==========================

I've seen quite a few twins with separate starting batteries, and the
better ones have a parallel solenoid that can be kicked in if one side
is weak. My old Bertram even had a separate parallell solenoid for
the generator in case that battery was low. Are you talking about
twin outboards or inboards?

And on a diesel rig the same plumbing is necessary on the fuel return
system as well to prevent overfilling any one tank and pumping fuel
overboard via a tank vent. In fact some fuel injected gas applications
return fuel to the tank(this is the exception),although most reciculate
fuel at the engine,it is worth verifying before doing any plumbing,,,,
Hey Butch,what do you think of those optimas? I've had good luck with
them myself...

Wayne,

I was talking about twin inboards but my comments apply to either. I don't
intend to brag but I know a bit about power reliability due to my background
in enhancing power reliability in critical DOD C and C facilities.

The ability to switch between and/or parallel battery banks is extremely
useful. But, two banks are required for redundancy. As I'm a belt and
suspenders kind of guy I run twin Optimas for my small outboard and carry a
12 volt jumper package for additional backup.

Twin tanks are required for true redundancy, also. The best arrangement is
to be able to run both or either engine from either tank using ball valves.
An arrangement drawing is very useful when mounted adjacent to the valve
rail. I also recommend redundant fuel filters for each tank with the
ability to switch between them while the engine is running. With that
arrangement it's possible to continue to a destination in the event you get
a load of bad fuel. Quality filters/separators are the way to go.

Don't for get to carry a spare prop. A couple of weeks ago a fishing buddy
spun a hub shortly after launching. Fortunately we were able to idle back
to the ramp, recover the boat and change the prop.

Bertram, being a very high quality boat, IMO, is constructed in a very high
quality manner with the proper systems for safe offshore use.

hey Butch,
My first experience with the optimas sold me..I was given two
yellow-tops that had been taken out of an RV that was being sold. They
were dead, so I put a charge on them, and they sat on the ground next
to my shed for 9 or 10 mos. One day I decided to wire up some 12 v.
flourescenrt lights in the shed, I connected a charger but they didn't
pull any amps,Imagine my surprise when my voltmeter showed 12.7
volts..I used them for a couple of mos., then donated them to a friend
with a motorhome in need of house batteries...Last I knew he was still
using them...They seem well suited to the marine apps. due to their
construction, they are not likely to experience the plate breakage from
the bouncing around that can sometimes happen to standard wet cells.
They work for me, anyway...

========================================

Be careful with the jumper cables. I know a guy who started a nasty
electrical fire on his sailboat by getting something crossed up in the
heat of battle. I'd much rather have a paralleling solenoid, no
sparks, no mistakes.

Mark,

Excellent points on the diesel fuel return lines, thanks.

So far so good on the optimas. I've had them for less than a year but my
expectations are high.

Wayne,

I agree that jumper cables can be dangerous if not used properly. The worst
example I've seen was when attempting to start a 24 volt equipped bulldozer.
In our shop we had a jumping cart with four large 12 volt batteries set up
to provide 24 volts of starting power.

When the mechanic was hooking up the cart batteries the four bulldozer
starting batteries exploded. Made a hell of a mess. Luck was with the
mechanic and he was wearing safety goggles per the shop SOP. Got him under
the shower and he was uninjured.

My jumper battery pack is designed to be hooked up while at zero potential.
When ready to start the outboard the battery pack must be switched on. As
my batteries are in the center console I can turn the pack switch on from
the helm.

Like anything else in boating it's useful to exercise care when jump
starting.

Of course my dual battery setup includes the 1, 2, Off, Both switch. But,
I've seen two dead batteries on boats with the same switch. Murphy don't
you know?

====================

Always. I think the problems and potential for mistakes tend to be
magnified on boats because of the conditions - frequently cramped,
rolling, spray flying, etc. I find that anything I can do to simplify
operation and avoid mistakes pays off in the long run.

WGASA!

He makes the newsgroup more colorful. As do all of the Left and Right

Hey, I guess that makes us all a bunch of "Wingers"
