I purchased these from a fellow forum member when I had my 340. They were used when I purchased and I’ve never used them. I had them as a spare since it was much less than the insurance deductible for new props. The props are in great condition, no nicks or dings. With the new boat, it is...

As they were getting ready to launch me today I received an email with these pics. What are your thoughts about the cavitation/corrosion on the props (besides not being good)? Should I not launch and replace immediately, launch and replace, refurbish?

Hi all, something of any 290 AJ owners have switched to 4 blade props and if so what pitch and what was the performance impact. Switched to 4 blades this year and down nearly 600 rpm (hovering around 4500rpm). They said same 22 pitch should be fine, I thought down 1 though. Now they want to...
