Bert’s Custom Tackle Heavy-Duty Mounting Board
This marine-grade polymer mounting board offers a clean and secure surface for fish finders, speed sensors, or other marine electronics. Crafted in the USA, it is designed to resist cracking, warping, and UV damage in harsh marine environments. Its key feature is enabling multiple installations or adjustments without directly drilling into your aluminum boat’s transom, thus protecting your boat’s integrity. The board’s durability ensures long-term resilience, making it suitable for varied transducer sizes and applications.
BZBMGMO Transom Transducer Mounting Board Plate With Stainless Screws
This mounting plate measures 3.5″ x 4.5″ x 13/16” and comes with 316 marine-grade stainless steel screws. Made of durable PVC, it requires applying a high-quality marine adhesive on the back before mounting. The recommended installation method includes drilling a pilot hole, coating screws with adhesive, and sealing with caulk around both the board and screw holes for waterproof protection. This approach ensures stability and protects the boat’s transom while providing a reliable mounting base.
HDWGGD UV Resistant Marine-Grade Transducer Mounting Plate (White)
This sturdy transducer mounting plate boasts a solid marine-grade polythene construction that won’t warp, corrode, or lose performance over time. With pre-drilled holes and included stainless steel screws, it offers an easy installation process. Applying marine adhesive can maximize seal integrity and protect against water intrusion. Its thickness of 0.8 inches supports various transducer sizes securely. This plate also helps cover old mounting holes, eliminating extra damage to your aluminum boat.
Saillong No-Drill Transducer Mounting Plate Kit With Adhesive
This innovative mounting plate kit is perfect for aluminum boats because it requires no drilling. The high-hardness polypropylene plate features a 2mm-thick adhesive backing, ensuring a strong, durable bond to the hull. The kit includes cleaning wipes and cable clips for a full installation package. Measuring 4.33″ x 3.54″ x 0.98″ and corrosion resistant, it maintains reliability in marine conditions while protecting your boat from potential damage caused by screws or holes.
Attwood UV-Resistant Marine-Grade Transducer Mounting Plate
Crafted from premium marine-grade polymer, the Attwood mounting plate is highly resistant to UV rays and corrosion. It offers a simple mounting process that requires only two screws, providing a secure base without the risk of warping over time. The plate’s robust build is suited for aluminum boats needing a reliable and stable surface for transducer installation. This model caters to users looking for longevity and minimal maintenance.
Buying Guide For The Best Transducer Mounting Plates
Material Durability And UV Resistance
Looking for mounting plates crafted from marine-grade polymers, polythene, or polypropylene is important as these materials resist cracking, warping, and UV damage. Aluminum boats face exposure to sun and water, so UV-resistant materials extend mount lifespan and maintain mounting integrity.
Installation Method: Drill vs. Adhesive
Some mounting plates require drilling pilot holes and using marine-grade screws sealed with adhesive and caulking, which ensures a secure attachment. Others offer adhesive-backed no-drill installation, reducing damage risk but requiring cure time for the adhesive to set. Consider boat hull material and your comfort with drilling when choosing.
Size And Thickness Compatibility
Ensure the mounting plate size matches your transducer’s base and that thickness supports a flush, stable fit. Plates around 3.5” x 4.5” and 0.75” to 0.98” thickness suit most small to medium transducers, while larger units may require custom solutions.
Corrosion Resistance And Marine Environment Suitability
Saltwater exposure demands corrosion-resistant hardware such as 316 marine-grade stainless steel screws. Marine-grade polymers also add protection against corrosion and harsh elements, preserving both plate and boat surface.
Repeat Mounting And Adjustment Capability
Mounting plates that allow multiple installations or transducer adjustments without damaging the boat are ideal. They cover old holes and facilitate upgrades, providing flexibility for future electronics changes without compromising boat integrity.
Additional Accessories And Complete Kits
Some mounting plates come as kits with cleaning wipes, cable clips, or scouring pads for better surface prep and cleaner, more secure installations. These extras can simplify the process and improve bond strength.
