Friend of mine has a 25 outlaw with a 496HO stock setup. On a normal day you can push the throttles forward and run all day long. All of a sudden he said he started to hit the rev limiter which never had happened before. Now the boat can only get to the 3/4 throttle before hitting the limiter. RPM's and speeds are all normal.
Was told it wasn't linkage or coupler.
Prop is in good shape. No signs of dings, nicks?
Any ideas? Could props blades have warped, etc to a point where it can increase RPM's?

About 7 years ago, I got a little wild one day on my family's SeaRay 290 with a single 496 HO and guardian mode kicked in. Boy were they pissed when I had to explain that one

A clarification is needed for me. I don't see where he says the rpms or speeds are off.

Just to confirm: Speed has not changed. Still maxing out around 73MPH which is what it would do at Full Open Throttle. Only difference is...he reaches 73mph and the motor starts bouncing off the rev limiter (Baja's begin to beep and the motor cuts in and out as it taps the limiter) RPM's I believe on a 496 HO are 5050 (or 4950 can't remember) but whatever it is it's tapping the limiter. Throttle is at 3/4 now. If he takes it beyond the 3/4 it just keeps tapping the limiter non stop.
