First I want to apologize if this has already been discussed, feel free to direct me to the correct forum as I could not find one that fit this description.
So for the past 2 years or so I have been experiencing power loss at about half throttle. It is not at any certain RPM, always at the same spot on throttle input. About half throttle it looses almost all power and backfires. When I back off the throttle ever so slightly below that point it runs perfect. I can get up to about 28 mph but that's it. It idles perfect and runs perfect all the way up to that point on the throttle then from there on its completely powerless and backfiring. It has spent 6 months or more at a local shop trying to figure it out and after a lot of money and attempted repairs they threw in the towel and said they could not figure it out. Fuel pressure is good, all the sensors you could think of were replaced, impeller replaced, EMC swapped with a known good one and the problem was still present. When I was given the boat back I was told the only code that keeps coming back is low voltage to one of the fuel injector banks. Before I send it to another shop and spend another huge chunk of money I am really hoping someone here might have some tips on what I can try.
