@pranavk09,
Looks good!
And super light.

It will probably be 99% out of the water.
Hence danger of being top heavy with the motor on top.
Can be compensated by heavy lipo as low as possible in the hull.

You can also consider making another one of these, and making it a twin hull catamaran.
Motor can be mounted on the cross braces connecting the hulls.
Single air rudder in the center, or twin water rudders on hulls...

Just one caution:
A high mounted motor/prop on a super light hull, will tend to dig its nose in when you increase power.

But more important, build whatever catches your fancy. Then you can build variants.
Good start. Best wishes.

Angle the motor upwards.
It will counter the effect of motor on the boat.
The boat will appear to be 'nose heavy' on the application of power if the configuration you have shared is used.
