Oh - I didn't imagine this could be such a can of worms Bruce. Basically the answer is "no" to your questions - I get the feeling it's the prop.
I need to get educated so that I can report the issue to the factory and insist on them fixing it. My hand is still shaking from last 20 hours on the tiller! Callum.

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 -- All the best Bruce "Never stay up on the barren heights of cleverness, but come down into the green valleys of silliness."
