Prop noise

It just sounds dry to me. Your video showed you spinning the prop in reverse. Did it make the noise in forward as well? When were the cutless bearings last replaced?
 
Better check your nuts!
I could be wrong but sounds like dry bearings.
 
Sounds like cutlas bearing for sure.
 
Cutlass bearing is made of rubber and needs water for lubrication. Noise is fromj vibration induced by rubber bearing rapidly sticking to and releasing from prop shaft. Actually, if the other prop does not make noise, I would check it for bearing wear. If shaft moves more than .005" or so in cutlass bearing, you might consider replacing it.

The not noisy one is the one to worry about? Interesting. I never would have thought of that.

Just out of curiosity, is noise how a layman would check a bearing? I have nothing that could measure 5/1000 of an inch.
 
Either the fog is rolling in, you spilled the beans on the prop or your prop is calling for launch service!

As everyone else says , a little water should lube the cutlass and shaft just as designed. You should be more concerned if there was a grating component such as when a shaft anode slides to the strut and gets ground down & deposits anode debris in the bearing to score the shaft, or if the shaft and prop can be moved perpindicular to the bearing to indicate excess bearing wear.
 
Mine sounds exactly the same...or worse. I'm certainly not an expert, but have been told it's "normal".
 
Talk about a mixed bag of responses.
So wet it down and see if it still does it seems to be what I got out of all this.

FWIW - It made the noise in both directions.

Also there is no play at all, it does not bind, just makes that noise.
Ones does, one doesn't.
 
Yeah I kind of remember hearing it before but actually I thought both props did it.
So maybe the one not doing it is a issue? LOL!

So now another quesiton, if I hook up the thoro-flush units, start up the engines, is it safe to put it in gear for a second to see how it behaves? Assuming i hose it down first.
 
Never hosed mine before and always poped the boat on land in an out of gear before she splashed.
