Sherwood G8005 Seawater Pump for Kohler GM63535 Generators
The Sherwood G8005 seawater pump is a high-performance marine raw water pump designed for reliable engine cooling in Kohler marine generators. Built with a corrosion-resistant bronze housing and stainless steel shaft, this pump is engineered to withstand harsh saltwater environments while delivering dependable cooling water flow.
This flexible-impeller pump replaces Kohler part number GM63535 and is commonly used on several Kohler marine generator models. Its self-priming design ensures fast water pickup, even at low engine speeds, making it ideal for marine engine cooling systems where dependable circulation is critical.
The pump uses a durable neoprene flexible impeller, allowing it to pump seawater, freshwater, and compatible cooling liquids smoothly with minimal pulsation. With only one primary moving component-the impeller-the pump design is simple, efficient, and easy to service.
Whether you are replacing a worn pump on a generator set or performing preventative maintenance on a marine engine cooling system, the Sherwood G8005 provides a direct-fit, marine-grade solution trusted across the boating industry.

FAQ
What does the Sherwood G8005 pump do?
The Sherwood G8005 is a raw water pump that circulates seawater through the marine engine or generator cooling system to prevent overheating.
What impeller does the Sherwood G8005 use?
The pump commonly uses the Sherwood 8000K impeller kit, which includes the neoprene flexible impeller and related service components.
Is the Sherwood G8005 self-priming?
Yes. The flexible impeller design allows the pump to self-prime and draw water into the cooling system once the impeller is lubricated by liquid.
What happens if the pump runs dry?
Running the pump without water can damage the neoprene impeller quickly. The pump should always be primed during initial startup to prevent impeller wear.
Is this pump serviceable?
Yes. Replacement impellers, minor repair kits, and major rebuild kits are available so the pump can be rebuilt instead of replaced.
