2005 6 Hp 4 Stroke Mercury Stalls

I recently purchased a boat with a 2005 6hp 4 Stroke Merc troller. It starts up great, no problems but after it warms up after about 5-10 minutes, and I apply the throttle it bogs down and dies. During warm up it will run full throttle for a little bit. After warm up and dumped into gear it will bog down and die as well.. Things I have done/checked: New fuel filter, took apart and cleaned the carb, checked the fuel pump (it looks to pump fine, not sure if it is enough pressure), checked the plug (will replace as it has some black soot). I am not sure if there are any carb adjustment screws that I missed but the screws I took out of the carb seems to be tight? Any thoughts or direction would be greatly appreciated.

Is there an idle adjustment screw on the 6hp? If so where. Thanks

There may be 2 screws w/springs...one is idle and the other is high speed.

I finally got it fixed. After watching a couple of Youtube repair videos (Nissan & Tohatsu are the same) I cleaned the carb again, changed the plug and adjusted the idle up a touch. It now runs like a top. It is fairly simple.
