I just cant get the right engine temp. Only 155F.
Where should I start looking for errors?

This is a none closed cooling engine running in sea temp around 50F.

That engine water temp is ok. You should only have a 140 degree thermostat in your engine to begin with. If 155 on your gauge, leave it alone.

Or do you mean oil temp? If that is the case, thats way low.
