Anyone have any ideas what this could be?

Today I was out on my 2016 t23 and all of a sudden felt a shudder.  I stopped cause I figured I had brushed a stick or caught a rope etc.  after inspecting I see nothing out of place or wrong under the boat.  Prop and shaft look to be fine but any time I go over 5 mph I can hear a slight squeal and awful vibration.  The faster I go the worse it gets.  There is one small nick in the prop about 1/4 in MAX, I doubt that would cause all this ruckus?

change the prop.  Doesnt take much of a nick or dent to cause vibrations.

Literally the nick is so small I can't imagine it causing any vibration and the vibration shutters so bad you can't go above 10mph.  I have no clue what it could be

Easiest thing to test out, and if you don't have a spare prop that should be the first thing you buy for a new boat.

Probably more then a nick. One of the cups probably has a bend in it that is hard to see. 9 times out of 10 vibration is a prop issue unless you lost some of the coupler bolts

Another option is that whatever caused the nick also bent something. I agree with oldjeep, the easiest way to test is to get a spare prop. It's also one of the best investments for the future.

You could try it on the trailer, in gear, with and without the prop.

Hope the issue is minimal. It's amazing how a little nick can cause a huge driving issue. 

Keep us udated,

A bent prop.  Or a bent shaft.  But probably a bent prop.

And pick up a weekend saver kit with the new prop.

Upon further inspection I found that 2 blades were slightly warped so I must have spun through a decent size stick.  Dropped the prop off this morning to be repaired and should be back on the water next weekend.

Get yourself a spare.  It will save the rest of your weekend.

Mine has saved more than one for my family.
