WFCYX Jumbo Stern Pad – Screwless Mounting Kit
Best for larger transducers used in high-end 3D scanning. The Jumbo Stern Pad measures 6.5″ x 4.75″ x 0.87″ and is designed to accommodate bigger transducers without screws. Features include the complete kit: one jumbo stern pad, scouring and prep pads, multiple adhesive and cable clip components, and push pins. Suitable for boaters who want a clean hull with a secure, screwless connection. A potential limitation is the size; ensure your transducer fits within the jumbo pad area before choosing.
SEAWORTHY INNOVATIONS Regular Stern Pad – USA-Made
Best for versatile, non-permanent setups on boats that benefit from easy, screwless mounting. The Regular Stern Pad was developed by Seaworthy Innovations (made in the USA) and claimed quick installation with a cure time of about 18 hours. Its design allows bottom painting and avoids hull screws or messy epoxies. The main caveat is the cure time; plan for a 15-minute install followed by the recommended cure period before use.
JAYEGT Transducer Mounting Board – 4.5″ x 3.5″
Best for small to medium devices, this 4.5″ x 3.5″ plate accepts easier, screwless installation without hull drilling. It’s designed for quick affixment with a 2–5 minute press and a 24–48 hour cure prior to mounting the transducer, ensuring a firm bond and better impact resistance. Consider this option if your transducer size and vessel surface call for a compact, non-permanent mount.
WFCYX Standard Stern Pad – 4.5″ x 3.5″
Best for standard transducers, this 4.5″ x 3.5″ stern pad offers a complete screwless mounting kit with essential accessories. It’s recommended to use a Jumbo pad for larger 3D scanning transducers. The kit emphasizes easy installation, simple maintenance, and non-permanent mounting that reduces hull modification. A limitation to note is that it is not designed for very large transducers.
JAYEGT Transducer Mounting Board – 4.5″ x 3.5″
Best for small to medium devices, this plate is designed for easy installation without drilling. It provides a secure bond after a curing period of 24–48 hours, helping resist wave impacts. Choose this if you prefer a compact option that minimizes hull alterations and is easy to remove if needed.
SEAWORTHY INNOVATIONS Regular Stern Pad – White USA-Made
Best for a white, non-screw, USA-made option with 3M VHB adhesive. This regular-size transducer mounting kit offers quick in-hull installation with a low-disruption profile and bottom-paint capability. The 18-hour cure time remains the key factor to factor into planning. The white finish can be easier to repaint or match boat hull colors if desired.
Buying Guide
What size should you choose? Measure your transducer and hull area to ensure the mounting pad provides adequate coverage without interfering with the hull curvature or fittings.
Do you need a screwless mount? If you want a non-penetrative, quick-install option, screwless designs reduce hull damage and simplify removal for maintenance or replacement.
Is UK/USA production important to you? Some options are USA-made and marketed as bottom-paint friendly; consider this if you plan long-term use in saltwater or tough conditions.
What about cure and install times? Many options require a cure period (often 18–48 hours). Plan around these times to ensure a solid bond before use.
Material and durability: Look for marine-grade materials (HDPE or equivalent) that resist salt, sun exposure, and impact. This reduces corrosion and wear over time.
Compatibility: Confirm your transducer’s size and mounting pattern align with the plate’s dimensions. Larger transducers may need jumbo pads; smaller units fit standard plates.
FAQ
- Q: Are screwless transducer mounts as durable as screwed mounts?
A: Screwless mounts use adhesive and surface prep to secure, offering solid performance when properly cured and installed on a clean, level surface. - Q: Do these mounts require drilling?
A: Most screwless kits do not require boat hull drilling, which preserves hull integrity and simplifies removal. - Q: How long before a transducer can be used after installation?
A: Cure times vary by kit, typically ranging from 15 minutes to 48 hours; always follow the manufacturer’s guidance for a proper cure. - Q: Can I paint the mounting pad or hull area after installation?
A: Some models are bottom-paintable; check the product notes and ensure you use appropriate marine paints compatible with the adhesive. - Q: Will these mounts fit all transducers?
A: They fit many common transducers, but verify dimensions (length, width, and mounting pattern) to ensure compatibility with your device. - Q: Is the pad resistant to saltwater and UV exposure?
A: Look for marine-grade materials and UV resistance for long-term durability in harsh boating environments.
