I cruise at about 3200 rpm at about 24kts. I have A/C and heat but no generator. I usually have close to full tanks. My boat has the 5.7s also but they are raw water coooled, something I'll change if I ever repower. My props are standard 15x19 3 bladed aluminum, I think I mistyped in the other post. When the boat was surveyed in 2008, full of fuel and four guys onboard, the boat reached WOT of about 4300 rpm, speed was in the high 30s. I haven't pushed her to WOT since. We usually have lots of stuff onboard so I'm sure we have the equivalent weight of a generator in gear aboard.
