See you are new here, welcome to OSE! Lots of great people and information on this site!

To play it safe, I would use the X642 but that's just based on my experiences. I had my pop's Geico dialed perfectly running stock esc and motor with the x642 and GPS'd it around 37-38mph. The M445 works great on this boat too but I have no experience on long term use with it in stock form. Stay away from the X645 you would need a esc upgrade for sure. I have no experiences with the S220 on this boat so I can not comment. Others will chime in too but you can find alot of info by just searching the Geico forums. You can get a good idea of what works and what doesn't.

The M series props are detounged X series props. Look at the blade shape and you will notice the difference. The Ms will unload the prop for a few more rpm while providing a little more lift. Either will work well. I use them both on my cats although the Ms are easier to dial-in imho.
