Moor Gauges

Does anyone have any experience with Moor instruments, particularly the depth sounder?

We need to replace our old Datamarine unit (and transducer), and the Moor unit looks like it would fit into the pod on our Merriman steering pedestal.

The Moor transducer is made to fit into the hull flush, so requires a beveled hole. Has anyone used the Moor unit with a different transducer, that fits into the hole the Datamarine transducer was in? That is a 2" hole with no bevel. The Datamarine transducer has a mushroom-type flange which sits outside the surface of the hull.

Our current Datamarine sounder is model S200DL.

Yes Dean, I replaced the original Standard Horizon depth last spring with the Moor unit,(also have their wind instrument). I have a fairing block and specified the long stem transducer,(bronze) which worked out fine.
For some reason when I went to order it from Defender they told me the unit had a puck trandsucer,(requires a larger hole) and was not available with any options. Checking with Moor, their website indicated that it was indeed available with optional transducers. I ordered it from Hamilton, there is a small additonal charge for the long stem. The stem has a 3/4" shank and the business end requires a 2" dia.recess in the fairing . I've had good luck with Moor, have used their stuff on other boats, they are easy to get a hold of and are made here-NY.

I've had two Moor depth sounders. The first one lasted about 6 years. I replaced it at the beginning of this season and its worked without a problem this entire season.

I don't know if 6 years is considered good for an instrument like that but that's my experience.

Warren, did you replace just the gauge, or also the transducer? If both, do you know which part failed?

Actually, I don't think the SH depth was 'original' to the boat but it lasted 12-15 yrs. D45 model. I had it bench tested and it worked fine. It's the transducers that more commonly fail. It's a toss up because a new bronze thru hull transducer is expensive, so a few more bucks an entire new one seems practical, especially if it's a swap out and a larger hole isn't required.
On a previous boat,(CD25) it had a Moor speed/distance log that stopped working, I contacted the company and shipped it to them. They replaced the circut board at no charge and sent it back.

Funny you should ask. First it was the thru hull transducer. I figured that out when I got a new transducer and simply hung it over the side..pulled the jack of the old transducer out of the back of the gauge where the transducer connects and plugged in the new transducer. The new transducer worked perfectly. The old was constantly erroneous. I alternated the two 4 or 5 times sitting at my mooring over 10 minutes and each time I got the same result. So, I figured I had it fixed. I also made sure that the surface of the old thru hull transducer wasn't fouled by paint or barnacles.

The next season however I started to see the gauge display looked like it was "burned out" The display blackened on the bottom and then read nothing. I'd turn it off, then back on. The display would come on for about 10 seconds and then blank out.

I got a whole new depth sounder (gauge + transducer). I installed that. Now I have a spare working transducer just in case.

By the way, I don't think the two failures (transducer 1st and the gauge months later) were related. I think it just burned out.

You may check Signet marine. I have the original Signet depth and speed instruments aboard and they still work at 28 years old. (Now I've cursed them.) Admittedly though with a few idiosyncrasies and the wind speed just stopped.

Dean,

If you would like instruments that will fit the cutouts of the old Datamarine instruments, well, Datamarine is still around but at DMI Marine, Inc. They repair old Datamarine instruments as well.

Their Phoenix System speed and depth instruments should fit where the old Corinthian instruments were installed. They sell the transducers too if you need new ones. They should fit the old thru-hulls as well. But I'd give them a call to make sure.

Thanks Cathy,

I have dealt with DMI, and I like them. I bought a new speed transducer from them in the past.

I had considered Moor, because then I would have newer technology. But because of the bevel issue, I have decided to just get a new DMI transducer and keep the Datamarine gauge, which DMI checked out for me and pronounced healthy.

Thanks all.

Try Air-Mar. They make transducers for most of the instrument trade.

If you use a fairing block, you should not use a filled nylon bodied transducer. Use bronze. Shearing the fairing block is a remote possibility, but rare events happen everyday.

Raymarine makes a tilted element transducer, I believe mine was the 12 degree model. I got rid of the "wood" fairing block a PO had installed. The transducer now sits flush to the hull. It works fine with my Moor digital depth sounder.

The Moor depth has a low water buzzer you can install. Problem is I never heard it over the roar of the engine. I had run aground (soft) this past summer while motoring, I shut the motor, and started to wonder what was that buzzing sound?

The Moor (speed, depth, wind) I installed are very good instruments for the price.

Now, I have what may be a really dim question (since there are no "dumb" questions).

I have an old depth finder that came with the boat. I've never been able to get it work. Will I need to replace the transducer if I install a new one? If there are variables what would I need to determine?

Warren Kaplan · Post by **Warren Kaplan** » Sep 30th, '10, 13:04

As I remember when I replaced my old analog depth sounder with a digital one, it worked with the old transducer.

I bought the Moor depth sounder because it was made by the same company that made the old one...although it had changed its name. It used to be EMS (Electro Marine Systems) and now its Moor. My old anaolg depth sounder was an EMS unit.

Anyway, I replaced the gauge and it worked with old transducer. Evenutually I had to replace the transducer as it quit.

So, if your broken analog is and EMS unit, the old transducer might still work.

Ray Garcia · Post by **Ray Garcia** » Sep 30th, '10, 13:25

Warren is right. The old transducer may work, obviously if the plug is the same. There is only one way to find out. There is no harm in trying. Though as Warren mentioned transducers do go bad time to time. The boat has to be in the water to test. Was that a dim sentence?

gates_cliff · Post by **gates_cliff** » Sep 30th, '10, 13:58

Well, when I do get a new depth finder I'll try it and post the results.

Thanks

and no, Ray, that was not a dim sentence as some folks might not realize the need to be in the water. Just in case though, my depth finder does not work with the boat in the water, never tried it out of the water!!!!!!
