[C320-list] Early Christmas Present

[Pat Moriarty]

I suspect nothing, my prop is new this year and to hear AB it is all 
my problem. Shaft too long, engine not up to par, bent shaft yada 
yaday ada, Oh just pull your boat for $300 3 or 4 times to sort out 
there problem. If it did 7.1 kts with a fixed 3 blade and dirty 
bottom but now only 6.7 at 2500 max rpm on a clean bottom  not the 
3000 it use to get and any more is just smoke, it is over pitched. 
The increase in speed and no vibration when sailing at hull speed is 
great. The Hurth transmission on the old Perkins says to let in spin 
in neutral not put it in gear as most models say. Let us know if they 
have found there math error yet. This is a cruiser not a raced boat 
and weighs accordingly.
