I ask because it is possible that they are adding air when you run it so near the surface if you left them out, thus creating a loose feel - just a thought.
Yes, the Merc PVS vent system gives you all types of sizes to fiddle with. In my application I have to run all 4 vent holes open or else the boat won't come up on plane easily. I'm going to run the Rev4 again and try and get a cell phone video of the blade area water contact patch at 55mph cruise and then WOT as well. Let me know how deep your drive is and maybe you go-pro your Rev4 test.
