Motor is 98/97, 3cly, mariner 90hp 2 stroke outboard

Issue is that at wide open throttle the motor just doesn't scream like it used too. Thought I could play around with the high end carb adjustment screw but doesn't appear to have one. Just want to try and get higher RPM out of it. Fuel pump was rebuilt 2 years ago and stator replaced as well. Carbs have never been serviced but I opened them up 2 years ago when I did the fuel pump and they looked new inside. Prop has been replaced several times over the years. Diameter is the same but unsure of pitch. Thoughts?  Also are you still on Lake Martin. Thinking about taking it too you if you are to have a look.  Overall the motor runs great. Idles fine. Starts easy even after sitting all winter.
