Ranger 620/621/622 Transducer Mounting Board

Our boards are made 1" thick black HDPE plastic and are Non-UV sensitive meaning they will never fade or crack from the sunlight. These boards will allow the use of a 1" long mounting screws (available on our website also.....sku# RTR515 ) which will make for a rock solid mounting! Also the boards have an added feature, the rear side of the board has a grooved inset perimeter...what this does is allows the installer to add a liberal amount of silicone or adhesive like 3M's 5200 to the center area and the silicone will fill the grove before pushing out the outer edge of the board making for a very clean install! The grove also creates a nice gasket for better water proofing!

RyTek Marine recommends the use of a high quality Pure Silicone ("Marine Grade" or 100%).   An installer can use 3M5200 or similar BUT Pure silicone has much better sealing properties and adheres perfectly to the HDPE for a life long leak free installation! AND is much easier to clean up if you have squeeze out!  With our transducer boards being applied and held by a mechanical fastener (Screws) 100% Silicone is the deal product to use for the installation of our transducer boards in both Fresh & Salt water!

#12 x 1.5" Stainless Steel screws are supplied for attaching the transducer board to the hull!

RyTek Marine recommends the use of 100% Silicone for all sealing surfaces when used with Fiberglass or Aluminum with our HDPE Transducer Boards and Flush Mounts.

Clean all surfaces with acetone before installation. Pre-drill holes with a "twist" drill bit slightly smaller than the screw thread diameter. (Please wear safety glasses). Test fit screw prior to installing mount by hand tightening with a screw driver. If the fit is to tight, back out and bore out the hole slightly and test fit again. Fill all thru holes with silicone prior to installing
screws. Hand tighten screws only and do not use a drill or impact driver....Stainless steel screws are brittle
