6Ft Electric Cracker Box

I want to build a 6ft shallow V mono out of door skins and square stock. I plan on using a outrunner electric 3phase motor, its output is around 2800w or 3.7hp max amps 90. I would like to buy a small surface prop around 5in in dia. I hope to run the prop at 3000rpm/2100w/65amps/34v at cruise speeds of 16mph whats that in knots?

What props are out there?????
I have had bad luck finding anything suitable.

Ther are some brass and steel hobby props up to 130mm or 5in roughly. They are submerged props that would require cutting rakeing cupping. I dont mind low thrust and long legs to get the boat up to plane and max speed. I do want a high lift surface running boat like a Cracker Box. Its going tobe a one seater with tight room for two when needed. I would have to keep the loads down with two but hope there is enough mid range thrust to low plane the hual at 70% throttle with two people aboard.
What do you guys think is this possible with a 3.7hp electric motor. I plan to keep the hual very light no glass just fill and paint and epoxy clear coat. My guess the boat will be 50pounds bare. And a mere 30pounds extra giver or take a few using a 782g brushless motor and li Ion cells. So 80 pound plus me a 190pound person + another 5 pounds in rudder/prop/stuffing box/drive shaft/controls. So all up weight goal is 275 to 290pounds. The hual will be 6'X3.5''

Any thoughts on this please feel free.

 

I have a Hunter ceiling fan motor that is going tobe coverted into a 3phase brushless motor, this one has enough iron to produce an easy 4000w at 70A 60V system. Im shooting for a 100k/V and will terminate in wye with 4 strands of 19g mag wire. I need a custom bell with 40X15x5 N50 neo's. Im going to use lipoly cells in a aluminum protection box with a vent and blower. The vent tube will be off to the side and pointing down towards the water.
The packs I plan to use can put out 100A for approx 45mins.
