The impeller is black and has CEF part number 500385G and manufacturer code 385. The primary Yamaha reference is 6H4-44352-02, which also appears in the formats 6H4-44352-02-00 and 6H4-44352-02/00.

Compatible engine models

The variant-specific compatibility includes the Yamaha/Mariner 2-stroke models 25J, 25Q, 30D, 40H, and 50D as well as 4-stroke engines of 25 and 40 hp. Documented Yamaha applications also include 25 hp from 1999, 25 MHZ3, 30MH, 30EH, and 30ERZ from 2001, 25 MSH3A and 30MSHA3 from 2001, 30 hp from 1987–1995 and 1997–1998, 40 and 50 hp from 1984–1994, 50 Jet from 1986–1989, P50 from 1991–1993, and PRO 50 from 1987–1994.

Other documented cross-references are Sierra 18-3068, GLM 89900, Mallory 9-45601 and 9-45601-10, Albinus 06-03-069, and Recmar REC6H4-44352-02. The Mercury/MerCruiser numbers 804009, 879127, and 47-8M6013997 appear as spare part cross-references, but do not document compatibility with specific engine models.

Always check the engine/drive model and original part number before purchase. Preferably match the engine's existing spare part number with 6H4-44352-02, as engines with the same horsepower can use different impellers.
