I have a 2005 Johnson 150 (J150PLSOE). Took it out for a spin and everything was running great until it loss power. Engine never dies out and only gives the issue in the linked video of not passing 5 mph or 2300 RPMs. Does not appear to be SLOW system.

When the issue first happened I did check the fuel and noticed that I never changed a inline fuel/water( installed by old owner ) filter that was hidden out of view. when I drew fuel after the filter it was milky yellow in color. but the tank fuel is ethanol free clear gas. I pulled out 45 gallons to check for any water in the tank and I could not find any other fuel with the issues again after I changed the filter.
Items I have changed or checked and still cant get it to run:
-Power Pack , coils, spark-plugs and optic sensor replaced ( CDI Package)
-Had carbs cleaned by a mobile mec and had pressure checked (105 PSI in the pistons)
-Fuel/water filter changed
-Fuel lines going to engine checked and new some lines updated. 50 gallons of fuel pulled out and checked for water. No Water in thank. good pressure on the hand bulb
-Temp sensors checked. Does not appear to be in SLOW or stuck on SLOW. Grounding temp senior gives me a red warning light. All light turn on during self test at start. Resistance checks on temp sensors and wiring appear within range.
-Placed a block under the prop and hand tighten prop lug to see if bushing was still good. The check line I drew did not move.
-I did notice some fuel came out of the vapor assy when I over pumped the hand bulb once in the beginning. The mec told me that was fine and it was made that way to release pressure.'
I just installed a new VRO (Fuel/oil pump) a few minutes ago and tested it in a large bucket of water, Engine still does not sound strong when I rev it up. Still sounds like the video.
Does anyone have any idea what could be wrong? Maybe I missed something. My next step is to set it on fire at this point.
