Bert’s Custom Tackle American Made Transducer Mounting Board
The mounting board offers a clean, secure surface for installing transducers and other electronics without drilling the transom. Best for boats where a robust, durable mounting plate is needed to support multiple devices. The marine-grade polymer construction resists cracking, warping, and UV damage—an important factor in harsh marine environments.
Who it’s best for: Boat owners who want a reliable, non-drilling solution for multi-device installations on larger or older hulls where added surface protection matters.
Why selected: This board provides a stable platform that protects the transom while enabling multiple installations and easy adjustments, reducing wear on the hull.
Limitations to note: It may be overkill for very small craft or single-transducer setups where space is extremely tight.
Bert’s Custom Tackle USA-Made Transducer Mounting Board
Designed for smaller boats or constrained spaces, this 6″ design focuses on compact, secure mounting without drilling. Its heavy-duty marine-grade polymer resists cracking and warping while withstanding UV exposure. The product suits single transducer setups or installations where space is at a premium.
Who it’s best for: Small- to mid-sized boats where a discrete, screwless mount is preferred and room for a larger plate is unavailable.
Why selected: The compact footprint makes it easier to position transducers in tight spots, while still protecting the hull and allowing repeat installations.
Limitations to note: The smaller plate may not accommodate very large or multiple transducers as easily as bigger boards.
Stern Pad Jumbo Black – Screwless Transducer Mount
This jumbo adhesive-based mounting pad is designed for larger 3D scan transducers and other sizable electronics. It avoids hull penetration and includes a quick installation pathway with a longer cure time to achieve a strong bond. It is recommended for boats that require adhesive mounting with minimal hull alterations.
Who it’s best for: Boats needing an adhesive solution capable of supporting larger transducers over larger surface areas.
Why selected: The giant pad provides substantial surface area for load distribution, reducing stress on the transducer and hull.
Limitations to note: Requires 24 hours cure time; immediate use is not possible right after installation.
Saillong Transducer Mounting Plate Kit
This complete kit includes a mounting plate, cleaning wipe, scouring pad, and cable clips. The plate uses a 2mm adhesive backing for a strong bond and provides a large, forgiving area for securing a transducer without drilling. The polypropylene material offers corrosion resistance and a clean surface finish.
Who it’s best for: Budget-conscious buyers who want a full adhesive mounting kit with handy accessories for quick setup.
Why selected: The all-in-one package reduces setup steps and provides everything needed for a non-drill transducer mount.
Limitations to note: Delays can occur if adhesive cure time isn’t properly observed; ensure proper surface preparation for best results.
Stern Pad – Standard Size White
The standard Stern Pad provides a screwless mounting solution for smaller transducers, with the advantage of being bottom-paint friendly. The adhesive-based approach minimizes hull modification and supports straightforward removal when needed.
Who it’s best for: Boat owners seeking a clean, light-duty adhesive mount for small to medium transducers on hulls that require minimal alteration.
Why selected: It balances ease of installation with a dependable bond, making it a practical choice for casual anglers and weekend boaters.
Limitations to note: Not recommended for very large transducers or heavy-duty use where high vibration is expected over time.
Buying Guide: Key Considerations for Drilling-Free Transducer Mounts
- Transducer size and weight: Larger transducers require broader mounting surfaces to distribute stress and avoid tipping or misalignment.
- Surface compatibility: Check hull material and finish; some adhesives perform better on gel coats and non-porous surfaces than on painted or textured surfaces.
- Adhesive cure time: Most screwless mounts need a curing window before use. Plan installation with a waiting period to ensure a strong bond.
- Water exposure and UV resistance: Marine environments demand durable, UV-stable polymers and adhesives to prevent cracking and degradation.
- Removability and reusability: If you expect to relocate transducers, choose mounts designed for repeated mounting and removal without damaging the hull.
- Multiple transducers: For setups with more than one transducer, prioritize mounting boards or large adhesive pads that offer multiple attachment points without drilling.
- Bottom painting compatibility: Some adhesive pads can be bottom-painted; verify if the product supports this for your boat’s aesthetics and needs.
FAQ
- Can I install a transducer mount without drilling on any hull?
= Yes, screwless mounting pads and adhesive boards exist for many transducers, but success depends on hull material, transducer size, and adhesive strength. - How long does adhesive-backed mounting need to cure?
= Cure time varies by product; commonly 18–24 hours or longer in marine environments to reach maximum bond strength. - Are these mounts suitable for high-speed boating?
= High-speed use requires stable, well-bonded surfaces; ensure the chosen product supports the transducer’s weight and vibration. - Can I remove these mounts without damaging the hull?
= Most screwless options are designed for removal, but some adhesive residues may require cleaning; follow the product’s removal instructions. - Will these mounts tolerate saltwater exposure?
= Yes, when made from marine-grade polymers and corrosion-resistant adhesives, but check UV and salt tolerance per product specs. - Do these kits include everything needed for installation?
= Some kits include mounting plates, wipes, and clips; others may require separate purchase of adhesive and cleaning supplies.
