I know theres comparison charts and so on but would like to see if there is anyone who can verify the difference in fuel economy between the two? i know what my GPH are and at cruising rpm 3800 with twins on a 30' i get 25. doesnt include the oil which can get pricey. These motors i have are strong with 600 hrs. and i really want 4 strokers but dont think i can justify it unless there is a huge cost savings? thoughts? maybe someone made the change and can verify first hand. thx
