2008 350 with original stainless steel props. I bought it in 2015. Props were good at time of purchase. Over last year, I've noticed some minor pitting on both rear props, but now I see that one of the props has lost metal, about the size of a magic marker tip. Props are 28-P. I don't run them hard. Boat had 300 hours when purchased in 2015, now has 540. Most of those hours were slow cruising on the intracoastal. I keep the boat on a lift at my dock. I will be taking the rear props off and taking them to a prop shop for refurbishing. Is this likely due to normal corrosion? I keep the props clean, wash them down after every outting. I have used 50/50 mix (water, muriatic acid) maybe three times to get stains off when boat has sat in brackish water at the marina. I don't think the acid caused the issue because its only on the rear props. I read something about cavitation may have caused this, when trimming the props up a little at cruising speed. Could that contribute to the issue?
Here's the 3 worst blades among the 6 blades on the two rear props. The last photo (3rd) shows the blade where metal is actually gone. The other two blades don't have missing metal yet, but have rough spots near the same area, near the blade's outer edge.
