Whistle

Anyone ever had this or might know what it could be. On my 86sn I am hearing a whistle sound comming from around the prop or shaft area. It only happens around 1000 and then again around 3000. The whisle started when I put the new 540 prop on. {great prop} My strut bushin has a little movment in it could that be causing this, or is that just how this prop does. Never heard that with the older thicker prop. Also That new 540 prop came with looks like some grinder marks on the backside of 2 of the blades, not shure if it should have this or not. But im thinking this may have been done for balance purpose. Anyone else have these marks on the backside of their new 540 or experience that whistle?        Thanks Randy

Thanks for the reply GrandSlam. I made a phonecall and spoke with a tech. and he said there were a few more calls about this same thing. They dont know what it could be. Im not shure I will file the prop. since no one has figured this one out yet, im gona try a few things and see if that fixes it. Their may not be a fix, That might just be the way it is. I'll keep u posted on the outcome

Well I have tryed a few thing and still no change. I might just have a bad prop. When I a put the OJ prop on the hi pitch sound is gone. I am gona send the prop back and get another one. maby thats the prob. I was told a few more calls were sent in about the same problem. I thought is was just me, but im still trying a few more thing to figure it out. maby its just the prop.. I'll keep U posted.   Any input will help.
