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

Polyethelyene plate "eliminates unnecessary holes" ...so says the ad!
                         What do the famous boat and equipment manufacturers say about warranties?
                                    WARRANTY STATMENT LANGUAGE and disclaimers are all generally worded very similar.
             Remember  -  "MODIFICATION and ALTERATION"  - "EXCLUSIONS and LIMITATIONS"...it's in there!


                                                                         "In a nutshell..."
 Warranties are drafted to protect the mfrg. from you and you from yourself for installation damages created after the boat left the manufacturer.

                             Important Information you may have forgotten about:   
                               Transducer Mounting Boards - Transducer Mounting Plates
               Polyethelyene transducer mounting boards - Plastic transducer mounting blocks - Poly plastic cutting boards

                                * Possesses a very low surface energy...DYNES... (slick or waxy) and are resistent to adhesives
             * Polyethlyene cutting boards may not be UV stabilized and quickly deteriorate when exposed to outdoor elements

                                              Starboard™ is a high quality, UV stabilized, proprietary polyolefin thermoplastic
            *Starboard™ does not recommend using adhesives only without fasteners when fastening to itself or other substrates

   *Starboard™ has a very high thermal expansion rate (heat/cold)...it moves alot and can easily separate itself from an adhesive bond
             *Abrading (sanding), undercutting, "dovetailing", thread-cutting simply creates more surface area of the same material 
         (ex: Transducer mounting board glued to a hull which has been sitting in hot sun backed into cool water can easily "fracture" the bond = adhesive failure

"…that water intrusion or associated damages occurred from mounting this type of accessory (transducer), would the Ranger boat warranty accept responsibility and cover repairs or replacement for this type of claim upon determining that leaks actually occurred at the transducer mount screw holes?"

Response: Mon 4/27/09  "...Our factory warranty doesn’t cover any type of modification or alteration, which includes mounting transducers to the transom"....If water does leak into the screw holes...., this would not be covered by our warranty. Our warranty only covers manufactured defects in our workmanship".

 "The installation of a transom mounted fishfinder itself would not void the warranty, but any damage deemed to be caused by or resulting from its installation would not be covered under Ranger warranty. Hope this helps. Thanks again and let us know if we can be of further assistance".

Carolina Skiff "Modification and Alteration" Warranty Statement and Explanation
Stingray™ Boat Co. 

Warranty Information: (excerpt)

This Warranty does not cover the following:

“(d) Options and accessories installed after the boat was manufactured by STINGRAY, and/or any damage caused thereby:"
These famous well-respected companies provide the instructions to help you enjoy a problem-free boat for many years beyond the life of the warranty...
INQUIRY: "The attachment of aftermarket accessories, a transom-mounted transducer in this instance, would require drilling holes below the waterline for mechanical fasteners. Regardless of the method or attempt at sealing the screws and holes, would the Carolina Skiff warranty cover and accept responsibility for water intrusion between the hull and the floor and any associated damages of any sort upon determining that leaks actually occurred at those screw holes?"

Thank You,

- Transducer installation is justifiably intimidating to many installer/users. 
   Many dealers will not install transom transducers...the liability is simply too great
- Incorrect multi-attempt installations are common and result in many unnecessary screw-holes and, of course, boat damage
- Damage is always caused by “mechanical fastener” transom-transducer installations 
- The installation of “plastic cutting board-type mounts” create a damaging installation
- Common installations oftentimes create difficult or impossible transducer sounding adjustment capabilities
- Transducer upgrades almost always require a new set of damaging screw-holes

                       my boat that has 5 hours on it. Oh well crap happens".
09-06-2010   "Got my 597 installed and it is working great..."
09-06-2010   "Oh yeah, I guess I need to post why I want to move my transducer. I am loosing bottom anytime I am running over 7-8 mph."
09-08-2010   " I moved it down, but it was not enough so I need to drill some new holes. Not a big deal, I am going to go ahead and 
                        seal the old ones up with some marine tex and then drill some new ones.
09-12-2010   "I hate transducers. This thing is more of a PITA than it is worth. I mounted it to low this time and now I am spraying the side of 
                       my motor which is unacceptable imo. I am going to pull it to a local guy here and have him fix my gel coat and fix 
                       my holes and mount it for me I am done putting holes in my hull.  Oh well, lesson learned."   
Transducer Mounting Consequences
"We just purchased a new aluminum boat and was suggested by our friend to use the plastic board screwed to the transom to mount our transducer. Fortunately we found SternMate before we took his advice and have told others that they no longer have to drill holes in their boat to mount their transom transducer. SternMate works great! It looks like my friend will repair his screw holes and use a SternMate.

There are less expensive ways to mount a transducer on my boat, but I think I'll pass...I have seen them. SternMate is a tremendous value. You get exactly what you pay for, or you'll end up paying dearly later. 

Will SternMate be building a mount for two transducers? 

Jess
Lund boat owner

"G'day mate...Kudos to SternMate! I always enjoy buying the newest in fish-finding electronics. With each new one I buy, and I have bought several. I end up having to drill more holes in my boat for the new transducer because the hole patterns are always different and they are usually a chore to adjust properly too. My new boat will will definitely thank you for SternMate, and so will I". 

Bill and Eve

"My SternMate arrived last week and was easily installed. That is one stout, well made, piece of equipment . Before I began installing, I first made a simple repair to 4 transducer holes (a mistake I made when I mounted it in the wrong place the first time) and mounted SternMate right over the repairs. It looks great on my boat  too and it covered up my mess. SternMate makes my transducer very easy to adjust. StenMate is a great value, saves the aggravation of drilling holes below the waterline and simplifies my transducer adjustments. Its value is such a small price to pay to insure against costly leaking boat repairs which probably will occur  by mounting the old way. It's a great way to help me take better care of my boat too. Every one that uses a transducer should mount it on SternMate".

water in hull...transducer leak ? Ruined boat?
                                           A True Story...unfortunate, but typical

This is a narrated thread from a boating forum. The gentleman owns a new 2010 Carolina Skiff and has encountered a problem.  The "problem" is that he knew about SternMate. We expect there were sleepless nights, a whole lot of aggravation and  now installation damage expense he had liklely not counted on...not to mention miserable sounding performance from excellent electronics. Unfortunately, transducer installation experiences such as this are commonplace.  We trust that  his "local guy" is familiar with SternMate.

            There is an abundance of advice on "how to drill holes" in YOUR boat hull.         
It is amazing how so many will actually follow it and will skip right over All the Warnings
When your dealer offers to install your transom transducer, ask him for his written liability statement. You'll quickly learn how likely he will have lost all interest.
It Doesn't Have to Happen to You
This gentleman had an idea in a home improvement store..."found a corner segment of white vinyl roof gutter and, he says, " the light went on".
