Doggy Cat
I have a 2001 28 Profile Cat. 500 EFI, extension box, that I just bought. Running a 28 four blade with 60 gallons of gas. It does 72 gps at 4400 rpms. Does anyone have an idea what could be wrong. Profile says I should be doing 80 plus at 5300rpms but does not offer any suggestions.

Re: Doggy Cat
I have a friend that had the same boat w/o the extension box. Did 80+ any day of the week. (I love the boat.) I have to say that sounds like a motor problem. I don't think the prop sounds too big, and efen if they really f***ed up installing the box, it shouldn't cause this.
I'll try to remember to ask him what prop he was running.

What gear ratio in the drive? A 28 on 136 gears and the 500 wont really pull it. Is it a labbed 28? If its is and the gears are 150, then I am afraid you prolly have a sick motor. A 25 daytona or Talon with a 500efi will run just around 80 to 83 at 5000 to 5200 rpm with a 150 gear and 28 bravo or a 136 gear and a 26 bravo so you should be right in that area if all is working correctly.
