200RV Hub Corrosion

[rgrigson]

I have a Whirlwind 200RV prop on my RV-8, 1368 TT, the prop has failed an inspection. The hub has corroded around the bearing seats - see pictures below. Everything else is in reasonable condition, and could do some more time if they were matched with an airworthy hub. I've noted in the forum that some 200RV users have had blade issues, and there might be some serviceable hubs floating around. If you have a hub, pls message. I'm based in Bendigo Australia, and will be in USA for Osh.
What to do from here? I have a high compression aerosport IO-375. Open for comments and suggestions.
Cheers

That’s unfortunate. Bearing seat corrosion is a hard stop in my opinion, regardless of how good the blades look. If a replacement hub is available, that would be the most economical path. Otherwise, it may be time to compare the cost of sourcing parts versus moving to a current-production prop with long-term factory support. Keep us posted on what Whirl Wind says.
