I might have missed some of the discussion, but where is this vibration? Is 
 it when the you're under sail or when the motor is running. We have a 
slight  flutter in the wheel under sail, but zero vibration when motoring.
 
If it's when motoring, it would have to be either the prop shaft or the  
motor mounts. There would be nothing else that would cause a vibration.

Just another thought you  probably replaced your zincs when you did the 
bottom. Maybe its out of balance  or not tight. alden

Okay, all that  being said, when they realigned the engine one of the steps 
they used was to  put a dial indicator on the very little exposed portion 
of the prop shaft  which is behind the engine and before the packing gland. 
They said there is no  indication the prop shaft is bent. I for one have a 
call into Catalina so that  I might purchase a new shaft prior to pulling the 
boat again. I thought I  would just replace the while shaft while it was out 
and have the prop checked  for balance. I'm also concerned that the shaft 
is too short adding to the  problem. Now the thing that did not occur to me 
was bad motor mounts. One or  two bad mounts would allow for proper engine 
alignment, but might tend to  amplify the natural engine harmonics of a three 
cylinder engine. Any idea of  what a bad motor mount looks like other than 
the rubber falling on my feet. I  guess having two people on board while 
running the engine at speed and taking  a look at the movement in the mount 
would probably be th
e best way.

I'm behind on my emails and didn't see Alden Andre's reply before I  added 
to Steve Smolinske's reply. I see Alden also suspects a bent prop shaft  as 
I do. GMTA By the way, when I put a flex coupler and flex flywheel dampner,  
I had a stainless shaft made. My bronze shaft was OK but I wanted the 
stronger  stainless shaft so it wouldn't be as easy to bend if or when I manage 
to  damage my prop. Tom Troncalli > [Original Message] > From: alden Andre  >

I think you have a bent prop shaft. It is what  probably loosend your strut 
in the first place. Or it could be a out of  balance prop. I have the 
standard fixed two blade prop and have no vibration  at low or high power

Now it makes sense. I thought you run the wire from the alt directly to the 
 starter, and I was thinking how you were using the new switch, but if you 
have  it directly hooked up to a battery bank it should be working great. > 
I  have almost the same setup but the alt wire runs directly to the house 
bank. I  was going to use the same ACR, but since I have different battery 
technologies  I went for the echo charge(just 15 amps, but enough for a 
starting battery)..  > I agree with you that the charging system has never worked

directly to the starter then on to  the battery switch. The wires that use 
to lead the current up to the ampmeter  and then back to the starter (red

completly isolates the house  and start banks with the exception of emergency 
combine, just one choice on or  off for normal operation, no more 1, 2 or 1&2 
to confuse the admiral. It  also turns out that the problem most likely was 
an incorrectly installed ACR,  there are two important small wires that 
allow the ACR to sense both banks.  Even though the ACR wiring was probably the 
culprit it is a nice > feeling  after tearing things apart to realize that 
all that current from the  alternator is no longer going through two 
undersized wires and a suspect wire  harness but instead is being carried by a 
battery cable to the batteries. >  > Steve > Peregrine #312 > Seattle > >

are correct.  The
30 amp fuse in your charging circuit is too small to carry the  load if the 
batteries are discharged or you are running other high load  applications.

high amperage load to your engine control panel is not only a  lot of 
electrical loss but it can be dangerous if your harness connections are  corroded.

your battery bank is shorted, you will only be creating heat on the  harness

amp meter giving you a false sense of security. A volt meter gives a  better 
idea of your charging and battery conditions. > > A more  practical solution 
to the amp met
er is to replace the original amp meter  with a marine grade volt meter. To 
do this, you run the output of the  alternator directly to your battery 
banks and use the original wires to the  amp meter to feed a new volt meter.

solenoid since it is very close to the  alternator making a very easy 
conversion. > > The volt meter conversion  is a very good and highly recommended

Basically this allows you have something like #8 or #10 wire  jumper
between the starter solenoid and the alternator, then heavy  battery
cable for low loss to the battery.  You MUST have large #2 or  #4 wire to
the battery to carry the literally hundreds of amps that the  full start
and preheater require.  There is no need to run that heavy  a wire to the
alternator, where it would add mechanical load that the  alternator
designer did not expect.

 it  isolates the two banks except when you need to combine for  
emergencies.   Rather than choices for which bank to use the old 1,  2 or 1&2 it only 
has on and combine.  In the on position both banks  are providing power one 
to house one to start but are never combined unless  you choose the combine 
option.  To charge all you do is select on and  start the engine.
