[C320-list] Globe Drivesaver

[Jeff Church]

Maybe vibration is too strong a word. I had vibrations that shook the whole 
boat when I had a 2-blade prop. With the 3-blade I'm down to the usual 
engine noise that seems to resonate throughout the boat and a vibration that 
is just strong enough at certain speeds to rattle the hasps on the cockpit 
lockers.  In any case, the question remains whether better mounts and a 
flexi coupling would result in the boat running noticeably smoother and 
quieter under power.

In addition, I am going to replace the cutlass bushing this season. It has 
about a 32nd of play. I've been told that you should not be able to detect 
any play in the bushing. Maybe that is part of the solution.

As to being able to listen for problems, this boat will never be so quiet 
that you can't hear changes in pitch of the engine or other mechanical 
noises.
