Differences Between 275 and 285 Conquest

[Rocketman777]

Hello. What were the major design changes between the 275 Conquest and 285 Conquest in 2006?

Were there changes to the transom and the method in which the engines were mounted? Or, did that happen earlier in the 275 series?

The hulls look very similar up until 2011. I am looking for a used boat and trying to sort out the details. Thanks.
