I am posting this for a friend of mine that I boat with frequently. He has a Monterey 322 with twin volvo 5.7's. When running the boat at cruising speed the motor temp is fine but when he brings the boat back down to idle speed, the motor temp rises to 215 degrees then begins to go back to normal. Motor impellers were just replaced. Any ideas?
