OK, well you can test your theory statically.  Simply shift into forward gear, remembering to spin the prop to ensure proper clutch dog engagement.  Push the throttle lever all the way forward, you shouldn’t have to “jam it”.  Now go back and look at the throttle linkage on the engine.  Is the mag plate hitting its WOT stop?  Is the carb butterfly opening all the way?  Take pictures is you need clarification..

I usually don’t put much stop in speedometer readings, not very reliable.  But, I do put stock in you complaint about not being able to pull a skiier.  OK, so the engine has the original prop, still might have been the wrong prop from the start.  Don’t think it would affect performance that much though.  The OMC part number along with the prop diameter and pitch is usually stamped into the propeller right behind the plastic hub.  So, you could post the number/size here if you like.

Let us know if your theory about the control/linkage not working correctly has merit, hopefully this is all that is wrong.
