Description

The Sherwood 27000K Impeller Kit is a complete raw water pump service kit designed to restore proper cooling system performance in marine engines equipped with Sherwood 27000 series pumps. This kit includes a precision-molded neoprene impeller along with sealing components to ensure reliable water flow and long service life.

The impeller is responsible for circulating seawater through the engine cooling system. Over time, the flexible vanes can wear, harden, or crack, reducing efficiency and increasing the risk of overheating. Replacing the impeller at recommended intervals ensures consistent cooling performance and helps protect your engine from damage.

This kit is widely used across Sherwood pump-equipped marine engines, making it a key maintenance item for dependable operation.

Parts Desk Insight

The 27000K is one of the most common mid-to-heavy-duty diesel impellers. If you’re working on a Cummins 6BTA or 6CTA with a Sherwood pump, this is usually the one—but always confirm spline count, because that’s where most mis-orders happen

Parts Desk Insight

Sherwood impellers are very size-specific—even within the same pump series. Always confirm shaft size and spline type, especially on 27000-series pumps, to avoid ordering the wrong kit
