Black Jumbo Size Stern Pad – 6.5″ x 4.75″ / Screwless Mount
Best for larger 3D scanning transducers, this jumbo Stern Pad offers a screwless mounting surface with marine-grade durability. The kit includes a jumbo stern pad, scouring pad, prep pad, cable clips, 3M adhesives, and push pins, enabling a clean, OEM-like finish. It is suited for buyers who need a robust, no-drill solution on bigger transducers, with a focus on fast installation and long-term seal integrity.
Who this is for: boaters mounting large transducers, skippers seeking a low-hassle, low-profile install, and anglers requiring a strong foundation for frequent launches. Why selected: it pairs a broad footprint with reliable adhesive-backed mounting, reducing hull penetration and maintenance.
Potential limitation: for very small or lightweight transducers, this jumbo pad may be oversized and not offer optimal alignment. If your device is smaller than standard, consider the standard pad option.
Stern Pad by SEAWORTHY INNOVATIONS – Regular Size, Black
This regular-size option emphasizes ease of installation with a screwless design and genuine 3M VHB adhesive. It is optimized for quick setups, with an emphasis on simple, clean adhesion rather than hull drilling. It’s a strong choice for users prioritizing a USA-made product and a straightforward install, including bottom-paint compatibility.
Who this is for: recreational boaters needing a dependable, efficient mount for mid-sized transducers. Why selected: it minimizes hull disruption while delivering solid adhesion and long-term stability.
Limitation: cure times can extend to days; plan for the adhesive to fully set before testing transducer performance.
Transducer Mounting Board – 4.5″ x 3.5″ Standard (Black)
This plate is designed for small to medium devices and avoids hull drilling. It features a screwless design with easy installation, plus a protective build to guard the transducer and boat hull. The setup requires proper surface preparation and a curing window for best adhesion. It’s ideal when you want minimal hull modifications and a clean transition from mount to transducer.
Who this is for: kayaks, small boats, or pontoons with mid-range transducers. Why selected: straightforward, no-drill mounting that protects the transducer and hull and reduces installation time.
Caution: not suitable for very large transducers. If you own a larger device, opt for jumbo or larger mounting options.
Transducer Mounting Board – 4.5″ x 3.5″ Standard (Black)
This option mirrors the standard size plate with screwless mounting and no hull drilling. It emphasizes easy installation, with a recommended two-step cure approach to maximize adhesion. It’s best for small to medium devices where quick setup and hull preservation are priorities.
Who this is for: users needing a simple, low-impact mount on small to mid-size boats. Why selected: consistent, easy-to-follow installation that minimizes hull modifications while delivering reliable support.
Limitation: not recommended for very large transducers, which may require jumbo pads or larger mounting boards.
Stern Pad by SEAWORTHY INNOVATIONS – White Regular Size
The white, regular-size Stern Pad offers the same screwless mounting philosophy and 3M VHB adhesive as the black variant. It is designed for clean, visually unobtrusive installations on exposed hulls and is bottom-paint compatible. The kit supports reliable adhesion with a curing timeline similar to its black counterpart.
Who this is for: boaters who prefer a white mounting surface for visibility or aesthetic reasons. Why selected: provides a consistent, durable mounting solution with a different color option to match hull styling.
Limitation: color choice may influence visibility of debris or residue during maintenance, not a functional drawback but a consideration for clean hull appearance.
Buying Guide — Key Purchase Considerations
- Transducer size compatibility: Choose Jumbo for large transducers and Standard for mid- or small-sized models. Avoid mismatches to ensure proper fit and seal.
- Installation method: Screwless systems reduce hull penetration and hull maintenance. Ensure surface is clean and dry for optimal adhesive bonding.
- Adhesive type and cure time: 3M VHB adhesives are common; plan for curing before exposing the transducer to waves to maximize adhesion.
- Hull compatibility: Some variants allow bottom painting; verify whether your boat’s paint type is compatible with the adhesive bond and curing process.
- Material durability: Marine-grade boards resist UV exposure, saltwater, and physical impacts. This is important for long-term reliability on exposed transom areas.
- Ease of removal or replacement: screwless pads simplify removal but ensure you understand the adhesive’s removal process to avoid hull damage.
Frequently Asked Questions
- What is a screwless transducer mounting kit? – It uses adhesive-backed pads or mounting boards to attach a transducer without drilling holes in the hull.
- Can I use a standard size pad for a large transducer? – No. Large transducers typically require jumbo or larger mounting options for proper fit and performance.
- Do these kits require cure time before use? – Yes. Adhesives often require a cure period to achieve maximum bonding strength.
- Are these kits suitable for bottom painting? – Many are; confirm with the product description to ensure the adhesive and mounting plate can be painted.
- Which kit is best for kayaks or small boats? – Standard size, screwless mounting boards are usually best for small vessels due to their compact footprint and ease of installation.
- Is hull drilling ever necessary? – The screwless designs eliminate drilling; if your mounting needs exceed their capacity, a traditional mounting method may be required.
