Sr Mariner Depth Sounder Manuals
Ok - I know the answer is 'replace the old analog system with new'.but I just purchased the boat and there are 100 things that need some kind of service, so before I spend $500 - $1500 on a new GPS / Depth sounder, please let me ask the question. I just purchased a CP-25, the depth gauge seemed to be working well on the first day of sailing (and during my brief sea trial); then started acting erratic. The needle was bouncing between 10 and 35 feet, in water that was less than 10.
I tried to adjust the 'gain' on the settings, but now the meter won't show over 10' of water. So, here is my question - does anyone have first hand experience with these instruments and have a suggestion for adjustment? I understand the manufacturer is still doing repairs, so does anyone know if the defect is in the display gauge, or could it be something wrong with the the through hull transducer? Thanks for your insight - JD. Hey JD: I thought that I was the only skipper with analog gauges! We have owned two 1986 C-27's and both have had SRMariner depth and knot/log instruments.

The original (new) C-27 actually had digital readouts, the current (used) C-27 had analog readouts. Like you when we first launched the boat 2 years ago it seemed like the depth meter was working, then like yours, it became erratic.
I tried everything that you tried with no success. The depth meter only worked kit seemed when the boat was at the dock. I could generally tell if the water was getting deeper or shallower, but not much else.
The knot/log instrument actually worked when the paddlewheel was barnacle free. So after two years of using the keel as a depth finder I just replaced both the instruments with Raymarine units, around $8-900. It is a relief to have accurate instruments. Of course the through hull fittings were not the same size but you can drill out the old ones and use the same holes to mount the new through hull fittings. The displays are not the same size, so the new displays are mounted in the same place on a piece of 1/2 inch Starbord covering the older larger holes.
As an added benefit the leaking in the head from the old instrument mountings is stopped. I did not appreciate the amount of water that was coming in until we replaced the old displays. This was not an urgent repair in that it did not compromise the safety of the boat and was not necessary to sail. So the replacement was put off till the CFO/Admiral gave the go ahead.
Good Luck regards charlie. Thanks Charlie. I use a hand held GPS for my positioning and map info, but I believe a depth sounder would make anchoring a little easier.
I called SR Mariner today, and left a message for them. Hopefully they will call me back. Even if the repair is $200, that is a better short term investment for me than doing a total system upgrade.
I have a knot meter on the boat as well, but the speed sensor wheel was pulled out and capped before I bought the boat. My GPS tells me speed, so that instrument will get chucked when I do my upgrade. I had an older unit similar to this on my CP23 and it worked fine. I am in the process of installing this new Hawkeye on my CP27. Less than $100.
The instrment is mounted, powered, and the transducer works through the hull beside the keel under the VBerth. The manufacturer suggests testing the location by putting the transducer in a baggie full of water in the spot where you will mount it. Seems to work fine like that, so next week I will epoxy it in place. Spending several hundred on a fancy one with network capabilities will have to come later.
At which point this will be a backup unit. I had an older unit similar to this on my CP23 and it worked fine.

Seems to work fine like that, so next week I will epoxy it in place. Spending several hundred on a fancy one with network capabilities will have to come later. At which point this will be a backup unit. My CP23 had a 2' round hole with the depth gauge mounted to the starboard side of the companionway door. My CP27 had a non-functional speed/temp gauge mounted down below the companionway to the right of the engine control panel. I just used that hole. The sensor is under the vberth in front, to the starboard side of where the keel forefoot is.
I had to move my baggie of water around to find a good spot. Too close to the keel it would not read. There's no hull penetraion, the transducer shoots through the hull. To close off a 4' hole, cut a piece of starboard or thin teak board bigger than the hole. Maybe square like a modern instrument display, and round the corners. The 2' hole goes in the middle of that.
Make one for the inside, one for the outside, and then use the new gauge display to sandwich them together. Use some sealant to prevent a leak on the outside. Msybe you could take the face of your old gauge, paint it, and use it as the external sandwich piece, depending on how it's made. It could be the bezel to cover the hole possibly. Of course plan B is to try to fill the hole with epoxy and gel coat and try to get it to match, then drill a new hole.not for me! If you want to temporarily mount it, leave the old unit in place and mount the new someplace else in an auto gauge pod.
I have one of these under my companionway steps to hold a fuel gauge so I don't have to crawl down in the aft compartment and try to read the meter in the top of the tank. There are many styles of these gauge pods. Yes, the internet can overwhelm us with options. See if an Academy or Bass Pro or Cabelas; whatever is near to you, has something on the shelf. Set your limit ($100150200) and sort them by range. Sadly though, they may have nothing. But if they do, take what they've got.
Forget the rest. And use the teak, or starboard, to make the bezel and fill the hole.
If you don't have a local store, make three selections of the variety and narrow it down. But there are some really good full on chartplotters, with transducers, available for under $700 too; but maybe that just muddies the water. Update - although the instructions say to NOT caulk the transducer to the hull (use epoxy), I've done it before and it worked fine.
This week I 'permanently' affixed the transducer inside the hull next to the keel, using a big wad of silicone caulk to just stick it down. It works fine, good readings from shallow to 80-90 feet deep. I (gently) grounded the keel nose first on a firm sand bank and sent my son overboard with a tape measure to measure actual water depth vs the sounder readings. It appears my mounting spot inside the CP 27 hull was about a foot below the waterline.
I prefer to read actual depth, vs depth under the keel, so it will be offset to display actual depth and an alarm at around 8 feet (CP 27 draws 3.5 feet).
DS150 Digital Depth Sounder (discontinued) 4.25 Inch square Digital Depth Sounder Capable of reading to 400 Feet, Meter or Fathoms. Has NMEA output that can be connected to the RP150 NMEA repeater or DS41 depth sounder for dual station operation off one transducer. NMEA output can also be connected to any STANDARD HORIZON GPS to show depth information on the plotter display.
GREAT DISPLAY The 150 SERIES features a high contrast LCD display with big black digits that are easy to read in any light condition. A rugged non-corrosive case features a curved lens that reduces glare. Backlighting provides clear images at night. SIMPLE OPERATION The 150 SERIES utilize intuitive controls that make it easy to take advantage of all the features. While each instrument can stand alone, the design is an integrated package.
The look and operation are consistent through all the pieces. WATERPROOF, AND BUILT TO TAKE A BEATING The front case, display and buttons are waterproof. Standard Horizon backs the 150 SERIES for a full year and then by our excellent Lifetime Flat Rate Service Program. UNCOMPLICATED INSTALLATION Installation is a breeze without the use of special tools. The full range of 150 SERIES square 4-inch instruments flush mount for custom looking installations. The case protrudes less than 1 inch from the bulkhead and only 1-inch into the surface, with a 1-' hole required for mounting.
Of course, the 150 SERIES instruments output reliable NMEA data, for interface with repeaters and other electronics. DS150 DEPTH SOUNDER Depth range is 400 feet, or equivalent in fathoms or meters.
The DS150 features visual and audible shallow, deep and anchor alarms. Prop or keel offset are part of the setup, which like the alarms are stored in a non-volatile memory for trouble free operation. Most importantly, a unique depth algorithm provides unmatched depth finding stability and reliability.
