DAUNTLESS: Hull Notch at Transom

There is a notch in the hull of some DAUNTLESS model Boston Whaler boats which is in the stern at the transom. I am curious about it. Why it was designed into the hull? Links to photographs would be appreciated.

The 1999 Dauntless 16 has a notch..

Here's some transom notch pictures of my 2002 Dauntless 160. Per Chuck Bennett at BW, a few 2002's had the notch before changing the molds (mine was built in may 2001 as a 2002 hull)

The purpose of the notch is to be a built in setback bracket to deliver cleaner water to the prop and to allow the engine to be raised even further then normal.

If the notch was a good thing why did they get rid of it?

If it wasn't a good idea why did they put it there in the first place?
What are the symptoms that removing it may have cured?

The notch increases time to plane, ability to plane with a large load in the back of the boat. Etc. Raising the motor so that the cav plate is 1"-2' above the keel helps as does a fin on the motor.

Dick--Thanks for the explanation of the purpose of the notch. It sounds quite reasonable.
Perhaps the notch was eliminated in order to provide more hull form buoyancy in the stern to accommodate heavier engines. If the boat is equipped with low-Emission engines, the engine weight may be significantly greater than that of a classic two-stroke engine, so the hull may have needed some modification.
Compare the weights:
Mercury 90-HP Classic two-stroke = 303 pounds
If you want to sell the boat with a larger horsepower, low-E engine, you may need to make some adjustment in the hull form.
