4 propellers interfering with each other was the question
The propellers don't interfere with each other because they are side by side with probably 10" - 12" separation between each other.
They all will run in clean water aft of the transom just below the bottom of the boat.
If they were one behind to other or overlapping then they would interfere.

What about tip vortices? Don't they have an effect?

Probably but hasnt the vessel moved past this point and the thrust been used sort of like 2 aircraft being able to fly close to each other when side by side but not behind eachother or when prop engines are mounted close on a wing?
Dont ask me to quote the science cos I dont know it!

Do you think these props will interfere with each other?
