thermostat for yamaha 4acs 2 strokes motor year 1986 6e0-159691 model

[MAGIUSSA]

Hi, everybody
I'm interested in purchasing some yamaha outborad spare parts for a 2 strokes 4acs motor.
Could you please advise if the thermostat 6e5-12411-02 fits for this motor or which is the correct part number ?
Could you please return also with the part numbers for the relevant gaskets to be changed when the thermostat is replaced ?
What is the right part number for impeller ?
Thanks in advance
bye

Not sure, we don't have any parts manuals on a 4ACS model to see what thermostat it uses.
