JMP Marine JSK0075 Volvo Penta D16 Engine Cooling Seawater Pump Major Service Kit
When a seawater pump on a Volvo Penta D16 starts weeping at the seal or the shaft develops play, replacing the impeller alone rarely solves it. The JMP Marine JSK0075 is the full teardown kit for that job. It carries the shaft, the two bearings, the mechanical seal set, the flexible impeller, the wear plate, the end cover, the o-rings and the assortment of hardware needed to bring a worn pump back to as-new tolerances instead of patching around the symptom.
The kit is built for the JMP JPR-VP0160D pump and for the Volvo Penta OEM units it replaces, part numbers 22905155 and 3589104. Engine coverage spans the D16C family, including the D16C-A MG, D16C-A MH, D16C-B MH and D16C-C MH. Before ordering, it is worth confirming the internal configuration of the pump on the engine, since JMP publishes compatibility notes covering which OEM genuine pumps share the same internals.
Every component is produced to JMP's own material standards rather than sourced as a generic replacement, which is why the impeller, seal and bearing set tend to hold up through a full season of hard running. For a vessel that depends on uninterrupted heat exchanger cooling, keeping one of these kits aboard turns an unexpected pump failure into an afternoon of work rather than a haul-out and a wait for parts.

Frequently Asked Questions
Q: Does this kit include the pump body or housing?
A: No. The JSK0075 supplies the internal wear components, shaft, seal, bearings and cover plate. The existing pump casting is reused, so the housing must be free of cracks, corrosion pitting and elongated bearing bores before rebuilding.
Q: Can I use this kit on a genuine Volvo Penta pump rather than the JMP unit?
A: In most cases yes, since the kit is dimensioned for Volvo Penta 22905155 and 3589104. JMP advises checking the internal configuration of your specific pump first, as production changes can alter which internals fit.
Q: How often should the full kit be installed instead of just an impeller?
A: Impellers are typically changed annually or every 200 to 300 operating hours. A full major service is warranted when the shaft shows play, the weep hole drips, the bearings feel rough, or the wear plate and cover show scoring.
Q: Do I need special tools to complete the rebuild?
A: A bearing press or arbor press and snap ring pliers are the main requirements, plus a means of pressing the mechanical seal squarely into its bore. The shims included in the kit are used to set shaft endplay during reassembly.
Q: Will the new impeller need lubrication at startup?
A: Yes. Coat the impeller with a marine-safe glycerin or impeller lubricant before installation and confirm raw water reaches the pump on first start, since running a flexible impeller dry for even a short period will damage the vanes.
