Question on prop

[TomParis]

So I pulled a boat in today that was out close to the lighthouse, it was a 20 ft boat as well. My question is, after pulling that boat for almost an hour at 5 mph my boat seems to be not running right.

My Question is, would putting my motor under that stress cause my prop hub to fail. Feels like the prop might be slipping not a full fail but not running exactly right either.

Let me know what you think

Appreciate it

Tom
