    Prop Cavitation?

    So my dealer leaves a voice mail. Says he hooked the motor to the machine and got no fault codes no problems. He took the boat out, he thinks the prop is cavitating.

    Here's why I took it back a second time for the same thing: WOT runs fine. At slower speeds it feels like it is surging, kicks a little, runs a little slugish. BTW I'm still in the break-in period.

    If it is cavitating what is the fix, a new prop? What do yall think?

    Thanks
