Ah, OK. Forget my first reply! That is one compact lump...
Couple of thoughts -
-Any water in the hull? "moveable ballast" never helps bows stay down, and with 225 on the back you probably won't even notice the extra weight - 'till it moves aft!
-Are you trimmed right in when you take off?
-How heavy is the boat?
As said above, that's a lot of gee gees for a relatively small boat. Have a play with the power trim. (trim right in for start) also a higher pitch might reduce the "0-60 (or 0-100 if you are metric!
)" a bit, calm the attempts at back flips & give you more top speed.
What's it's max revs if you open up & let it go?
