This pump impeller Ref. 129 is a flexible replacement impeller with profile 7 for water, cooling water, and seawater pumps on inboard engines, generator sets, and other marine installations. The impeller has 6 flexible blades and is relevant for, among others, pump installations from Jabsco, Johnson Pump, and Vetus, as well as Yanmar engines and Kohler generators.
The impeller is made of black neoprene and has an outer diameter of 50.8 mm, a width of 22.1 mm, and an internal shaft diameter of 12.75 mm. The hub/shaft connection is designed for keyway drive with profile number 7. When replacing, the diameter, width, shaft size, number of blades, and drive profile must match the existing impeller.
The spare part cross-references to, among others, Jabsco 22799-0001, Johnson Pump 09-827, and Yanmar 124223-42091. In addition, there are documented cross-references from Ancor, Vetus, and Kohler, among others. When replacing, both the impeller's dimensions, profile, hub design, and existing part number should be checked, as the engine make alone is not always sufficient to identify the correct impeller.
Documented cross-references include Jabsco 22799-0001, Johnson Pump 09-827, Ancor 50016 and J050016, Vetus IMP00101, Yanmar 124223-42091, 124223-42092, 128296-42070 and 128620-42200, Kohler 250872 and 229955, and CEF 500129.
Via Yanmar OEM no. 124223-42091, the impeller is documented for cooling seawater systems on, among others, Yanmar 3GMF, 3HM35, 3HM, 2GMFL, 3JH2L-NE, and 2QM. The specific raw water pump can vary between engine versions and production years, and the pump or existing impeller part number should therefore always be checked before ordering.
CEF impeller item no. 16.194.13 / CEF 500129 is a related alternative variant with the same nominal dimensions, number of blades, and profile, but is not the same product.
