Suggest you go to boatdiesel.com and look them (D9s?) up in archives. It is essential that owners do recommended maintenance by the book on these high HP/liter engines.
For sure correct propping to allow rated plus 50-100 RPM should already be in place. This is a heavy planing high RPM vessel and I'd guess has been run at high loads. That is OK, but props must be set up right.
An expensive and necessary servicing is removing, cleaning and testing the after coolers. If not done about every 3-5 years again be careful. Nice boat from what little I know of them. Good luck and keep us posted.
