Hi guys, need a little help here. I am still building the boat, so nothing is mounted yet. I know what Mike used on his original build for power. This is what I was thinking of using.

Motor-4076 1700kv
ESC-220Amp SF
Cells-5s2p 6000-8000mAh
Total RPM unloaded=31450
What would be a good starting point on prop diameter? I have read that anything less than 50mm would be to small. That still makes it a Q sport hydro running 5s right?

Yes "Q" I would start with a x447 and go up from there. We can work on it at the pond.
