The Genuine Tohatsu 309-01005-2 Cylinder Head Gasket is an OEM engine gasket used between the cylinder block and cylinder head on selected small Tohatsu 2-stroke outboards. This gasket provides the critical seal around the combustion chamber and cooling-water passages, helping maintain correct cylinder compression while preventing combustion gases and cooling water from leaking between the cylinder head and block.

Maintenance Advice
- A cylinder-head gasket should generally not be reused once the cylinder head has been removed.
- Before installing the new gasket, clean and inspect the cylinder-head and cylinder-block mating surfaces. Check for corrosion, distortion and damage, particularly around the combustion chamber and cooling passages.
- Cylinder-head fasteners should be tightened in the correct sequence and to the torque specification given in the appropriate Tohatsu service manual.
