As you can see in the picture the shear pin will go in one side but then hits the edge of the thrust washer on the other side.
The hub is a bit crooked in the prop.
I would like suggestions before I do my idea. Which is use an arbor press
Or
Run the motor without the thrust washer but prop is kind of wobbly

Take a hammer and whack it in. Seriously, the hub has spun a bit at some time. Normal for it to do that under overload, or it may be torn loose and continue to spin. You’ll find out when you run the boat.

Garry, no clue as to why it does this, I looked and saw that the post had one hidden post, I clicked that button and viola your post appeared…
I will contact Travis to see if he has any ideas…

If it were my motor, I would grab the blade closest to the shear pin and push forward hoping to rock the unit a bit so the shear pin will fit. I am sure that the hub is cocked and from the
picture it appears that you will not be able to get the shear pin cover over the end because of the pin sticking out. So you will have to take a hammer and tap the pin so it rides over the brass spacer. Once the pin is in place, the cover fits and the cotter pin is in place, take the motor out for a ride. Hopefully the torque of the motor will correct the hub and make it more centered.

Take a punch or marker and mark the hub and the prop. Go run the motor behind a boat in the water. If the marks have moved the hub is spun. New prop time or hub.

OK got it
Is there a way to tell if the hub is spun while on dry land?

There is, All you need is the special tool test fixture to hold it and apply the torque. It should hold 150-180 foot pounds of torque. I made myself a test fixture back in “The Day”. It broke a hunk out of a prop blade.
