transom exhaust

[brockhaus77]

Dear fellow Vegatarians,

thanks to your encouragement (I promise not to blame you) my wife and
I are now proud owners of Vega 1060. (The diver removed a huge blob of
barnacles from the propeller, so now we should get better propulsion).
I was wondering whether any of your Vegas has an exhaust fan attached
to the transom vent (the round hood on top of the very end of the
boat). We have one, but it seems not to work, thereby REDUCING the
venting instead of helping it. Any ideas/suggestions? Also, there are
two side vents (pointing forward, with metal hoods) on the cockpit
sides. The port one seems to be connected to a hose going into the
cabin (bilge?) - that hose was actually ripped apart and I taped it
back together for now. The starboard one simply ends in the side
compartment - I can't see any connection to the cabin. Is this the way
it is supposed to be? As you might guess from my questions, we have a
problem with "bad diesel smell" in the cabin, and any suggestion on
how to improve that would be great. One final (beginners) question:
How do you know how much fuel you have left in the tank? I was told
that running out of fuel is real bad for a Diesel engine.
In case anybody is interested, I posted some photos at

The vents on the side of the coaming sound like vents for the fuel tank,
assuming the vents are small, one inch or so. The fuel tank must be vented
so fuel vapors can escape as you are filling the tank with fuel. Of course,
the vapors must vent to the outside air, hence the coaming vents. These
vents are critical, so you should make sure the tank(s) vent to outside
using high quality fuel type hose, good clamps etc. If your vent hoses are
failed you may well be getting fuel vapors into the accomodation - not so
good.

Hi Sebastiaan, congratulations on your Vega! a bit surprised that you "site"
is in German language but situated in the U.S.

I have had a look on your photo\'s, the inside doesn\'t look half bad!
By the looks of it you have a 13 HP Vetus engine, but I\'m not quit sure if
this is a marinised Mitsubishi...

There should be two air inlet/outlets (follow the hoses):

1) one should be venting of the tank (preventing vacuum) and with the 1060
Vega this is originally on S.B. (both the tank and the overflow) check these
hoses carefully because this could be the source of the diesel fume inside.

2) your engine needs working air as well. This is usually done by the
transom vent and/or from the inside of the cockpit. It doesn\'t really matter
if these hoses are damaged as the engine will suck enough air anyhow. Typing
that I saw that there is quit a bit of isolating material in the engine
compartment... anyway, you will need 1 duct of around 10 centimeters dia to
get enough air to the engine.

This particular Vetus has engine -carterpan- expansion overpressure
protection. Good word for scrabble... This basically means that carter fumes
are led somewhere. Most times these are routed via a thin hose to the air
intake (easiest on a little engine) to be burned in the engine, but this
causes a black greasy transom (by the deposit) and sometimes owners lead
this little hose in a bottle or jar to settle down. Just check that this jar
is emptied once a year.

p.s. I think that you should give the entire engine bay, bilge and possibly
the engine a good cleanup with degreaser and get rid of a lot of fumes
inside.

p.p.s. as a rule. I normally try to keep the tank as full as possible, if
it\'s filled with diesel there is no chance for condensation and water in
your tank. Older diesel engines, including mine and yours (I mean older
design) don\'t like air in the diesel lines and \'de-airing\' a diesel is a
cumbersome process (not difficult, but dirty hands guaranteed and always on
the wrong moment)

The Vega\'s have by nature and design and internal ventilation duct that runs
under the P.S. bench from the cooking cabinet to the front cabin locker.
Supposedly there should be ventilation inside and keep your Vega cool
(according to the owners manual) I have serious doubts about this principle
but it\'s a nice gimmick.
Happy sailing,

Hello Sebastian:
If you're in the USA, you're required to have the exhaust vents; the one
as you say at
the very end of the boat should start with a vent hose in the bilge, and
have a vent-motor
at the other end. The other one, on the port side, has a hose connected
to the lowest compartment.
The starboard one can end inside the compartment.
Why the diesel smell? I don't know- I have a diesel engine but there is
a closed fuel system,
hence no diesel fumes can escape.
The vent for the diesel fuel tank runs along the inside to a vent on the
transom (a 1/2 to 3/4 inch hose)
usually located next to the stern light.
I have an electric gage for my tank- if you don't have one, it's easy to
install one.
Good luck- Wilhelm V257 VIKING

Dear Sebastian,

Congratulations on the purchase of your Vega 1060.

I have a short reply to you regarding the diesel tank. We keep it full at
all times, because after so many years (20 or more ) the diesel tanks
must contains sedements. I you run the tanks empty the sediments will
block your precious diesel oil filters.

As regards the diesel smell, I have the same problem. I keep the engine
as clean as possible. There is always some small leak in mine MD6A .
Probably some parts have become untight and repairs would cost a
fortune.

I have just returned from a week's trip in our Vega. We were moored in
Hoorn 25 yeards from the
VOC replica ship the Duyfken. In the evening there was theater in front
of the ship in the park.

We had a nice time there.

Happy sailing with your new (old) Vega.

Hi y'all (as "we" say here in the South),

thanks for all your replies and encouragement. I'll be off for a while,
but I'll be sure to try all your suggestions once I come back.

Happy sailing - Sebastian (Vega 1060)
