Default Efficient small props.

I am building a 36" Martin Mars 4 engined flying boat. It will have 4 Hyperion 12 mm diameter inrunners, KV of 4100.
Mfgr. tested with a GWS 3 x 2 prop. It turned 22,560 rpm. It pulled 3.7A @ 7.3 V = 27 watts. WOT is calculated @ 42 mph.

Are there more efficient props made in the 3" size ?
