"When was the last time the thermostat was changed? If > 2yrs, change it. NOT SURE

All the fuel filters replaced? Yes all fuel filters replaced changed fuel pump last year also

When was the last time the Idle Air Control (IAC) valve was cleaned?" Again not sure I have never done it, how hard is it to clean these ? This is a 2004 115hp mercury 4 stroke efi , Also how hard is it to replace thermostat?
