Need help

I got a 1988 Mercury 100hp, When I take off it acts like it isn’t even half throttle (low rpm) but i had it at 3/4.

You need to supply more info than "it acts like"
What boat, did this just start or this is a new to you boat?
What prop ?

I believe it’s the oem prop, once u get on plain it’s fine but also doesn’t seem like it’s at WOT. When I take it out next I’ll take a video.
