1989 27 Santego, twin 4.3l merc w/A1s. Depending on load (and wind when my bridge enclosure is all zipped up) WOT = 4400 - 4800, stays on plane at 3200 - 3600. Normal rpm ranges?
I typically cruise at 1500 - 1800 rpm (6-8mph, gps) for fuel economy and to take it easy on 20 year old, 700 hour engines. I found at this speed the helm is responsive and she handles the wake from the lake yachts hammering down the river very well.
