How are tachometers normally hooked up on the MD6A?
Any existing provisions for this like a prox/magnetic sensor mount?

Theres a lot on this topic if you search the archives.

Hi All
Can anyone tell me where the hole at the bottom of the bilge is? (the
one that allows the bilge to drain down into the hollow part of the
keel and from there out via the keel drain plug) I cannot see or feel
where the hole is in my bilge.
It looks like a previous owner may have spread some resin over the
forward part of the bilge - presumably to stop the bilge water going
down into the hollow part of the keel. However he didn't do a
particularly good job because when I drilled out the keel drain plug
(it was impossible to undo) water came out and the level in the bilge
dropped very very slowly, so I know there must be some exit from the
bilge. There was not much pressure behind the waste so I suspect the
original hole is partly blocked by the resin.

I need to open it up and that means locating it as accurately as
possible, so can anyone tell me:

Where is the hole? - is it in the sidewalls, the forward 'bulkhead'or
the sole of the bilge?
If not right at the bottom, how far up?
If not right up against the forward 'bulkhead', how far back?
Port or Starboard side?
Does the hole point down or sideways?
Any idea what size the original hole was?

Actual measurement may be difficult to obtain so a rough idea would be
fine. As you know, working flat on your stomach with your arm down the
bilge is not the easiest of exercises, so any help would be
appreciated - and yes, before anyone asks, I DO want to be able to
drain the bilge through the keel drain - I'm fed up with using a scoop
and sponge.

Thanks

The sensor on the MD7A, which I believe is nearly the same engine
as the 6A but a larger bore, is located on the lower port side, aft
and a bit lower than the oil filter. This is from memory as I don't
have the manual here, but that general area. It resembles a plug with
an electrical contact. It is a magnetic switch, and it is pricey, I
think I was quoted $170.00 or so, from the dealer. I have been
reluctant to get a new one until I am certain it is the switch that is
bad, and can't be repaired. Roy, if you have success with yours, I
would like to know it.

I use a wet/dry shop vac myself. I have one small vac dedicated to just wet.
It does more than just pickup water as it will pick up little bits of debris
that have worked their way down. The hose is plenty long enough. Of course
you have to life the shop vac "bucket" out to empty it, but get a small one
and it isn't that heavy.

Personally I find the idea of a drain hole useless since my boat is in the
water year around and the shop vac works far better than cracking a drain
plug in the yard (not to forget the problems that can go with having yet
another hole below the waterline). Please don't flame me on this, if you
like your drain plug - drain on!!! Most boats built in this country don't
have these that I know of.

Hi David
I've used (very) cheap disposable babies' nappies (diapers for N

Just drop them down and agitate a bit with a boathook (or whatever) and

Repeat until bilge is dry or nappies/diapers are all gone...

My bilge pump has input pipe about 2 inches/4cm in diameter so last inch

As usual, the following is based on my limited Vega experience and
may be completely out in left field.

On Sin Tacha the bilge drain plug is at the low point of the
bilge, on the port side wall, and drains out through the port side of
the keel.
On the outside of my keel, down below the bilge drain plug, right
near the bottom of the keel, is a 1/4" machine screw that can be
removed to drain the hollow cavity in the keel, below bilge level.

I don't think there's supposed to be a drain from the bilge bottom
inside the boat, down into the hollow keel cavity. Stricly speaking,
that cavity should be dry, but never is. There always seems to be a
bit of seepage from "somewhere" to get it wet. I would think the last
thing you want to do is direct bilge water down into that hollow part
of the keel.

Hope this helps, Dave.

I did an archive search before writing and found lots on the Keel
drain plug but nothing on the location of the Bilge drain hole.

As I am sure most owners know, the Keel has a void area just in front
of the rudder that allows water to drain down from the bilge into this
area and eventually out of the boat when on the hard via the keel
drain plug at the bottom starboard side of the keel.

My difficulty is that a previous owner tried to block the bilge drain
hole with resin but it didn't work, so water still gets down into the
keel void. I want to locate this BILGE drain hole and open it up so I
can send soapy water down into the keel void to remove any accumulated
crud then wash it out before putting the keel drain plug back in, but
I can't do this with the partialy blocked hole in the bilge as the
flow is much too slow, and I cannot identify where the hole was
originally because of the resin! I could drill a new hole of course,
but I would prefer to open up the original one if possible.

Hi Peter

Thanks for the info. unfortunately my keel drain plug is on the
starboard side so the bilge drain hole may vary with the position of
the keel drain plug - anyone know??

I presume the keel drain system was designed to allow the bilge to be
emptied when the top of the bilge space was blocked off by the
original petrol tank and you couldn't get down there to clean/dry it out.

Cheers

Hi John

Yes I've used them too but this time I wanted to clean out the bilge
with soap and water prior to painting so had to get down on my stomach
- Boy am I suffering this morning!

