I have the stock prop and a 4mm plastic one, I think by Octura, that says 40 5 K on the hub. With the Titan 550 12t, one of these props, and 6 or 7 cells, should I expect the boat to exceed the stock performance? I'm not looking for amazing speeds, just a bit better than what it was.

I finished the motor mount and got it bolted in, just waiting for the shaft coupler to come in so I can make the final changes to the driveshaft and get it all hooked up. I also took off the turn fins and filled in the holes because I read cats don't need them.
