Please refer to the numbered parts diagram in the product images when choosing your kit.

OEM part numbers are used for identification purposes only.

These components are not interchangeable with the earlier 66M-series gaskets and insulators used on selected F9.9C and F15A engines.

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

If the parts look the same as yours, this does not always mean they are correct for your outboard.

If unsure, contact SSI Marine with your engine details before purchasing.

Buyer Responsibility: Please confirm compatibility before purchasing.
