SternMate DepthfinderTransducer Mounting Bracket (plate) Components

Following C Marine Industries

There are any number of ways to mount the safety lanyard. The lanyard tab may be mounted as shown or under a transducer bracket mounting screw, if available. You may find a more suitable attachment for your particular installation.

The free end may be attached to the transom, motor mount or jackplate (see various photos herein).

SternMate™ is the best way to mount your transducer on your aluminum, fiberglass or wood boat

The Mounting Plate is engineered with 4 molded-in #10-32 screw inserts. Prior to adhering, the fixturing tab at the top of the Mounting Plate will assist with temporary mounting of the Housing onto the Mounting Plate. Use this while test fitting your transducer. The tab will also be utilized after the Mounting Plate has been adhered to your boat for subsequent adjustments of your transducer prior to fastening to the Housing. For the best transducer mounting location please refer to the instructions furnished by your electronics manufacturer. Confirm that the Mounting Plate will lie flat against your transom. Some arc in the transom behind the Mounting Plate is acceptable as our adhesive is a gap-filler. SternMate™ can be easily removed, without damage to your boat, should the occassion arise.

The Housing is designed with 4 horizontal slots upon which any combination may be used to mount your transducer bracket or other equipment. The Housing may be used solo (on boats with speeds that do not exceed 30 mph) and is fastened to the Mounting Plate with the provided ¾”x10x32. It may also be used in combination with the Set-back Plate fastened through the Housing to the Mounting Plate with the provided 1½”x10x32 screws. The 7/8”x10x32 screws and #10 nuts and Nut Holders will mount most transducer brackets to the Housing. DO NOT USE POWER TOOLS TO TIGHTEN SCREWS. NEVER SUBSTITUTE ANY OTHER LENGTH OF SCREW OR THREAD PATTERN TO FASTEN HOUSING OR SET-BACK PLATE TO THE MOUNTING PLATE. DO NOT OVER-TIGHTEN. PAY PARTICULAR ATTENTION TO THE SCREW SIZES FURNISHED, LENGTHS AND THEIR INTENDED USES.

"Ready for assembly"

The Set-back Plate™ is designed to fit into the Housing face recess and screw boss countersinks and mounted through to the Mounting Plate using the provided 1 ½”x10x32 screws. The Set-back Plate incorporates 5 horizontal slots, 4 of which are through-slots to the Housing. Any 5 of these slots may be used to mount most any transducer bracket utilizing the provided 1 ½”x10x32 screws, the #10 nuts and Nut Holders fastened thru to the back side of the Housing. All slots, except for the 4th slot, are designed to hold a #10 nut only. Should you find it necessary to use the bottom slot to mount your transducer, (machine screw/nut are not furnished) most likely it will be for a steep deadrise hull application when the transducer must be rotated to adjust parallel to the water. Use one screw in the bottom slot and fasten in 2 other places through the Housing for a secure "3-point" mount. In any case, secure your transducer in at least 2 (at least one machine screw on each side of your transducer bracket) places through the housing whether using the bottom Set-back Plate slot or not.

The Trim Snap may be snapped in place in the rectangular slot on the top side of the Housing and is purely decorative.

4 #10 Nut Holders are provided and are used on the inside of the Housing by placing the ears in any track or combination of tracks. The Nut Holder will seat flat and will grip for a secure hold. Place #10 nuts provided bottom first in the Nut Holders and assure that, when screw is tightened, threads extend beyond the nylon insert. Spares are included.

"My SternMate was such an easy installation. Like the instructions said, "take your time".

Everyone knows that transducers can be very difficult to adjust and change out having to drill new holes, but SternMate has taken all of that headache and worry away. It just is not worth ruining your boat to mount a transducer. Adjustments are easy and I am amazed at my ability to mark bottom at speed. Simply put, SternMate is such a unique product and every boater should be using one. It just makes good sense."

Boston Whaler Dauntless

"Captain" Chris I would like to thank you for an incredible product [SternMate] that actually does what is is supposed to do. The pictures are of my 1996 Boston Whaler Dauntless 15.

Well I've thoroughly tested the set-up and it has worked awesomely. From 1-2 and 2-3 foot chop the set-up has performed flawlessly, accurate depth soundings at fast water speeds without signal interruption. The set-up has been pounded in some rough chop down in the Florida Keyes and no adjustment was needed. The set-up has not encountered any signal interruptions traveling at speeds greater than 40 mph.

