[C38] vibration under power

[Don Strong]

Jay: We have a solid shaft coupling on Discrete Charm and no vibration. 
I would suspect that your engine and shaft are not aligned.
I was able to align my shaft in a couple of hours alone. With help, it 
would go faster. Instructions are on line.
I will send you instructions for alignment if you want.
Regards, Don
