MC-1 Drive Dog failure?

Spent a bit fiddling with it. I already had it at 6"...

I eventually found a setting (backed off helm cable 6 turns instead of 4) that allowed for full engagement both directions and not using up all of my slot adjust (still using about 70% of it). Here's a video of my current results:

I can't get it to not ratchet at all after reverse and reverse not ratchet hard in gear (hand spinning). Going to have to be good enough, at least for now... it's way better than it was!

Did some checking on the other two lower cases I have.

Pulled the TN drive's impeller for laughs.. yeah, it was completly roached. Didn't take out the housing... but no wonder the guide tube was melted! Due to the case damage and stiff shifter, it's not favored for reuse.

The Gary drive needs a new prop seal... it had ran over some netting which took out said seal. From what I'm seeing this can be replaced without tearing the gear case down. The shifting feels good and unlike my current one, seems to be in the right "finger" positions (on the current drive, forward doesn't make it to straight- I think it's a bit past?). The skeg is missing a few chunks but not completely gone... might be weldable. Has a thick and ugly (brushed, not sprayed) repaint job that I don't care for but isn't a deal breaker. The big question is what condition the gears and bearings are in, considering how bad the upper case was. At some point soon I'll pull the lower case and impeller and feel. If the gears feel good, maybe just needs a new impeller and prop seal and would be a good backup case given the suspected wear issues with my current lower.
