PartX Recommends

Choose the OEM Yamaha pinion: bevel gears are highly sensitive to heat-treat quality, tooth finish, and precise geometry, and replacement typically involves significant teardown with high consequences if the gearset wears or fails. The OEM’s refined machined surfaces and Japan manufacture provide the highest confidence in correct fit and long-term durability.
