Good To Know
Q: Will this carburetor work on a 2-stroke Mercury outboard? A: No, it is specifically calibrated for 4-stroke engines, so it is not compatible with 2-stroke models.
Q: Does this carburetor come with adjustment instructions? A: Most aftermarket carburetors include a basic setup guide, but professional installation is recommended for optimal performance.
