Moomba lsv 2015 loud

New to moomba and wake surf. My moomba lsv 2015 is so harmonic sounding at low speeds when surfing the boat sounds loud with a humm and little vibration from that hunm. It's brand new...i have whatever prop it came with from the dealer. Brand new bought. Love the boat hate the him
.
All I know is it has a Ford raptor engine. Out put 275 horse.

Help with humm??? Replace propeller?

Thanks

Maybe the prop. I would swap it out with another one first to see if the hum goes away. Easier thing to trouble shoot first.
