Another Newbie Request for Prop Suggestions

I'm currently building a GSX315 V2 LSH from ML Boatworks; my first build as an adult (so-called). I'm planning on running a SSS 3656 2030KV motor with a Flycolor 150A ESC and a single 4S 5200mAh LiPO. I was thinking of buying a few Graupner props to use for testing and learning to drive, but the smallest 2317 is 40mm. Is this too big for a starting point? Also, any suggestions on what to use once the testing is finished? Thanks!

The graupner 40mm will be nothing for that motor.

An octura x642 would be a good prop to try.

Also try the 1814 / 17-45 ABC... Good starting points. You're going to end up with that series of prop. I believe most would agree?

Thank you both; I appreciate your advice!
