Hi

I was wondering what kind of speed difference in general these props have? like maybe if i was to try the X430 on a 600bb, then tried it with the X432. would the change be in just a mph or two?

According to the prop chart that I have, it only shows a difference of 2 MPH across the RPM range. If I remember correctly, you are trying to use quite a few cells in this boat. It would seem to me that you could possibly swing a lot more prop that what you have listed above. I really don't know as electric boats aren't my thing.
You might want to start asking your questions in the Electric Boat forum where you will get answers from those in the know.

A bit more info would help giving a, more or less, founded answer:

What boat, size, stepped, non stepped, surface drive, subsurface drive, motor type, number of cells, that kind of thing.

On a stock 600/20 we turn a 37,5K or a 36K Graupner hydroprop on seven cells surface piercing drive, stepped mono-1 hull.

well this has to do with a traxxas blast. It's hull is 24in long, non steped, I think it's a surface drive because the prop kinda gets out of the water and makes a rooster tail but im not shure. The motor is a Graupner 600bb sp, and i am about to get a 3300 7cell nimh.

stock my boat did 16-18 mph. And that was with a stock 540 with a X430 on six cells.
