My boat has currently started building this white powdery substance almost like corrosion and our prop is rusting. The white powdery substance is on trolling motor and and the jack plate. Any ideas on what is happening?

How do we save the prop? And fix the white stuff?

It is corrosion. Aluminum corrodes (the white powdery stuff) and steel corrodes (the orangish/reddish stuff, aka rust). The engine probably does have some sacrificial anodes somewhere that need replacing. These are usually made of zinc and will corrode in place of the motor parts. This looks as though you are using the boat in salt water and not cleaning it, or you are coming into contact with some other substance that is accelerating the corrosion. There could also be some kind of battery/ground issue, although I think that is unlikely--but it is possible. Do some research on how corrosion works and apply the knowledge to your situation. Remove the electrolyte, clean and protect.

It is the trolling motor causing this problem. There is a bad ground somewhere and or the brushes need adjusting. I had the same problem on one of my boats years ago and swapped out the trolling motor; problem solved. The electrolysis travels between the two farthermost metal objects on the boat which is trolling motor to the prop.
Boris Marine is the best at solving this problem. Also have the blocks changed out at the same time to get a fresh start. Prop can be rebuilt and put through a heating process to get a fresh start on that also. It is expensive.

WD-40 if it is just surface, get it off quick. If it has aleady broken the surface And created pitting, you'll not be able to keep it off.
Fix the source of the problem first!

I'm not going so far as to recommend this, but I once read to install a common negative ground wire/cable between the trolling motor batteries and the starting battery. I did do that and had no problem with electrolysis. I no longer have that cable connected now and so far (knock on wood) still don't have a problem. My problem, though less serious, is lime accumulating on the lower unit, from the hard water in the river system/lakes down here. A 50% mix of water and vinegar helps remove it.
