In my plane, I fitted the "budget" HobbyKing G32 with a 13 x 6.5 prop and on 4S it has a truckload of power. At full throttle it roars off the ground, I was quite surprised when I flew it for the first time - really, power to spare. I'd be supremely confident that even with larger floats and the expected increase weight and drag that this power-train would be more than ample.
By the way, if you like I'll get one of the E-Flite floats out of the box and weigh it so that you can get a better idea of the likely differences between those and yours. Just let me know.
yarrumevets, thanks for response. Per the HH website, the Eflite floats are 28oz so I have a starting point for the weight--just have to wait until the VQ floats arrive to weigh them. Strangely enough, I could not find their weight posted anywhere on the web, just a lot of other references.
Glad to hear the Power 32 seems up to the task, once I know the float weight I will know the flying weight of the model and have an idea how close to 8 lbs it might get. However, still need a little extra for water takeoff. 4S is of course a given, but still may go with a Scorpion or Hyperion replacement--Eflites are not the only motors out there :-) As I say, waiting on the floats before deciding how to proceed...Pete M
