Stus-List Re: Accurate Fuel Tank Measurements

[cenelson--- via CnC-List]

Unless your tank is a rectangular cube, any measurements based on the height of 
fuel in it will be approximate at best. And even then, if it is not ‘level’ on 
any axis, it won’t be accurate.
For instance, my tank’s bottom is shaped to follow the hull shape for a secure 
fit. Of course, when down to 1/4 ‘full’ by a level sensor, it has much less 
than 1/4 tank by volume.(The same is true for automobile fuel tanks and this is 
why most tank gauges fall much faster from 1/2 full to empty than from full to 
1/2 empty.)
There are gauge calibrators available the correct for this. AFAIK, they are 
calibrated by adding fuel in known increments to an empty tank so that the fuel 
gauge reflects the correct amount of fuel, not the height of the fuel. (The 
calibrator is inserted in the fuel sensor wiring to change the level sensor 
resistance to match the fuel volume instead of the fuel level).
This is likely more accuracy than typically necessary for recreational 
boating—adding fuel when a level gauge reaches ~ 1/4 tank will prevent the tank 
from ever going empty no matter what the gauge reads.
II am not a pilot but suspect that given the consequences of running out of 
fuel at 10,000 feet, a different technology is used for airplane fuel tanks—if 
not, I am sure such tanks are calibrated more accurately than most boat fuel 
tanks!

Stus-List Re: Accurate Fuel Tank Measurements

[Jeffrey A. Laman via CnC-List]

My fuel gage never worked. Last year the 42-yr-old aluminum tank sprung a leak. 
Replaced with plastic tank that is translucent. No need for a gage any more. 
Just look at the tank. 100% accurate.

If your aluminum tank is 40-yrs-old, maybe preemptively replace it? It will 
leak eventually and it's a mess.

Also curious about rationale for keeping tank full. You are in a warmish 
location so condensation would seem to be minimal. Are you concerned about 
never having a fresh tank of fuel, constantly mixing a little fresh with the 
old?

While I have a fuel gauge, it isn’t very accurate as it under-estimates how 
much fuel is in tank (by several gallons).
I’m thinking of trying to use a wood or plastic dowel, but that would require a 
“straight shot” to the tank bottom (I.e., no bends or obstructions).

Stus-List Re: [EXTERNAL] Re: Engine strangeness

[Chris Riedinger via CnC-List]

Any place you haven't checked is ripe for problems.

Any assumptions you make now will seem more obvious in the future.

The simple fact that one thing keeps happening: your engine is cutting out

So you trace back from there, what does the engine need to run? Well it
turns out that most sailboat diesels only need an adequate and precise fuel
delivery.

Some have turbos, some have electronic injection systems.

Most just have a diesel tank that is approaching 30-50+ years old,  along
with mixed components from similar vintages.

Stus-List Re: Engine strangeness

[Doug Mountjoy via CnC-List]

David, on a couple of different engines. I've had the electric fuel pump
fail intermittently. While bringing my Sabre home the oil pressure would
drop off randomly and the engine would bog down also randomly. When both
happened at the same time I began to panic that the engine was thinking of
going south. The boat had been sitting for 4 years. I pulled into the
closest marina did an oil change, no filter change. That helped the oil
problem. As for the fuel issue. When the electric pump got warm it would
quit pumping fuel. Let it cool and all was good for awhile. To get home I
ended up putting a fuel can in the cockpit running a hose to the Racor and
a return back to the Jerry can. It was a very accurate way to see fuel
burn. New electric fuel pump all is well. Had the same symptoms on my hot
rod truck with an electric pump.
I had been told by my broker when I bought her that the oil had been
changed. I don't think it was. Changed the oil and filter again once back
in my slip, and all is right with the world.
Good luck.

On my boat I will drain a tank completely. Then upon refilling I watch the
Guage with each 5 gallons I put in. This give me a much better idea the
amount of fuel left.

Stus-List Re: Engine strangeness

[cenelson--- via CnC-List]

Apparently you have an electric fuel pump. Some of these, at least the small 
one I use, have in-line filters
that are built into the pump and not removable—they are integral to the pump. 
The only way to replace the filter is to replace the pump or have 2 
pump/filters in parallel so they can be switched—my solution.
In my case, my diesel guy completely bypassed the Beta 28 mechanical lift pump 
since it’s lift was thought to be marginal—although this was never ‘proven’ to 
be the cause of my stalling problem. The problem has not returned in any case.
Worth checking at least.

Stus-List Accurate Fuel Tank Measurements

[Peter W. via CnC-List]

I like to keep my fuel tank as full as possible as the best way to keep out 
water.

Can anyone share their procedure to determine (with reasonable accuracy) how 
much fuel their tank holds, at any given time?
While I have a fuel gauge, it isn’t very accurate as it under-estimates how 
much fuel is in tank (by several gallons).
I’m thinking of trying to use a wood or plastic dowel, but that would require a 
“straight shot” to the tank bottom (I.e., no bends or obstructions).
Any thoughts?

Dave,

Start with the fuel tank.  Look for crud in the tank and in the screen for the 
fuel pick up.  Check every hose clamp in the system. Be sure the overflow 
outlet is not plugged.  Be sure top of Racor is seated properly and vacuum 
gauge is tight.  Change the filters just for peace of mind.

