Impeller size & cross-reference charts
The complete tables — Sherwood (14), Johnson Pump (25) and Jabsco (75) — with dimensions in metric and imperial, drive types, materials and the published cross-references between brands — including the Volvo Penta, Yanmar, Onan, Cummins and Perkins OEM numbers they replace. Use find-in-page for any part number you're holding.
Sherwood
Thru-key and threaded-insert impellers for Sherwood raw water pumps — note "threaded" describes the puller insert, not the shaft drive (the 26000/27000 are spline drive).

Figures are the manufacturers' published dimensions; known printing errors in older charts have been corrected against current factory tables. Cross-brand equivalents fit the same pump but may differ in blade count. If a number you have doesn't appear, it may be an OEM or aftermarket alias — the finder searches those, or send it to us.
Chart FAQs
Are these the same charts the old PDFs had?
Same sources, better data. These tables come from the Sherwood size chart, Johnson's IB-506 identification guide and the Jabsco replacement guide that Luxfords supplied for years — checked against the manufacturers' current tables, with the handful of printing errors in the old PDFs corrected and documented. And unlike a PDF, they're searchable in the finder.
My impeller measures a millimetre under the chart figure - same part?
Almost certainly. Worn rubber measures under nominal, and vanes with a permanent set distort the diameter reading. Measure the widest points, count the blades, and identify the drive type — diameter plus width plus drive almost always lands on one row. The finder's size search applies a ±1.5 mm tolerance for exactly this reason.
Is this an impeller cross-reference chart?
Yes — the replaces column carries the manufacturers' own published cross-references in full: Jabsco, Johnson and Sherwood equivalents plus the Volvo Penta, Yanmar, Onan, Cummins, Perkins and Caterpillar OEM numbers they supersede. Search the page for the number you're holding, whichever brand printed it, and the row shows what replaces it.
Why do some impellers list several 'replaces' numbers?
Because the same pump appears under many names — the pump maker's number, the engine maker's OEM number, and the aftermarket equivalents. The replaces column shows the published cross-references from the manufacturers' charts; type any of those numbers into the finder and it resolves to the charted part.
