    LOW RPM'S Mercruiser 454 EFI

    My '99 Sea Ray 400 Sundancer Tops out at 2700 RPM. What should the WOT be and any ideas on what could be the issue. I have replaced both fuel filters. I also ran a gallon of Sea Foam through it and it improved temporarily to about 3000 RPM. Any help is appreciated.
