Questions & Answers

Is this a genuine Tohatsu part?

Yes, this is an authentic Tohatsu factory replacement set. We recommend genuine parts for cooling system repairs to ensure the gasket thickness and material meet OEM heat expansion requirements.

How do I know if it is compatible?

Please check the SKU/MPN list above. If your engine is a Tohatsu-built 25hp or 30hp 2-stroke (twin cylinder), this is the correct gasket set for your thermostat housing.

Why are there two different gaskets?

The 345-01030-1 gasket sits between the thermostat and the engine block/base, while the 346-01032-0 gasket seals the thermostat cover (cap) to the housing.

Note: Always clean the housing surfaces thoroughly before installation. Available for fast shipping at 4boats.co.uk.
