250 EFI fuel economy? No such thing. Mine gulps it, but runs like a striped aped. Cool video buddy Trim that thing up a bit and you'll see another 5 mph from it.

I was trimmed out. I don't have enough prop. Running a 26p Tempest Plus worked by Josh with added cup. Need a 27p Fury. Need to get that battery out of the front compartment, too.
LET’S GO BRANDON!!!

I've never calculated it, but WFO, probably less than 2 mpg. Cruising at 4K, maybe 4mpg.
These motors run the cleanest at about 4500-5000 RPM's. They are thirsty for gas and oil. (If it's an XB like mine, require 91+ octane).
Solid motors. But, get a leak-down test done to check the motors health. Also, send the induction system off to be cleaned and injectors calibrated. European Marine or Brucato have the equipment to properly do this. ^ this...get your injectors cleaned and calibrated, with an EFI always remember your fuel injector is also your oil injector and the lubrication for that cylinder..if you do this about every 3-4 years that EFI will last a long time! But it is going to love gas! Wide open the fuel curve is about the same as a Optimax however everything else RPM range your efi is going to get almost half the mileage (thats comparing 250 xb vs 250 opti)
