Yes, a good engine survey should cover this. I just had the heat exchangers service with new exhaust elbows installed. I ran the boat with the mechanic in the engine room. We ran it up to high idle to check the governed top rpm. Then we took it out and after a warm up ran the engines at top speed. This while checking temperatures at critical points of water flow and exhaust. The engines turned their rated rpms at 34 knots. All points were checked for leaks and waterflow. All this should be done on an engine survey.
There is a lot of money in that engine compartment. It is good to know the engines are running in top form.
Edit: Forgot to add that the tachs were checked with an optical tach while doing the check. They were withing 50 rpms. With the synch on they were dead on it. She was smooth and ran like the clappers.
