Rough Idle and Bogging on Holeshot

[BassCatKWG]

Hello All,

2010 BassCat Puma FTD DC
2010 Mercury Pro Xs 250 (ser# 1B764965) (app. 700 hours)

Awesome boat, have had it for a few years now, 80mph with a lot of chine walk, lol. Recently though, the engine has been missing a bit while idling in gear and bogging pretty bad when trying to get out the hole. It always eventually gets out but something is obviously not right. I am the second owner, the previous owner was a pro, and I have all the records for any service that was ever done to the boat (meticulous guy). I have a service manual and am somewhat familiar with engines. So with that said here is what I have done so far:

1. Changed plug wires
2. Changed plugs/gapped correctly (multiple times and plugs always look pretty uniform (brownish/tan tint) without any carbon buildup)
3. Changed fuel filter
4. Sprayed power tune in cylinders and let set over night.
5. Flushed motor and changed thermostats.
6. Water pressure is good on gauge, strong tell tale stream.
7. Temp is 130 (doesn't fluctuate much )
8. Fuel pressures (psi): running-107, 5 sec-100, 10 sec-97, 15 sec-93, 20 sec-89, 30 sec-82, 40 sec-80, 50 sec-76, 60 sec-72, gradually drops small amount after that.
9. Air pressure (psi): running-92, 5 sec-88, 10 sec-85, 15 sec-83, 20 sec-81, stayed at 81.
10. Compression: 1-112, 2-110, 3-110, 4-110, 5-110, 6-110
11. Pressure at VST: 27 psi
12. Changed compressor strainer.
13. Rebuilt pulse fuel pump.
14. New primer bulb and all fuel lines. (Primer bulb stays pretty tight)
15. New vented gas caps (from BassCat)
16. Pulled red fuel injectors. Checked O-rings and sprayed with power clean, re-installed.
17. Verified spark on all six wires with timing light.
18. Have one new coil and been moving it around in an attempt to catch an intermittent coil failure, no luck, plugs always look the same and runs the same.
19. New Exide 31 AGM with stud mount type connectors that Don recommends.
20. Resistance of injectors is 2.0-2.1- Specs are 1.9 but that is probably my digital meter off. All are the same.
21. TPS ohms good
22. Checked for fuel in air leaks by removing the air rail connection from both rails and running the fuel pump. No drips.
23. New belt and belt tensioner.

That's about all I can remember, lol. Been doing this over the past couple of months. Once it gets on plane it runs like it always did. I plan on sending the 12 injectors off and having them tested and cleaned. I am leaning towards the reeds. I haven't pulled the intake and plenum off yet, figured I would inspect and replace at the same time. I have a brand new set from Chris Carson and am going to install them when I get the time. With 700 hours on the stock ones I'm sure its time whether that is my problem or not. Looking down the butterfly there does seem to be a bit of DFI oil in the bottom of the plenum. Can't really say if I hear a "puffing or wheezing" as these optimax engines sound odd from the start. Always run Don's cocktail!

Any and all comments or ideas from you guys are greatly appreciated. This is my first time posting a thread on here but have been an avid reader/researcher for years.

Thanks!!!!

Forgot to add:

Smartcraft gauges (the ones with needle and digital readout [+ mode - buttons]), never has thrown any kind of alarm, always run non-ethanol fuel and DFI.
