454 MPI limiting to 4100rpm lost 8 mph too!

Two months ago I was hitting the rev limiter easily, I haven't pushed the boat very hard at all, the last two weeks it's been limiting at 4100 mph, and I lost 8 mph. Nothing has been changed in the last two months. Seems a "lil" slugish, actually it's drives just like when I had my 3 blade out of the hole. Rams right up to 5100 when not in gear.
