Factory OEM parts will always have a BEST rating unless there is substantial data to prove otherwise.

Italian-made EMP/HYDRA impeller uses a brass/bronze keyed hub insert and clean molding, suggesting strong dimensional control and positive torque transfer. It should be a high-quality substitute, but the hub construction and tooling marks differ from the OEM NOK impeller so it isn’t an exact match.

OMAX Taiwan impeller shows different hub-face tooling (depression pattern) and no manufacturer/compound markings on the part itself. Expect it to function for fitment, but Taiwan-sourced rubber impellers commonly vary in flexibility and abrasion resistance versus OEM.

Peach Motors impeller is China-made and marked '1.2A', with an OEM-style keyed bore and six straight vanes. Advertised neoprene can be suitable, but lack of an identifiable OEM-tier rubber supplier mark makes longevity and consistency more uncertain.

GLM impeller is China-made with a brass/bronze keyed insert and generic molding identifiers. It will likely work as a replacement, but the rubber compound and QA traceability are less clear than OEM, which can matter for vane wear and heat resistance.

Recmar China impeller matches the basic 6-vane, D-bore layout but has different mold marks/finish than the Yamaha/NOK part. Suitable as a functional replacement, though rubber compound consistency and long-term vane durability are less assured than OEM.
