Not sure on actual hull weight but the 2125 dry weight is close. It should have a 95 gallon aluminum RDS tank. I am not sure on the 250hp max. I think it is 225 max. I have a 1993 with a 200 Yamaha. I estimated my loaded weight with everything about 3800 lbs. Make sure you inspect it well and tap the entire floor to check for any soft spots.
14 degrees is correct on deadrise but the weight on an early 90's was less than the new. The larger console and bait tank add a fair amount more weight.
