Yet another way of dealing w/ fuel

Ag Av8ter
 

There was not long ago a SM2000 that was near us in Trellis Bay. I
can not remember her name. Her skipper was really a neat guy and
showed me little "Amel" things on my boat. What he did as a way of
providing clean fuel in an "all of a sudden got dirty fuel situation"
was to have another fuel line added to the after tank inspection
cover. Just a tube welded in place that is "several" inches from the
bottom of the tank. The "new" line is tee'd to the original and has
two block valves. This gives him the option of using the original
Amel fuel supply, or picking the fuel up away from the bottom of the
tank at his option.

Fuel Pre-Filter System & Tank Questions

eric freedman
 

Gary,
There ate 3 or 4 baffles in the tank.

The Racor number for the pre diesel filter is INFDW51125 the filter head is
INFDH 12500
This is a 25 Micron filter 5" in diameter and 11" length. It takes a Jabsco
50 liter per minute vane pump with 1" ports. - This idea came from Ian
Jenkins.

My pre filter works as follows;
There is a "y" valve just below the fill cap in the aft starboard cockpit
locker. Straight down position goes to the tank. I only use that position
for the dipstick.
With the valve turned sideways the fuel drops down to the Jabsco pump
mounted directly on the aft engine room bulkhead. From there it runs into
the Racor filter then up to an elbow welded in the aft inspection port of
the fuel tank. I also had a buzzer added to the system to remind me that the
pump is running.
Fair Winds,
Eric

Eric:

How many baffels are in the fuel tank (600 liter size tank)?

Can you describe in more detail how your fuel pre-filter is plumbed, what
type of pump you
have installed etc. I looked at the picture but it isn't clear to me how
it flows from the fuel
filler port into the tank.

Thanks (Tanks) , Gary

Gary,
There is nothing behind the valve except the white plastic screen.
You will need a VERY thin wrench to disconnect the shut off valve from the
fuel pipe.
We used to call that type of wrench a tappet wrench. I could only get it (as
it is metric) from McMaster Carr. I believe that our filters stay so clean
as the fuel is drawn off the bottom of the tank. Thus, you never get a
biology experiment growing in your yank- unlike US boats that have a pickup
tube and allow stuff to build up in the tank.

With careful use of a soft copper pipe as your pickup tube on the "tank
vacuum" you can get to almost all of the tank from the forward inspection
port as there are holes very low in the baffles that allow the pipe to snake
into the other chambers.

I have attached a pix of the Racor system used to pre filter the fuel.
Mine is identical to this one from Ian & Judy Jenkins amel Pen Azen.

Great idea Eric. I really hadn't thought of doing this my self but it
sounds rather straight
forward. Do you know if there is a stand-pipe of some sort that sticks up
inside the tank
at the bottom of the tank where the fuel outlet goes to the shut off valve?
I have been
careful with all the fuel I have put in my tank but even so I am surprised
at how little
shows up in my Racor filters and wonder if there is time bomb waiting to go
off with
retained material in the bottom of the tank.

We also had a 100gpm Racor filter and a 13 gpm fuel transfer pump added to
our fuel system and filter the fuel before it goes into the tank.

I have polished my tanks for the last 10 years myself.

There is also a screen at the bottom of the tank that is accessible only

This is where you will get a clog and can not be cleaned by polishing the

Hi Judy:

I kept my boat at Manuel Reef Marina from Dec 2004 to June 2004 and it has been there
again since November of 2005. Jim Woods is the manager and a knowledgeable Amel guy.
Not only that he is an extremely nice guy. He will even do some minor provisioning for
you to get you thru the first day or two aboard if you ask. He does care taking on my boat
and watches the lines etc. There can be surge conditions at times in the marina
warranting good fender placement and good line adjusting. Yet there has never been
anything major.

I always enter and leave on a high tide (the tide is typically only about 12 to 18 inches).
There is a well-marked channel going into the marina and you must use the slips on the
south east side of the dock. There is plenty of depth there but inadequate water on the
north west side of the dock. Also stay close to the finger docks when maneuvering. The
finger docks aren't wide enough to accommodate an Amel and any other significantly
sized boat side by side so you usually get a slip all to yourself and can stand the boat off
well from the dock to ease the situation when there is some surge.

The only problem you might have entering/leaving is through the last two sets of red-
green channel markers as that is the shallowest part. It can be 6 ft 6 inches here (or
slightly more shallow) at low tide. I have been stuck there once (full fuel, full water, 6
people and junk) and had to kedge off. On a high tide I have never touched bottom going
in or out. It seems to be deeper (and Jim advises) to stay towards the red markers for the
deepest water.

