Good To Know

Q: What is the OEM cross-reference? A: This timing belt references part 57-835392Q for Mercury and OEM 3H8-10061-0 for Tohatsu. It is an aftermarket replacement, not an original brand product.

Q: What should be checked before installation? A: The engine serial number and existing belt part number should be confirmed before installation. The timing marks must align with the manufacturer specifications.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
