[jkr]

Hello.
I need some help.
Rebuilding this hull with leopard 3674 2200
4s 2p 2200mah 45c nano tech
seaking 120a
Do you know the cog for this hull and what prop?
The hull is 27''

Im not familiar with the esc or motor that you are using but Ive always thought the H&M streamers were cool. Being a 27 inch stepped hull, it should scram with this set-up. You could try a X437/3, X440, or X442 sharpened and balanced to start with. Always remember to closely monitor your temps as you prop up. As for your COG I would start at 8 inches measured from the transom wich is about 30% of the hulls length. From that point you will be just a shift or two with the batteries away from its sweet spot.

Let us know how she turns out.

I'll try this set up.
The esc is the hobbywing seaking 120a and i thing with a prop x442 is ok.
It is the first time i use a 4pol motor an i don't know what i have to expect.

Expect an airborne boat with that amount of power. Mine with UL-1 motor hit high 40s with an x442 and didn't like rough water. It ran flat and fast for a 27" boat. Turns were a handful until I added a large turn fin.

My setup:
CG @ 7: ahead of the rear riding surface transom
Prop: m440
Added 8 ounces of lead at the CG

You mean 40 mph?

Okay, 75-78 km/h.
