace it at the latest when the blades start to show cracks or hardening — preventive replacement is always cheaper than damage caused by engine overheating. Since the rubber compound of the impeller ages even when not in use, it is a good idea to keep a spare impeller with you on longer sailing trips, especially with older engines.

It is not a good idea to extend the impeller replacement interval too long, even if the pump seems to be working perfectly — rubber hardening often occurs unnoticed, and the first sign of a problem may be a sudden increase in engine temperature while driving, at which point the damage has already occurred. The recommended replacement interval is typically 200–300 operating hours or once a season, whichever comes first, but long periods of non-use also age the rubber compound. When replacing, it is also a good idea to always check the inside of the pump housing for scratches and wear, as a worn housing can rub against a new impeller inefficiently or quickly. Orbitrade parts are manufactured to the dimensions of the original parts, so they fit directly without modification, but it is important to check the correct part number before ordering, as similar-looking Yanmar engine models can still use different impeller sizes depending on the generation. Purchasing a maintenance kit instead of a single impeller is often more cost-effective if the pump has to be opened anyway, because replacing the seals at the same time prevents future leaks.

Keeping a spare impeller with you on longer sailing trips is recommended, especially with older engines whose original pump is already several years old.

When ordering a part, it is always a good idea to compare both the engine model number and the old impeller's part number twice to be sure.
