Cavitation damage to props on 39 open

[bclark65]

I just pulled my 2019 39 Open.  Both props showed cavitation damage, in particular blade root cavitation damage.  I have not added any equipment to the bottom of the boat.  The bottom is cleaned regularly, the bottom is painted every 2-3 years, and rarely do I exceed 25 knots.  Has anyone else notice cavitation damage to their props on the 39 open?  Thanks
