Hi, I have had a 2000 Gibson 47 Executive Houseboat with twin fuel injected gas 454 Crusader engines and V-Drives, for about 1 and 1/2 years. The boat has a high RPM issue with 1 engine reaching a maximum of 2700 RPMs and the other a maximum of 3000 RPMs, instead of the expected 4000 to 4200 RPMs. Multiple boat mechanics have looked at the issue and not found any problems with the engines or fuel system. I also had the props reconditioned and the bottom serviced and repainted when I purchased the boat. Please help me with the following 2 questions:
1) Can anyone let me know the type of propeller, diameter and pitch that this boat should have to reach the expected RPMs on top end?
2) Has anyone experienced this problem (not reaching high end RPMs) and the problem turned out to be something other than the props?
Any help with this will be greatly appreciated. Thanks in advance.
