Important – Check Compatibility
Please confirm your engine model, serial number and original carburettor part number before ordering.
Different carburettor assemblies may be fitted to engines with the same horsepower, particularly across different production years.
If the part looks the same as yours, this does not always mean it is correct for your outboard.
If unsure, contact SSI Marine with your engine details before purchasing.
