    05 225 HPDI lost RPM's

    So took the boat out yesterday for the first time this year. Started off it wouldn't hardly idle off the trailer. So got it out and went WOT. It launched and went to only about 4000 RPM but stayed there. I knew something wasn't right so headed back towards where the ramp was. As I headed back it slowly kept dropping RPM until finally it wouldn't plane off. And it wouldn't hardly idle to get it back on the trailer. I have recently replaced all the fuel filters except the mystery filters in the injectors and HP fuel pumps. Does this sound like mystery filters or could it be something else? I also recently did VST filter and low pressure fuel pumps. Do I need to get the injectors flowed? It only has 115 hours on it and compression is good. Any help is appreciated.

    It's been a few days since you posted. Have you taken this motor to anyone? Did you find anything out?