Two stories - Racing on a friend's boat.  One the way to the start, engine 
stalled.  EVERY hose clamp on the fuel system was loose.  Tightened, bled and 
made the start.
My genset would start and die. Followed my advice..  Found loose hose barb, bad 
hose, bad clamp, then finally found the problem - the bleed screw was the loose.

Good luck!

Good Morning,

The Jabsco diaphragm bilge pump has lost suction and needs to be replaced on my 
1979 C The original model has been discontinued (37202-). The closest 
match is the 37202-2012. The original pumps at 4.5gpm. This one is only 3gpm. 
Is this the best option or is there another make available?

Good Morning,

The Jabsco diaphragm bilge pump has lost suction and needs to be replaced on my 
1979 C The original model has been discontinued (37202-). The closest 
match is the 37202-2012. The original pumps at 4.5gpm. This one is only 3gpm. 
Is this the best option or is there another make available?

Thanks

I found a better fitting pump.  Many available.  Low clearance in the 34 C 
bilge.  Many available.

Stus-List Re: [EXTERNAL] Dead Battery Charger

[Della Barba, Joe via CnC-List]

I have a ProNautic  (aka Sterling) 15 amp charger that has worked well for 
years now. It replaced a problematic TruCharge unit.
I only have it hooked to the house bank, if I want to charge the start battery 
I switch the combiner on. Note that you want the temp sensor, gel and agm 
batteries will not charge correctly without temperature compensation.

Stus-List Dead Battery Charger

[Josh via CnC-List]

This is a long one.  Buckle up.

On my 37+, it came with 2 4Ds in the stbd settee forward of the sink.  They 
were dead at purchase.    To install and replace I had to remove the entire 
settee...which included removing the table.  That area had been glassed in such 
that it made a water tight catchment so in the event of spilled acid it would 
be contained during all points of heel save for a full knockdown or roll.

Upon purchase I replaced the 4Ds with 3 group 27 - on the House #1 switch and 2 
group 29s on house #2.  They were the only available marine deep cycle 
batteries I could source on short notice in Brooklyn NY.  I flattened copper 
pipe to create a bus bar witch bolted the 3 house #1 batteries in parallel.  
The boat also came with a Xantrex TrueCharge 40 which had evidently failed and 
lead to the demise of the 4Ds over winter.  I replaced the original Xantrex 
with a larger Xantrex TrueCharge 60.  It had 2 charging channels which was 
convienient for charging the 2 house banks.  The NEW 60 amp charger didn't make 
it past the 350 mile delivery trip before failing as well.  I promptly returned 
under warranty and replaced with a ProMariner ProNautic P1260.  I've been very 
satisfied with it.  My only complaint is that the remote display does not allow 
control, only observation.  Generally this fine but in order to initiate an 
equalize charge you need to access the charger directly.

I successfully mounted to charger to the back of the nav station drawers.  The 
location works great accept for the formerly mentioned need to access for 
equalization.  It has 3 channels of which I only use 2 but leaves room for an 
additional start battery.  In 12 years of service this charger has never left 
me down in any way.

In 2016 the NEW deep cycle marine batteries I'd originally sourced from Auto 
Zone began to fail.  I finally had time and money to properly source batteries. 
 I modified the previously glassed battery box under the settee to fit four 6v 
golf cart batteries.  I got Trojan T105-RE.  The RE is specifically designed 
for solar/wind generation storage systems.  Each one has about 225Ahrs so a 
bank of 4 arranged (series/parallel) to produce 12v results in 450 Ahrs of 
storage.  I bought the watering system to go with it so as to monitor water 
level and simplify watering when needed.  I wanted batteries with flush bolt 
down terminals but ended up with an upright bolt terminals.  This ended up 
requiring a 1x2 wood shim around the perimeter of the settee bench to add the 
required height to accommodate the terminals and bus bars.

I've later added 200w of flexible solar and two 8amp  Genesun MPPT controllers. 
 I typically get ~70 Ahrs per day of charge.

More information available upon request.

Recall that the max charging rate of a standard lead acid battery is 25% of C.  
C being the AHr capacity of the battery or bank in question.  So my 450AHr bank 
should be limited to 110 AHrs max charge capacity.  60amps is well within that 
limit.
In your case, if you stuck with the 2 group 27s then you'd be at about 200AHrs 
so a 50amp charger would be your max.

Its easy to think that you have no need to charge at 50amps but consider the 
following.  Discharging your battery(bank) below 50% should be avoided to 
ensure maximum life span - So 100 AHrs.  The max charge rate only applies until 
the 80% when the absorption phase begins and the rate tapers off 
logarithmically from 80% to100%.  With a 20 amp charger you'll be at max rate 
for 3 hours (60AHrs) and then a tapering rate for roughly the next 3 to 4 
hours.  If your cruising needs are met by the 100AHr limit and 7 hour charge 
time then stay with what you have.  If not then you'll want to step it up.  On 
our boat we can charge rapidly enough (with the upgraded alternator - 90 Amps - 
and the 30 to 60 minutes of motoring on and off the hook morning and night) to 
be limited in our range not by the electrical supply but rather the fresh water 
supply.  I can usually stretch the tanks 4 to 5 days with showers for 2 adults 
each day.

As others have said, you need to consider what type of sailing/cruising you 
plan to do.  If the setup you have has been filling the need adequately then I 
would be hesitant to deviate too much.  In that case, my simplest and cheapest 
advice is to replace the charger with a ProMariner pNautic 1220.  Sterling 
makes an exact match.  Feel free to price check between the two.
