Is the dealer an idiot or am I?

You should be able to turn the impeller by hand, can you?

When reaching down through the clean out port I cannot turn the impeller by hand.

In a word, yes.
But hard to tell without disassembly/pulling the pump. You will not be able to rotate the impeller inside the wear ring (without having those disassembled completely), the shaft is literally coupled to the engine's camshaft. But you CAN check the clearance: see below.

If the repitching was done without adjusting the OD (outside diameter) than yes, the impelelr blades could be binding. The reason for that is - the trailing edge (towards the "cone") pitch would be lowered in your case (to help engine spin it faster at altitude/less power), so the blades would be pulled "in" effectively increasing their diameter.

Here are the specs, you could check the gap:

I was wrong about being able to spin the impeller by hand. @swatski knows his stuff!

My boat came from the same Salt Lake City dealer.
I can tell you all they do is tweak the impeller blades on their workbench with what looks like a crescent wrench.
It's not done correctly at all.
Send it to impeller pros and have it done correctly.

Yes, but insist on OD specs, which may require some welding and raises the price possibly, but it is absolutely worth ot. When going to lower pitch (trailing edge) they will need to file only, so no extra charge unless it is needed for other reasons.
