The motor has been working fine all summer but I was out on the lake and about to head into the landing and when I put it into gear it idled fine but if I tried to go any faster the motor would rev to really high RPM and boat would go nowhere. I've been reading up and maybe it's a prop hub problem? Any suggestions would be much appreciated!

Sounds like a spun hub in the prop. Most of the time you can have it rebuilt (if the prop fins aren't in too bad of shape) cheaper than buying a new prop. Have you checked the shear pin? I would check that first.
