Providing your fuel flow sensor is reading correctly, then those numbers are not that bad at all. Those numbers are actually pretty close to what I burn in my HYDRA-SPORTS, and it's only a 20 footer(but it's a HEAVY 20 footer). Your WOT is a little high, but not horrible. I would have expected to have seen 21-23 GPH at WOT as my 225 that is putting out a bit more than 225 at the prop is burning about 27 GPH at hammer time. I hate to tell you this but you won't see a big improvement in those numbers with a FICHT or ETEC at the cruise speed. Trolling will improve greatly and the WOT will come down, but at cruise I would only expect to see a 15-20% improvement over those numbers. The only upside to going to a modern engine would be you could go to a bigger HP and keep your fuel burn where you are or a touch lower at cruise.
