Plenty of power for the boat and she rides ok for a 25 due to weight and tab use. The bigger concern woulld be those motors are kinda heavy for that boat. I had to repower and stayed away from them just for that fact. I bet the scuppers will be underwater and with a full tanks of fuel water will also fill the splash well and that is not good.
Also check the transome
Are all thru hulls still plastic?
Original 12 volt wire?
Original Fuel tanks?
All thru hull hoses still original?
Dont get me wrong I like my Grady but these are things that need to be done on a 21 yeaar old boat or gone over real good.
Good luck :wink:
