guys i have a 24 outlaw with 330 hp 454 im turning 4600 rpm with a 21 pitch mirage plus with me alone and with 5 people i spin the same rpm? kind of weird .. any info would be great thanks. i took off a 23 mirage plus and could only see 4300 or so

i used to have the same motor in my 272 used to see 46-4800 never seemed to change much with more or less load in the boat
