If Can anybody send me a picture of a QUICKSILVER BLACK DIAMOND PROP / 12 1/2" x 8" ????
I was using a 12 1/4" x 9" prop and that one hand rounded edges all around each blade. (No noise)!
Now I put on the same prop except it's a 12 1/2" x 8".....
Now I have a "singing propeller" between 1000rpm and 2000rpm.
This prop has a knife edge on the TRAILING EDGE of each blade!???(it's pretty sharp)
i haven't heard back from an email to MERCURY yet, but I'm wondering if the sharp edge is supposed to be on the 8" pitch when the 9" pitch prop doesn't have it!?
(I tried to attach two photos but it won't let me!
)
