Volvo 260A Thermostat 140 or 160 degrees?

[Russ Preves]

Hi All,
Recently I've heard if you're running primarily in fresh water, you can go to a 160 degree thermostat to make the engine run better....(not as rich)....and that this would help at higher altitudes...say 3700 ft (Lake Powell)

Thoughts?

Shouldn't hurt a thing.
