And it also had to do with the change from flywheel hp ratings to propshaft. The old 235's were flywheel rated, and became a 185hp when they went to prop shaft rating.

If one looked at the Euro transom design of the V21's from the inside it became evident why Wellcraft dropped the HP max. The bubble of the transom was not IMHO fully secured to the hull. There was a gap of almost an inch on both sides where the bubble came thru the main flat transom up to the first stringer. Why they didn't fill/glass in that gap and attach it to the stringer remains a mystery to me to this day, but when I removed the floor of my V21 to replace the rotted wood underneath and saw the gap it was one of the first things that I strengthened with filler and glass. I think that Bgreene also has strengthened his V21 the same way after learning of it.
