Went up to a friends place to help him with the boat and the engine is
running way underpowered from where it normally is. When we are going
full throttle it is only acting like a 20hp. I checked the plugs,
neither look corroded, just looks like they have some oil on them.
Checked what I assumed was the throttle just making sure the levers
and stuff were moving their full range. The engine doesn't sound like
it is struggling, and it's not getting as loud as it should when we
open it up, it just basically acting like a 20.\
Thanks in advance!

A funny thing with a lot of the older 2 cycle motors is that they can run on
1 cylinder.
I'd suggest one of these:

if there is spark to each cylinder They are easier to see out of direct
sunlight.
If there is spark then it's a fuel problem. Was the boating sitting for an
extended period without draining the fuel?
