My engine runs great and has for a long time.  Just recently while running full tilt the engine suddenly lost power and raced wildly (like it slipped out of gear but it didn't). Now it idles fine and runs real slow (at trolling speed); however, when I accelerate beyond trolling the engine whines (still in gear!).  When I back off on the throttle it engages again but only at slow speed.  I've dismantled the lower unit expecting to find bad gears but everything looks okay to me(?).  Why can't I go fast? Thanks.

i had that problem before and it  wound up being a spun prop hub....you could check the the  prop shear pin too if it has one.

Hello sounds like spun hub. the prop can be checked by marking inner spline and inner hub of prop and test run to see if marks move.
