I have a 2003 38 Open with the same engines (6CTA 8.3) and have been winterizing them for 15 years, with the boat staying in the water for the winter.. I run 6 gallons of Non-Tox antifreeze through each engine using the raw water strainers as well.. Works for me. May be over kill but better safe than sorry. M2C
