seaplanes do run ups while taxiing every time. I've done a run up while backtracking at Maree because the place was busy and congested, however I was the last person to use the aircraft and it was ok the night before and I had been using the aircraft continuously for a week so I thought I knew it's behavior reasonably well enough to spot any obvious deviation from normal.
the 210's all did their run ups about half an hour before loading pax.
