Somewhere over about 6200 the ecu starts going rich so its a soft limiter. I had a 99 model that would turn about 6800. Turned a 24 and a 28 to the same rpm
I have an '97 200 EFI and was told the Rev. litter was set around 6200 and that pretty much is where she tops out with either of my two props.
