[C320-list] Cutlass/Shaft/Engine Alienment

[Kirk McCullough]

You may have the Perkins engine as I do, on a 1994 boat, which as far as I 
know did not have cutlass issues in general. Mine had over a 1000 hours on 
it before I replaced it while upgrading to a SS shaft and a feathering prop 
last year.

The Perkins do have a tendancy to shudder at low RPM however, so this will 
put some additional wear on the cutlass I suppose, but then again, mine 
lasted a long time.