I very much enjoyed our conversation "Captain" Chris and your personal interest in your product's customer support."

"My SternMate is nearing a year since install and is working fabulous and still attached even after a mild sand bar grounding while boating through Biscayne Bay, Miami.

Ever since the picture [of my little Dauntless] appeared in your [Boat US] ad, she expects to be waxed and polished every other week. She’s “Star struck”. Thank you for a great design and product.

SternMate™ OEM Boding Adhesives are lab developed and Instron tested for us which dramatically exceeded our strict criteria to perform duty under adverse marine conditions. The precise molecular structure of our adhesives provide a “perfect marriage” bond to our proprietary SternMate™ thermoplastic mounting components and to your boat hull. We calculate precisely what the bond strength to your boat hull must be so that you do not have to wonder. Simple preparation procedures must be followed as prescribed. SternMate adhesives are thixotropic (won't flow on a vertical surface) and are gap-filling should there be a slight curvature of your boat transom. High speed testing and customer application have proved that our adhesives are easy to use and far exceed its demand. SternMate adhesives are designed specifically for the harshest of marine environments and the extremely high dynamic demands of the SternMate system. The tenacity and performance of our specially packaged adhesives pales in comparison with "off-the-shelf" homeowner” type glues, adhesives and epoxies you would find at the retail do-it-yourself stores where suitability for a particular job is left to captions on the package and guesswork. SternMate™ adhesives are also well suited for bonding our equipment under water. Testing has proved performance results unobtainable by most powerboats. Our “high speed” marine adhesives distribute stress evenly over the entire joined area rather than concentrating the stress at mechanical fastening (screws) points. SternMate may be easily removed with heat and without any hull damage whatsoever. Ask us!

Transducer installation and optimization comprise the most frequented "Troubleshooting" issues surrounding marine electronics

The Set-back Plate™ will be very useful in instances when the user’s hull may have a steep deadrise (deep V), including those which manufacturers of transducers do not recommend external transducer installation, simply because they will not properly reach the water. Some transducer brackets may be very short and restrict transducer reach for proper adjustment. The average transom “cant” rearward is approximately 14 deg. By installing SternMate, and more importantly, the installation of the “Set-back Plate(s)” to the Housing, the position of the transducer is “moved rearward and downward” now making difficult mounting and positioning of transom-transducers on many of these (deep V) hulls possible. An additional Set-back Plate may be stacked and is available as an option for greater aftward and/or downward reach. SternMate™ and the use of its Set-Back Plate (or an added 2nd optional Set-Back Plate), effectively moves the transducer properly aftward from the “trough” and into the rising displaced slipstream of water naturally created behind a fast moving boat. Elevating the transducer into the aftward rising slipstream employs a helpful unique corrective advantage toward optimizing your high speed sounding. By moving the transducer aftward and by raising it (oftentimes above the running surface of the hull) unnecessary drag, transducer chaos, turbulence, and that obnoxious rooster-tail found in old-style traditionally-taught transducer mounting instructions can be eliminated. Note: for the most effective use of SternMate ™, particularly on boats which travel at speeds of 30+ mph, we always recommend using the included Set-Back Plate.

SternMate step-lad’r™

Optional Accessories for your SternMate™ System

SternMate™ Kit Components...the "RULES" have changed

Easily mount multiple transducers on SternMate. Functions also to move your high speed transducer aft while you enjoy the benefits of your imaging transducer installed nearby.

The SternMate step-lad’r™ is a muti-functional addition to your SternMate system and your SternMateDUO. Mount your tranducers high or low (gain up to approx. 6") to best suit your unique installation...it's adjustable, it slides and its universal. The "step-lad'r" can be "flipped" top to bottom for greater height or greater depth and gives you the same unique SetBack advantage as the SetBack Plate that comes with your kit for a precision high speed sounding. You can even add the "step-lad'r" to your SetBack Plate. By using your SternMate transducer mounting system, you can easily mount your high speed transducer on those difficult to impossible "stepped transom" (set-back transom) boat hulls and reach the water like you have never been able to do before. The "step-lad'r" can also be used with your SternMateDuo on those "set-back" transoms, or any transom for that matter, to mount your imaging transducer and your high speed transducer. Your SternMate step-lad'r optional accessory allows you to mount your SternMate either parallel to the water or on the dearise (no matter what degree deadrise hull) and you can use your favorite transducer...its all up to you! ..the Rules have changed
