Important – What Is Included?

This listing is for the individual lower casing cap only.

It is not a complete gearbox, propeller shaft bearing carrier assembly or gearbox seal kit.

Bearings, oil seals, O-rings and other gearbox components are not included unless specifically shown in the product photographs.

Please compare your original component with the product photographs before ordering.

Important – Check Compatibility

Please confirm your Yamaha engine model, serial number and original gearbox part number before ordering.

Different gearbox assemblies may be fitted to engines with the same horsepower, particularly between 2-stroke and 4-stroke models.

If the part looks the same, it is not always the right one.

If unsure, contact SSI Marine with your engine model and serial number before purchasing.
