We have an old standard horizon analog 45 series knotmeter. Through a series of events that we prefer not to bring up, the wire to the knotmeter transducer was clipped. That was three years ago. We tried a cheap splice 2 years ago and something a bit more professional last year. Neither splice did the trick. Unfortunately, the 45 series analog seems to be out of production, as are knotmeters in general from Standard.

Here is the question, since this is analog, will another transducer from an analog knotmeter work? There are only two wires, and there is a dampening knob. We race and have a gps for important stuff, the concern is more about speed relative to speed at other times during the race – therefore exact accuracy isn’t as important as consistency.

Next question, suppose we find an entire unit with the same size hole in our cabin coaming or secondarily, the answer to the above question is, sure it’ll work. Is there an industry standard to through hulls and transducers? Or will we need to seal up the old hole and drill a new one?

I replaced my Standard Horizon with a Raymarine. Used the same hole for the transducer. And no, I don't have the unit or transducer I removed.

I replaced my Signet with a Standard Horizon knotmeter and the transducer thru hulls were totally different animals that required patching the old hole and making a new one.

As for using a different transducer with your current display, I'm not so sure this would work since each brand probably produces its own unique pulse width determined by the paddlewheel geometry. Additionally, there may be voltage/resitance compatibilty issues between differing units as well.

If you only need a transducer, I would wait until one pops up on ebay or something so you can use the existing thru-hull. When I installed my new unit, I just gave away the Signet transducer.

You might have to bite the bullet and get a matching set.

Duane.
The guy at the instrument place i asked said that each manufacturer uses its own unique set of frequencies.

Or you could buy mine :) Its a SR Mariner, This is posted in the Forsale items along with the wind meter, I am asking 500.00 for both, all of the tranducers and wind guages are brand new from SR.

The DKL-5 is a digital Knot/Log indicator that reads boat speed from 0 - 19.99 knots full scale and has a total log to 9999.99 miles. This unit also features a (+/-) trim indicator and front mounted averaging adjustment. All Knot-meter and Knot/Log units include: Display, lower unit transmitter with 30' cable, thru-hull fitting, and dummy plug.

Below is a invoice for the thing I bought thru SR. Be fair, but as I stated in another thread this stuff is just sitting around in the garage. I can take detailed photo's if you want. and everything has been checked over and works.

SR Mariner CM-10 Combination Mast Unit N/A N/A 1 326.50 326.50
SR Mariner FRTR1 Lower Transmitter Unit for Knot/Log N/A N/A 1 46.76 46.76
SR Mariner FRDT1 Standard Depth Transducer N/A N/A 1 46.76 46.76
SR Mariner FRTH1 Thru-Hull Fitting w/Nut N/A N/A 2 7.79 15.58

Total Price: 493.20

I tried to get replacement plastic face covers for my Standard Horizon speed-log and depth sounder. None of that stuff is available any longer as SH is phazing out individual instruments in favor of GPS/chart plotters. If anyone has discovered an alternative for the instrument covers I would appreciate hearing from you.

Check the west marine catalog Al. I know they have some. They might not be Standard Horizon, but they would most likely fit.

CS - as much as I'd like the entire package, (especially wind) the depth meter is working fine and I can’t justify spending that much right now. The SR instruments - speedo with transducer is available at Defender for 106, I’m considering that right now.
