She's not new, 99 200 Vmax, stuffer plates and custom reeds (Chris Carson Marine). Hydraulic jack plate with 2" spacers for a total setback of 8". Usually seems to run best with PTP about 3-4". Boat is a 2001 Xpress X19. Hull is in decent shape, no really goofy bends or anything on the pad area. Currently running a 15" X 23" 3 blade scorpion with adjustable PVS, open slightly. Runs 57.8 MPH @ 6400 RPM, Water pressure is consistently higher around 20 PSI or more. Working with a local prop shop and we're trying to get a 4 blade 25" he sells Solas so, looking at the LR4. I tried a 23P 4 blade 23P LR4 and loved the response and stability. She ran 6200 RPM and 55 MPH. Just looking for some opinions here. FYI, bow rides low on this particular boat setup, better with the 2" spacers, but feels like it could use a little more bow lift. As much as it would be fun to run as fast as this rig can go, most important thing is getting the right combination for consistency, longevity and efficiency. Assuming I want to get my RPM down to 6000 or so... Thanks in advance folks...
