Okay so the boat is a 2002 Calabria Pro V with a fuel injected mercruiser 383 in it. Present issue is very poor performance. From a stand still I can't get full throttle on it. It seems to perform better if I roll into the throttle slow and only up to maybe 3/4 throttle. It still hits a wall at about 2800 rpm and usually won't rev past there especially with a few people on board. It feels like there's one spot in the throttle travel where it actually works and if can get it right without too much weight on board it will rev out past that point. But not consistently. And it still will only hit about 4200 rpm wide open. So a little background on what I have done to the boat. The motor was fully rebuilt and has about 13 hours on it now, has been this way the whole time. Prior to the motor build everything was working but the motor had huge blow by and oil leaking from everywhere it shouldn't. New parts at the time of the swap was the knock sensor and oil pressure switch. Parts with only a handful of hours before the swap is ignition coil, plugs wires cap and rotor, thermostat, fuel filter, water pump kit. I can't figure out what is causing my issue given it actually performed better with the old worn out motor than it does now.