The price is right here as well. It is about $650 per month without caretaking which is
about half of what it is in Nanny Cay (where I couldn't get a slip even 18 months in
advance).

Regards, Gary

Thanks, Eric. We will probably use your process for the next time, but it
looks now like we might be somewhat rushed for time in May because of
impending business requirements. So will be happy to pay someone to handle
it for us this first time. Nice to know that it can be done simply. Thanks

Thanks very much, Gary. Will call him tomorrow. Also glad to hear that
your boat is there now. I had looked up info on Manuel Reef Marina and it
states that the maximum draft in their slips is 6'6" so wasn't sure if an
Amel would fit in there. Great info. Most helpful.

Did you have the fuel tank cleaned and fuel polished in BVI or elsewhere?
Our boat is also currently lying in BVI and we would like to do the same.

We won't be back down there until May. Will try to stop by Trellis Bay &
share that Sundowner and conversation before we head south.

Hello Gary,

What a good idea! Of course I would start bt reaing the engine down
only to fine the fuel shut off valve half closed!!! I am in
Paramaribo, Suriname at the moment, but will return to Tortola in a
few days, and will certainly check it out. I did have the tank
cleaned and fuel polished right after I bought the boat, so your
suggestion would be an easy fix!

BTW: WORLD CITIZEN is on a mooring at Trellis Bay, Tortola BVI, and
any Amel's are certainly welcome to stop by for a Sundowner and
conversation. We should be there for quite sometime.

We hope to see you in Trellis!!!! We are easy to find as we are the

Hello all,
We have a S/M #266 and it is fairly new to us. Question: #266
has the

we were
told it is 80hp. We also have the Amel autoprop. The prop
itself is
clean and the roller bearings that are visable are clean. The
blades
rotate easily. When in calm water she will run at about 7.5 kts
wide
open, but she will only turn up 2,200 RPM. The Volvo manual
says it
should turn up over 4000 RPM. In rough water and head winds, at
2,200
RPM we are lucky to get 3 to 4 kts. Is this a typical situation
for a
SM? Sure seems overpitched. Does not make much smoke and runs
at
90C. Ideas? Thanks for your help. Tony

If you go trough the archives of this site you will see that the low
RPM problem is almost exclusively caused by carbon built up in the
turbo. The side of the turbo that this accurs is on the side by the
heat exchange and muffler. I remember reading a post that explains
the process of cleaning the turbo. I have had 2 Super Maramus with
this engine and both times it was the turbo.

Good luck

Vito

Hello Vito,

Thanks for the reply. I was hoping that it was in the prop, as I
removed the ducting from the intake side of the turbo (this was
when
I was first looking at her) and was able to rotate the turbine
drive
wheel easily. That is where I would expect the carbon deposits,
not
in the actual compressor side. Do you agree? When I went to the
Volvo manual it said that at the operating RPM I am gettng the
engine is only putting out 33HP. (This from memory so my numbers
might be off a bit. I am in Suriname right now and the boat in the
BVI) I also checcked to see if the wastegate valve was stuck, and
it appears to be working correctly.

I do appreciate you reply and any others you might suggest. This
board is a wealth of info!!!! I can't wait to have my wife read
about how to repaint the stripes on the decks!!!!!

Hello Tony

This is not an uncommon accurence on the Volvo 80hp. What you
need
done is to have the turbo charger removed and have the carbon
inside
the turbo removed. This is not a big deal so dont let your
mechanic
make it one. What happens is that carbon deposits built up
inside
the turbo housing and stop the turbo from rotating. Thus the
reduction in power. Once this is done and all things being clean
you
should be able to run at 2700 to 2800 RPM and have a speed of
about
8.5 knots.

Hope this helps

Hello all,
We have a S/M #266 and it is fairly new to us. Question: #266
has
the
Volvo engine that has a sticker on it saying built by Perkins,
we
were
told it is 80hp. We also have the Amel autoprop. The prop
itself
is
clean and the roller bearings that are visable are clean. The
blades
rotate easily. When in calm water she will run at about 7.5
kts
wide
open, but she will only turn up 2,200 RPM. The Volvo manual
says
it
should turn up over 4000 RPM. In rough water and head winds,
at
2,200
RPM we are lucky to get 3 to 4 kts. Is this a typical
situation
for a
SM? Sure seems overpitched. Does not make much smoke and
runs
at
90C. Ideas? Thanks for your help. Tony
