This is most likely cruising between 22 to 24 knots. Does the running angle/attitude look right?

The boat feels and rides heavy. It is getting 30 knots at WOT with 300hp cummins. 24 knots at 2400 rpm. Depending on how it is loaded. 4 blade dqx wheels.

I anm just shy of 30 knots at WOT with the 270's. I think you need to check the size on those wheels. What transmission reduction are you running?

You should be over 30 knots at the top end. I am at 24 knots also at 2400 RPM.

Maybe he is propped for 250hp? Are those Cummins CPL970? They should be underpropped if they are. What is your WOT RPM?

They are the older model cummins and right now they are propped to reach 3000 rpm at WOT.
