Reliable Generator Cooling Starts with Proper Marine Maintenance and the JPR-WB10IP Cooling Pump

June 2, 2026

When it comes to marine maintenance, cooling system reliability plays a major role in protecting onboard generators and engines from overheating and unexpected downtime. A dependable raw water pedestal pump helps maintain proper seawater circulation, ensuring your generator systems continue operating efficiently in demanding marine conditions.

The JPR-WB10IP JMP Marine Westerbeke Replacement Engine Cooling Raw Water Pedestal Pump is designed to provide consistent cooling performance for a wide range of Westerbeke and Universal generator applications. Whether you’re replacing an aging OEM pump or performing preventive marine maintenance, the JPR-WB10IP offers a durable, direct-fit solution engineered for long-term reliability.

Designed as a replacement for Westerbeke pump part numbers 55624 and 055624—as well as older part numbers 42026, 042026, 46120, and 046120—this compact pedestal pump also replaces Johnson pump models 10-24569-03 and 10-24569-09. Its universal-style design makes installation simple across many popular generator systems.

Engineered for Marine Performance & Durability

Every component of the JPR-WB10IP is built with real-world marine maintenance needs in mind. Constructed using a strong bronze body with heavy-duty marine-grade casting, the pump delivers excellent corrosion resistance and long-lasting durability in both saltwater and freshwater environments.

Additional performance features include:

• Marine-grade 3X series non-magnetic shaft for enhanced wear resistance
• Long-life mechanical seal to help prevent leaks and maintain cooling efficiency
• High-performance flexible impeller (JMP 7000-01K) for dependable seawater circulation
• Simple and compact design for easier installation and servicing

Weighing approximately 2.25 lbs (1.05 kg), the JPR-WB10IP is compact enough for tight engine room installations while still providing the durability required for continuous marine operation.

Designed for Preventive Marine Maintenance

Effective marine maintenance focuses on preventing failures before they happen. The JPR-WB10IP supports that approach with easy access to spare parts and simplified servicing procedures.

The pump is compatible with:

• Major Service Kit (JSK0165) – includes all internal replacement components
• Minor Service Kit (JSM0165) – ideal for routine maintenance and impeller servicing

While the pump is not internally interchangeable with OEM components, JMP Marine has incorporated internal design improvements to enhance quality, durability, and overall performance compared to genuine factory pumps.

Reliable Cooling for Westerbeke & Universal Generator Systems

The JPR-WB10IP is used across a large range of Westerbeke and Universal generator systems, including BCG, BEG, MCG, SBCG, and SBEG series models. Its universal compatibility and dependable cooling performance make it a practical choice for marine technicians and boat owners focused on improving long-term reliability.

By incorporating a high-quality cooling pedestal pump into your regular marine maintenance routine, you can help reduce downtime, protect generator performance, and extend equipment life.
