Oh boy - here we go! The experts will be along in a minute, but
meantime:
If it appears throughout the range of prop speeds, does this suggest a
problem in the drive train somewhere? When you turn the prop shaft by
hand, does it bind at any point, suggesting that the engine is not
aligned with the shaft properly?
Does the engine vibrate when the boat is out of gear?
It it's only at certain speeds, presumably this is like prop sing, and
will have to be experimented with by changing the prop/filing material
off the trailing edges, etc etc.
I look forward to an interesting thread ;-0
