SpcAlan1 I do not know if the 'speed' gauge is for wind speed or boat speed.. doesn't specify.

But since the boatspeed and depth is usually 1 transducer (?) that would indicate i have all 3. ?

hellosailor Alan, the boatspeed and depth transducers are often combined in one unit with one cable feeding them, so I would guess that IF your setup includes windspeed (always a sensor aloft by itself) and speed+depth, that one connection is for windspeed up the mast, while the other is for a thru-hull transducer for the pair.
Just an educated guess--since I don't know that rig. You'd have to check the wiring you found, see where it goes and what's left at the other end to try checking that. Although, if there's a marine electronics dealer near you that used to carry their stuff, sometimes asking for the oldest guy in the shop will bring about some hints. :-)

SpcAlan1 OK, i went out to the boa last night to 'trace' the wiring.

3 wires are coming out of the 'original box '.

1 - to transducer under cabinet in cabin - maybe depth ?
2 - running under the floor on port side - maybe for speed ? ( wind or boat ) ?
3 - To distribution panel

# 1 above -
the wire leaving the 'original' box and then go to another 3x3x3 box ( very small ). no labels, no ID#, nada... then leave this box and then to the transducer.. very strange.

The gauges only light up - no numbers for depth or speed.

teddier1 I love the boat you have hanging from the davits. What is it?

SpcAlan1 Ok, also I got these 2 separate 'boxes' with my 10 purchase of the gauge cluster.

( i know I need an account with a photo sharing site - but those are blocked by work )...

The top 'box' says 'power and digital lighting' - same as my original..

The second box says 'display mode ' - wind speed and depth' and 'depth alarm'.

Since the gauges light up when I plug in the serial plug and flip the nav breaker.. i am good there.

Now how/where do these hook up to the transducers ( that are under than cabinets in cabin ) ?

From what i can see now - my original box is wired to electrical panel and then the serial cable from it to the gauges, but where do the transducer wires come into play ? am I missing a 'piece' ?

SpcAlan1 Well I always say karma is a b*tch. But this is way over what I was expecting. I just cannot believe I found the original gauge at a boat yard sale.

Bilge pump - replaced with one that has an external float switch and wired to electrical panel with a toggle switch to run it. works great.

I also ( against my own will ) did buy the spinnaker sail from the yard sale as well.
35' long with 15 wide.... purple, blue, and white... haven't tried it, but will this weekend.

Minnewaska That must be the reward for some good clean living. Congrats.

How did you finally make out with the bilge pump?
04-25-2011 08:40 AM
SpcAlan1 Well here is another story...

Remember the IMBI Combi system I told you guys about?
Remember the wiring associated with the 'missing' parts that I was contemplating cutting and throwing away ( because the company went out of business in the early 80's ? ).

and remember the 'gaping hole' in the enclosure above the wheel ?


I went to a 'yard sale' for boats.. some random boating stuff put on by the marina and came upon this 'thing' that looked like it would fit the enclosure, that had the words IMBI on it.... Depth finder and speed gauge..

$ 10.00

Went to the boat, plugged in the serial cord, and placed it into the perfectly shaped enclosure... flipped the nav breaker.. and waaalaaa - IT WORKS.

What are the chances I would find this ?????? Please see member galleries....

this is unbelievable...

Minnewaska Float switch would not go below pump, but could cycle sooner. Maybe a pic of bilge.

Did you test in bucket?
04-07-2011 01:56 PM
SpcAlan1 I 'think' my bilge is the same depth - for what i can see in 3-4 different places under floor.

If I place a foot switch 'lower' than the pump, the pump will most likely NOT be in water high enough to pump - thus burning up the pump ?
