Reliable Marine Maintenance Starts with the JPR-S7632 JMP Marine Caterpillar Raw Water Pump

November 13, 2025

When it comes to marine maintenance, ensuring your vessel’s cooling system is operating at peak performance is non-negotiable. The JPR-S7632 JMP Marine Caterpillar Replacement Engine Cooling Raw Water Pump is engineered for professionals and boat owners who demand durability, compatibility, and dependable performance in every voyage.

Built to replace multiple Caterpillar OEM pumps — including part numbers 4P7168, 113-1109, 152-8392, 167-4252, 170-6116, and 353-7979 — the JPR-S7632 offers a 100% plug-and-play fit for Caterpillar 3116, 3126, 3126B, C7, and C9 engine models. Whether you’re upgrading or performing scheduled marine engine maintenance, this pump is designed to make the process smoother, safer, and more efficient.

Built for Marine Performance and Longevity

The JPR-S7632 uses the JMP 7608-01K impeller, specially designed to outperform similar models such as the Sherwood 27000. Unlike the Sherwood version, which can cause clearance and overheating issues, the JMP impeller is precision-machined to fit perfectly—eliminating risk of damage and ensuring optimal raw water flow for superior engine cooling.

Every detail of this pump reflects marine-grade engineering:

• Heavy-duty bronze casting for corrosion resistance in harsh saltwater environments

• 3X Series non-magnetic shaft for strength and reliability

• O-ring end cover packing and spline drive shaft for easy installation and long-term sealing integrity

• High-flow impeller and fast velocity chamber design for improved cooling efficiency
   

Whether you’re maintaining a commercial fleet or servicing a private yacht, this replacement pump provides the kind of reliability that reduces downtime and helps prevent costly overheating events — a key focus of any marine maintenance program.

Trusted Compatibility and Service Support

JMP Marine’s JPR-S7632 is a universal-type replacement compatible with Sherwood P1710, P1726, and P1732 series pumps. It’s internally upgraded for enhanced performance — with improvements to the impeller, wear plate, cam, mechanical seal, and shaft — ensuring longer life and better dependability than factory versions.

For continued performance, Major Service Kit JSK0072 and Minor Service Kit JSM0002 are available separately, giving marine technicians all the internal components they need for scheduled servicing and preventive maintenance.

Your Partner in Marine Maintenance

Regular marine maintenance is the key to extending the life of your engine — and the JPR-S7632 is built with that goal in mind. With plug-and-play installation, heavy-duty materials, and JMP’s trusted craftsmanship, this pump delivers lasting performance and peace of mind for every voyage.
