On the water with Vibration in my 2013 G23 - stock prop

[awhitlock3]

On the lake right now , I have a major vibration from 16-25mph
There is no vibration at full throttle, no vibration when in neutral and reave up the motor, and no vibration up to around 10-12mph
Would this be a bent prop blade? Loose prop, I can feel under the water and it seems , ok.
Again I am on the water right now. I haven't hit anything to cause this to be the case, yesterday it was fine....any suggestions?
I plan on getting a new power prop anyway but wanted to make sure this was the problem.

So I think I found the culprit:



The screws holding this to the boat were loose and 1 out of 4 is stripped in there....
Any easy suggestions for a fix?

What happened to the bottom of your boat?

I would say just replace the screws but it probably has to be aligned or something.

The big question is why are they loose? These are locking nuts. Did the prop torque tear through the hull, did it hit something at some time? did the bolt snap and the nut is broken off? you most likely will want to tighten the nuts so the polyurethane seal is not broken or remove entirely and re seal bolts and replace with a new set of bolts, nuts, and washers.

You also very likely still have a bent prop. They will vibrate in and out of different rpm.