David, it sounds like the interior of the keel has been modified. I
don't think Vega's were originally built with a glassed-off panel that
makes it impossible to access the bottom of the bilge where the drain
plug is located etc. How would one get a bilge pump down there, or
access it clean it out? How would one know when to empty it etc etc?
Can you take a photo of the set up and post it for a better idea what
you're dealing with? Thanks, Trev (V2915 - Mystic Rose)

Hi:
I'm reading a lot about the bilge drain etc.; so I add my experience

My Vega is # 257, I own her since... I think it was 1976 when I bought her. There never was a fuel tank or anyrhing in the bilge- there is just a big hole. On the bottom of the hole (starboard side) is a drain which is very important when the boat is on the dry in freezing areas. I used it when my boat was in the Great Lakes, though since I'm now in South Florida I have the boat 365 days in the water, I plugged the hole (but it can be unplugged if necessary).

I have a bilge pump with an automatic float switch in the bottom of the bilge. There also is the hose for the manual bilge (outlet near the rudder). I hardly ever get any water into the bilge, but there is always some water because the float switch is set high enough to make room for the water that comes back (from the hose) when the pumpe stops- otherwise the pump would run on and on most of the time. From time to time I clean out the bilge with a sponge- once or twice a year- it's a dirty job- because there is dust, dirt, and whatever mixed in the water (about a quart or 1 liter) that gets down into the bilge.

I read also about water getting "into" the keel. I don't understand that, because in my boat there are no voids below that grain plug- where any water can get out when the boat is out of the water.

Thanks Craig.

I have an aftermarket automotive alternator mounted on the engine, and sometimes I've read, they have an extra wire or something that can be hooked to a tach. So that's another option.

I'll be over at the boat in a couple of days, and I will look for the magnetic mount as well as check out the alternator.

Hi Peter

FOUND IT!
Hidden by the cable from the log spinner I spotted it when moving the
cable to clean the sides. Unexpectedly my drain hole is at the aft end
of the bilge, about 10cms (4") fo'ard the bottom step and about 1.5cm
(1/2") above the bilge sole on the starboard side. It seems to be a
brass skin fitting that stands proud of the side wall. Because of its
location (I'm 6'3" and have pretty long arms but can barely manage to
touch it), I wonder if the keel was a separate molding or maybe Albin
Marin had a tame Troll they sent down there to fit it! Anyway bang
goes my plan to fit a removable plug to stop water going down into the
keel void.

I was quite surprised at the position of the drain hole as, with the
boat sitting on its keel on the hard I still had about 7cms (3") of
liquid crud in the bilge that must have been lower than the outlet
into the keel void - I had assumed the outlet would be at the lowest
point of the bilge which is close to the forward bilge bulkhead, and
was looking in the wrong place. Anyway this information may be helpful
to anyone else with a series II and a hull number close to mine who
wants to locate their drain - not that there is much that can be done
with it except poke a bent piece of wire through the hole to clear any
blockage.

I agree it doesn't sound too clever having a skin fitting outlet some
1.2m below the waterline that would sink the boat if it failed but I
had to drill out the keel plug on mine because I couldn't shift it
even with an impact driver, and found the brass plug to be about 5mm
thick so it is pretty substantial.

All my reading suggests that all Vegas were fitted with these keel
drain points, even after they relocated the petrol tank and that -
probably - all had a open drain hole between the bilge and the keel
void - although many may have been glassed over for safety by now.

Thanks to everyone who replied

Hi Wilhelm

I think there is some misunderstanding here. What I call the 'bilge'
is the area I can look down into when I lift the wood aft cabin sole
cover. When clean and dry I can both see the bottom and put my arm
down there and touch it. Below this, and totally inaccesable, is a
void in the keel for'ard of the rudder. At the bottom of this void on
the outside of the keel is a skin fitting with a screw-in plug that
can be removed and allows any water that has migrated into the void to
escape.

As far as I am aware water can only enter this void from the bilge, so
there has to be a hole between the bilge and the void and it was this
hole I was looking for. As you may have read elsewhere, I found it today.

Cheers

David

Hi David

You have a Series II Vega according to your vega Number (V1696). There should be a completely empty bilge down to the bilge drain. It sounds like a previous owner has glassed a cover over the bottom of your bilge. I suggest you drill a nice big hole or remove the glassed-in cover.

Cheers

Hi Everyone

Is there a prize for being the dumbest member of this forum? because I
have just won it - hands down!

Somehow I had it fixed in my mind that there is a bilge AND a void in
the keel - not that they are one and the same thing - so I have been
looking for something that doesn't exist!

My apologies for confusing everyone who tried to help. Put it down to
old age, my wife does.

Well, technically there IS a bilge and a void, the void being a part
of the bilge blocked off with a partition because ... who knows why?

What I'm getting from all this bilge talk is that the later series
Diesel Vegas' bilge is open to the bottom of the keel, and the fuel
tank is located down where the early Vega foam area is. Maybe they
blocked off the early models so you could retrieve dropped items more
easily.
I guess I'll have to wait for the PNW Rendezvous to see a late model
bilge in person!
