I am hoping someone can help me resolve this issue. I purchased a 2000 Pilot 30 this spring. It has a 5.9 Cummins rated at 230 hp. Flat out I can only turn 2200 rpm as indicated on the tach with a top speed of about 15 knots. reading the engine specs I should be turning 2800 rpm wide open. I have been waiting to pull the boat for the winter to check the prop size. I expected it to be over propped. I knew the prop had been changed once and the original prop was given to me in the sale. The original prop is a 22x27 so I expected to find the installed prop to have a much higher pitch. What I found after calling Michigan propeller with the part number is that the installed prop is the same pitch as the original.
Are there other owners of a pilot 30 with a 230 hp Cummins in this group that can tell me what prop size they are running and what rpms they are turning at WOT at what speed?
If this was the original prop size I am at a loss as to why I can't achieve 2800 rpm. I have changed the primary and secondary fuel filters. The engine seems to run strong with no excessive smoke. This has been the same since I put the boat in the water with a clean hull. I purchased a handheld laser tach but never got a chance to use it to validate the installed tach reading. That will have to wait until spring.
Any help would be appreciated
