The displayed engine temperature has been a bit unstable recently, it usually sits @ 56 deg C or 133 deg F.
The temperature has been up to 80 C / 175 F a couple of times. The thermostat is the original from 2015 so I'm planning on replacing it.
The catalog shows two choices: 122 or 160 deg F, ( 50 or 71 deg C )
which one is normal?
I guess if my engine temp is usually about 133 then the original thermostat in there now is probably the lower 122 deg F version.
I never use the boat in freezing temperatures, normal ambient temperature is about 40-80 deg F or 5-25 deg C
what thermostat settings and running temperatures do other folks see on their outboards? especially similar Suzukis such as DF 150 175 200?

Why would you not replace it well the same one? What does Suzuki recommend?
