So I was out riding this weekend when the boat started to have a vibration. Even though I didn't hear us hit anything I immediatly thought that something had bent the prop/shaft or was wrapped around it. I stoped the boat and dove down to take a look but I couldnt see anything wrong. I idled back to the ramp, but the boat on the trailer and noticed a very small bend on the tip of one of the blades. I was able to use a pair of pliers to fix it, but after I put the boat back in the water the vibration was still there.
My question is how much of a tolerance does a prop have before it causes a distinct vibration? Also, what else can cause that type of feeling?
