Hi
Your present motors will not get your boat up on the plane and will burnout on those props.
The motors would be looking at are B28-57-18L 1600kv,B28-57-17L 1700kv or B28-57-15L 1900kv.
The batteries are OK but you require TWO 45 Amp ESCs with reverse and a Y connector to link to the receiver.
I have a Sea Hornet 25 and 1/4" with a 3s 2650mah on a 45 Amp ESC running a 2blade 32mm prop.
It's dam quick!!!
I tested a 30mm 3 blade prop the low speed was better but the top speed was slower!!!
Also it used more power and shortened the run time.
The 1600kv motors 630 watts each, so twin motors that's 1260 watts(about 7650 watts equals one HP).
Note the props required one left hand and one right hand to stop prop torque.

Shouldn't that be 750 watts = 1HP, or it used to be.
