The temp gauge in my '41 Merc runs 3/4 gauge all the time with 180 thermostats. Full scale hot is approx 212-215 degrees. If you're not losing water it's not running too hot. As for oil pressure, first thing to do is test it with a mechanical gauge. You may find it's higher than the dash unit says. However, even if it's running as low as it shows it'll still do just fine and run a long time like it is.
