How the wheels are driven, what gearing, positioning all have a part in determining whether you are on the right track.
I count 6 blades on the wheel, not sufficient. 12 is the norm. If a stern wheeler, the steering must be placed before your drive wheels
What manner of motor, and will the linkage be belt, worm gear, piston arm.
I'm guessing the platform will be at least 12' x 6'? It's an interesting challenge you have taken on. Looking forward to seeing this develop
