Sherwood Pump

<h3>Sherwood Pump: The Marine Industry&apos;s Trusted Cooling Solution</h3><p><strong>Sherwood Pump</strong> has earned its place as one of the most respected names in marine fluid management. With roots stretching back more than a century — tracing to a copper and brass plumbing business co-founded by William Sherwood and David Buick — the brand has evolved from a modest workshop operation into a globally recognized manufacturer now operating under the Pentair family of brands. Today, Sherwood&apos;s reputation rests on a simple but vital promise: keep your engine cool, no matter what the water throws at it.</p><h3>OEM Trust, Built Over Decades</h3><p>What sets Sherwood apart from the competition is the confidence the world&apos;s top marine engine builders have placed in its products. Sherwood is recognized as an OEM provider for many leading marine engine manufacturers, meaning its pumps are engineered and tested to the exact specifications demanded by engine designers — not just reverse-engineered aftermarket alternatives. That original-equipment pedigree translates directly to reliability on the water.</p><p>At the heart of Sherwood&apos;s lineup are its <a href="/7562-sherwood-pump-water-pump-components-201276">Water Pump &amp; Components</a>, which represent the brand&apos;s broadest and most comprehensive product family. From complete raw water pump assemblies to individual rebuild components, these products are crafted to deliver high-volume water flow and dependable performance across a wide range of vessel types and engine configurations.</p><h3>Engine Cooling, From Pump to Impeller</h3><p>Sherwood&apos;s <a href="/7562-sherwood-pump-engine-cooling-pumps-accessories-200368">Engine Cooling Pumps &amp; Accessories</a> form the backbone of the brand&apos;s catalog. Raw water cooling is the lifeblood of any inboard marine engine, and Sherwood&apos;s pumps are engineered to maintain precise, consistent water flow under the demanding conditions of continuous engine operation. The brand offers pumps accommodating a wide variety of flow requirements, drive mechanisms, inlet restrictions, pressures, and port sizes — making it straightforward to find the right match for virtually any engine application.</p><p>For boaters sourcing a direct factory-equivalent replacement, Sherwood&apos;s <a href="/7562-sherwood-pump-engine-water-pump-2208">Engine Water Pumps</a> are designed and tested specifically for their intended engine applications, helping to maintain engine warranty compliance while delivering the durability expected from an OEM-specified part.</p><p>No cooling pump discussion is complete without addressing the rubber <a href="/7562-sherwood-pump-impellers-200573">Impellers</a> that drive water through the system. Sherwood&apos;s neoprene impellers are available in multiple series — including the well-known G Series and P Series lines — and are engineered to flex and recover reliably under continuous use. Keeping a fresh impeller on hand is one of the smartest preventive maintenance steps any boater can take.</p><p>Rounding out the catalog, Sherwood&apos;s <a href="/7562-sherwood-pump-flexible-impeller-engine-driven-pumps-impellers-parts-200425">Flexible Impeller Engine Driven Pumps, Impellers &amp; Parts</a> extend the brand&apos;s expertise to a broader range of flexible-impeller pump applications, including rebuild kits, wear plates, cam liners, and cover gaskets — everything needed to service a pump rather than replace it outright.</p><h3>Built for the Marine Environment</h3><p>Sherwood pumps are engineered with the harsh realities of the marine environment in mind. Non-corrosive bronze housings, precision-machined wear surfaces, and readily available repair kits mean that a Sherwood pump is not just a component — it&apos;s a long-term investment in the health of your vessel&apos;s engine. Whether you&apos;re sourcing a complete pump assembly, a set of replacement impellers, or a minor repair kit for a scheduled service, Sherwood&apos;s catalog covers the full spectrum of marine cooling pump needs.</p>

Product Details

The Sherwood Pump 12665-SHW is a comprehensive major repair kit designed to fully rebuild a wide range of Sherwood marine raw water pumps. This kit supplies virtually all internal components needed to restore pump performance, making it the ideal solution for a thorough overhaul rather than a basic impeller swap.

Kit Includes:

  • Impeller (1-1/4")
  • 2 Bearings
  • Mechanical Seal
  • Wear Plate
  • Cam
  • Cam Screw & Cam Screw Washer
  • Gasket
  • O-Ring
  • 5 Snap Rings / Retaining Rings
  • Key
  • Washer

Compatible Sherwood Pump Models:

  • G-9901, G-9902, G-9903

  • G30-2, G30-2B, G95-1
  • H10, J70, K75, K75B

This kit also replaces Sherwood part numbers 12400 and 13966. Cross-reference part numbers include 762-12665 and SHE 12665. For a minor repair, see Sherwood kit #23979, which covers impeller, seal, and O-ring only for these same pump models.

Keeping a major repair kit on board or in your service inventory ensures you can restore full cooling flow quickly, protecting your inboard engine from overheating. Always refer to the Sherwood G-series technical manual for torque specs and step-by-step rebuild procedures.

Came quick, no hassle

The item I bought was one to replace something I thought I had accidentally thrown away. A couple days after the boatplicity item arrived I located the like item I already had. I initiated the return process with boatplicity, as I no longer had need of the item. I completed the return request stuff and it said I would be contacted to continue the process but no one has contacted me.

The online purchasing system is very efficient. I had an issue with the delivery times, and the company quickly corrected the situation to my satisfaction.

I'm waiting on my refund. I was not happy that I couldn't talk to a real person regarding my return and my repurchase of the correct prop that I needed. So , if I get my total refund without a huge restocking fee(since the prop is new in original packaging and I bought another prop that is the correct size) then I will be extremely satisfied.

Great pricing and super fast service!! Thank you!

I received exactly what I ordered and shipping was on time

Convenient

Product delivered as expected and in perfect condition.
