1980 Mercrusier 470 w/ closed cooling. Installed a new (tested) 160o Sierra thermostat & 2.5 gal of fresh antifreeze. Now temperature gauge that always ran 160o cruising @ 3200 rpm seem low @ 150o. Thoughts?

Welcome aboard.

The 160/150 is on the dash gauge? They ain't the most accurate of gauges.
