Questions about 268/270/275

[Gmanoffshore]

I have read several posts about twin 4 stroke/2 Stroke's on 268's with the extended running surface and the renamed 270 with concerns about weight.
My question is about the new 275 DC, my understanding is that this is the same 8.5 hull as the 268/270/273. If it is why have I seen several of them powered with 225 4 Strokes and no comments about scuppers or weight? Did Grady raise the scuppers? Did they shift weight/fuel tanks forward?
I have no intention of dumping my HPDI's just wondering what the difference is.

I do not know if there was a design change but I can report the following observation. I have the 275 with the F350 and with full tanks of fuel and water the water line at the scuppers is about a 1/2" below the base of the fitting.
