Volvo Penta Saildrive Prop stuck open

I'm new to the whole folding prop thing.

Recently we replaced ours with a new unit. When bringing the boat home we were running a bit behind and I wanted to clear out the cobwebs so I push to 2800rpm. After about a minute the boat suddenly started vibrating. not terrible but enough to notice and back down.

In neutral all is smooth. In gear the boat vibrates in reverse and forwards (both gears work) with the vibration starting at low RPM and increasing steadily as RPM increases.

Looking under the boat the propeller seems okay, but stuck open.

Any ideas what might have happened?

Lesson: I had a shakedown sail, I should have pushed the engine harder then.

Best guess fishing wire? Props nice simple mechanical devices and otherwise unlikely to go wrong until worn out / bashed with something?

In the end this turned out to be grease that had coagulated hard in the prop teeth. Since this was cleaned up the prop has been working great again.
