Hello, my name is***** you for allowing me to assist you today.
Is the boat left in the water? Or on a rack?

It is not required for after every time that you operate the engines. it would be great if you could flush them out. There is a zinc anode inside the exhaust plate that will corrode faster than what the block will. As long as you are maintaining the engines properly, water pumps and all zincs yearly, it is ok to only flush them every few trips.
Please let me know if I did not answer your question.
