I have a 1995 powerquest spectra 222 xl, 22 degree hull. Powered by a 454 magnum 365 horse. Was running a quicksilver mirage 23 pitch, 61 mph at 4400 rpm,s. Just bought a revolution4 21 pitch, now running 57.5 mph at 5000 rpm. The boat pulls like a freight train now. The acceleration is amazing. With the trim tabs down I can actually plane out with no bow rise. Should be great for tubing.
