2 Blade Propeller

[onibnasir]

After searching for quite some time, I have been only able to find the 2 blade propeller for my ROV instead of 3 blade or 4 blade that I desired. The smallest size that I have been able to find is 120mm diameter. The question is would it work for my ROV with bilge pumps of 1100 GPH. I intend to go to around 100 feet. The current drawn wont be a very big issue as I can compensate for that.

that is a pretty large prop diameter IMHO. The link below for a 55mm a much better choice 3 blade.
