1. Can't remember, but had it scanned and trued a few years ago with no difference in cavitation.
2. Original OEM
3. 2003
4. Faired the dead wood a year after truing with no effect on cavitation
5. Located in NC, Ct and RI
There is a very definite decrease in cavitation with a squeeky clean hull. The cavitation with a normal bottom occurs at more than 3,000 rpm. Since I cruised at 2,800 rpm it was never a problem.

Thanks for your response to the survey
My issue seems also to be somewhat better with a very clean bottom. It was not noticeable for the first 8 months after I purchased the boat and during the initial sea trial. I have the bottom cleaned monthly by a diver. Some time helps sometimes not so much. The boat has not grounded or had any damage since I am the owner and was in excellent condition when I purchased. After hauling and launching with a fresh bottom she runs good, then after several months it returns. Seems so odd that a slightly fouled bottom is the entire cause.
I am trying to determine from the survey if the issue is prop diameter, pitch or the number of blades
Some have suggested that a 5 blade prop would run smoother.
