I believe we've touched on what the vent plugs are to do (hit it in the 115 thread), but as people are testing, they have to consider what the boat is going to do in rougher seas when the power is needed most. Determining the rpm level when the exhaust will blow by the holes and out the rear of the prop is an extremely important number to know as rougher waters could have someone dealing with a bunch of slip/surging of the boat if they need a specific rpm to get from point A to point B. Knowing that number will help them navigate, and it may mean they decide to downsize their vent holes to best suit their needs Testing High end is not the intent here as the vents don't do anything at that point as blow-by is what should be going on.
