maybe you should leave the full cooler on the dock, to get the extra 200 lbs. off the boat before you do a run.

1 to 2 mile an hour difrences are realy not as conclusive as they seem, all though see conditions may have lloked the same, it only takes a very slight diffrence in water, temp or humidity just to name a few, that could result in the diffrence you are seeing. the only way to realy compare props is to test tehm all in the same outing, although I know this isn't possible when you have to sedn yours in to have the mods done to it.
