Questions & Answers
Is this a genuine original part?
This is a premium replacement part designed to meet or exceed original equipment (OE) standards for the 2-cylinder EFI platform.
How do I know if it is compatible?
This gasket is specific to the EFI (Electronic Fuel Injection) models introduced around 2017. If your engine has a carburetor, this will likely not fit. Check your serial number or existing gasket against the 3RS prefix.
Will this fit the 9.9HP model?
Yes, it is fully compatible with the Tohatsu MFS9.9E and Mercury 10HP EFI models which share the same block as the 15/20HP versions.
Note: Professional installation and proper torque sequencing are recommended when replacing cylinder head gaskets. Always verify fitment via your engine's serial number at 4boats.co.uk.
