Transducer Mounting Board – JAYEGT Screwless Plate
Best for compact installations on small to medium transducers. This screwless mounting plate measures 4.5 x 3.5 x 0.75 inches and uses adhesive for secure bonding without hull drilling. Installation steps require a level, clean surface, adhesive application on one side, and a 24–48 hour cure for optimal strength. Best for boaters who want quick, hull-friendly mounting and minimal hull disruption. Limitation: not ideal for very large transducers due to size and weight considerations.
Transducer Mounting Board – JAYEGT Screwless Plate (Black)
Suitable for small-to-medium devices with the same 4.5 x 3.5 x 0.75 inch footprint. The screwless adhesive install minimizes hull penetration and simplifies re-positioning if needed. Best for boats where a quick, clean look matters. Caution: ensure the surface is level and clean to maximize adhesive strength; plan the final position before pressing.
Stern Pad – Black Standard Size (WFCYX)
Best for standard transducers and hulls that benefit from a compact, screwless mount. This 4.5 x 3.5 x 0.75 inch Stern Pad uses marine-grade adhesive and includes ancillary items like pads and anchors for secure mounting. Choose this for modest sized transducers and boats where a clean, crew-friendly install is desired. Limitation: not intended for larger 3D-scanning transducers without upgrading to jumbo-size pads.
Stern Pad – SEAWORTHY INNOVATIONS Standard
Best for quick installations with a Made in USA workflow and minimal hull disruption. This standard-size pad emphasizes ease of use, with an adhesive solution designed to handle marine conditions. Best for boaters who value a known brand and straightforward cure times. Limitation: the cure time can delay immediate use after install.
Stern Pad Jumbo – WFCYX
Better for large 3D scanning transducers due to its jumbo footprint (6.5 x 4.75 x 0.87 inches). It uses a robust adhesive kit and includes installation accessories. Best for boats carrying sizeable transducers that require extra surface area for a stable mount. Caution: larger surface may require careful surface prep to ensure maximum adhesive contact.
Stern Pad – SEAWORTHY INNOVATIONS Standard
Best for consistent results from a trusted brand with a short install footprint and compatible with standard transducers. Includes low-profile mounting and a curing period. Suitable for customers seeking a familiar fit from a brand with a history of screwless mounting solutions. Limitation: verify compatibility with very large transducers before purchase.
Buying Guide
What to consider when choosing a glue-on transducer mount:
- Transducer size compatibility: Match the mounting plate size to your transducer (standard 4.5″ x 3.5″ works for many small-to-medium transducers; jumbo pads suit large 3D scanning models).
- Adhesive performance: Ensure the kit includes a marine-grade adhesive and surface prep supplies (scouring pad, wipes, clips) for reliable bonding in wet environments.
- Surface preparation: Clean and level surfaces yield stronger adhesion and longer life. Plan the final position before applying adhesive.
- cure time: Some options require an extended cure period (up to 18–48 hours). Factor this into your installation window.
- Boat hull compatibility: Screwless plates minimize hull damage and painting needs. Consider whether bottom painting is available for your chosen model.
- Weight and stability: Larger pads distribute load better for bigger transducers and rougher seas. Choose jumbo pads if you expect heavy use or larger transducers.
- Attachment method: Adhesive-only mounts can be more forgiving on hulls but may be less forgiving on curved surfaces. Some kits include additional hardware for enhanced stability.
Frequently Asked Questions
- Do glue-on transducer mounts require hull drilling? No. They rely on marine adhesive or double-sided tape to attach the plate to the hull without drilling.
- How long does adhesive curing take before mounting the transducer? Most kits advise a cure window of 24–48 hours for stronger bonding; some options specify up to 18 hours before final mounting for larger pads.
- Are these mounts suitable for all transducers? They work best for small-to-medium transducers; jumbo pads are recommended for larger or 3D-scanning transducers.
- Can I bottom-paint a screwless transducer mount? Some screwless pads from SEAWORTHY INNOVATIONS are bottom-paintable; always verify with the product’s guidelines before painting.
- What if the adhesive fails in rough water? Larger pads with robust adhesive and proper surface prep reduce failure risk; ensure a long cure time and correct positioning during installation.
- Is re-positioning possible after initial adhesion? Once cured, some adhesives allow re-positioning with additional curing time, but the process may be challenging and is not guaranteed.
