Im with you... better mpgs equals more range and less tankering, which is a big deal for 400 mile trips.The SJX gas usage seems relatively good given it's power and performance capabilities. My main concern is reliability. It does appear to be better than an optimax, but no where near outboard reliability. I bit the bullet and threw in the order a couple months ago, now I'm hoping to have it spring of 25. Thanks group listing. I'll check it out, already on South Cental Alaska Jetboats. Good bunch of guys with great advice
