New prop, now it won't spin

New guy here but I have rebuilt a few pumps. Did you change the bearings or just the impeller. I have done bearings and had this problem because they were not perfectly seated. If the bearings are the same then this is not your problem.

The prop is a solas yb-sc-k 15-19. The ski is 96 wb1 stock pump. The solas prop chart says it will fit the ski.

No clue here, especially if with the washers it still doesn't spin. I'd assume it spins freely (the driveshaft) without a prop on it?

Maybe a high spot in the wear ring at exactly the point where the prop sits? Does the prop spin inside the wear ring up until the point it bottoms out?

I just had the same issues with a cut back prop, the hub was bottoming out on the hub of the stator section. As long as your blades aren't hitting the stator (doubtful) I would check to see if this is where it is hitting. I took a marker and marked the outer edge of the pump hub and spun the prop a few times while it was just barely touching it. I took a file and chamfered the corner of the hub a bit and it worked perfectly.

The area in red was where I was hitting, knocked that down quick and it freed right up.
