2014 P4 Need Help On Performance

Obviously something is wrong with the motor. What will take some time to analyze. Swapping PCMs should not have much of an effect. Probably changed the timing and fuel trim a bit. Very difficult to diagonose over the internet however, so many variables. Unless you have 500 pounds of jigs in the front of the boat, that motor ought to spin that 24p fury pretty well. Why it isnt is a question.2008 Pantera Classic2014 Mercury Pro XS 200

If by CPM you are speaking of the Engine Control Module (main module that controls nearly all operations of the engine, including timing, fuel, etc) then I would say you have yet another bad module. If it ran fine with the one for a 225, theres no reason for it to do what its doing other than the module is not operating properly. As in it sounds like either the timing is WAY off, or the module is not firing one cylinder.Either way, Id be contacting my dealer/Mercury as it is definitely a problem with the engine not functioning normally.Did they send a NEW module or repair the old one? I would INSIST on a new one for a motor that has that few hours on it, assuming it is still under warranty.2017 Sabre FTD AE DC2017 Yamaha 175 SHOMK Fortrex 80Helix 10 Mega SI in consoleHelix 7 GPS SI GN2 on bow

Harrist your boat will perform well if the engine is working as it should be. My previous boat was a P4 and it ran 71 mph every day of the week on top end. Yours will too when your engine is up to par.Everyone should believe in something. I believe Ill just go fishing!

Just ran my classic yesterday. Into a 15mph head wind. 600 pounds of people (3). 50 pounds of dogs (2). reached 71.3 before I reached the point where I needed to turn into the creek that goes to the ramp. MIGHT be good for 71.5 with that load and wind, but probably not any more (2008 classic, 2014 pro xs 200, 26p 3 blade Fury). It has broken 78 a couple of times and is a consistent 76.5-77.5 with just me in the boat.2008 Pantera Classic2014 Mercury Pro XS 200
