Hello All, considering upgrading from a B28 to a B33 with Marine Power 454's, stock trannies/props and would like to have an accurate nmpg or smpg, please. Thanks.

Hi Mark, Welcome aboard. You can use the search function as this has been asked/posted many times, but for the most part you can expect to burn around 30-32gph (16gph per engine) to cruise in the 18-19 knot range for a pair of carb'd 454's. It all depends on load and conditions, but that's around .59 nmpg'ish.
