No I do not see a problem if you operate below the point that it starts overheating.

FWIW I discovered this problem after helping a neighbor solve his very similar problem as yours with that engine. The overtemp alarm would go off at 2,600. We cleaned the heat exchanger. It went up to 2,800. We changed the coolant. It went up to 2,900 rpm. But with a squeaky clean raw and coolant system it still would overheat at wot.

After doing all of that I finally saw the Yanmar service bulletin and then it all became clear.
