Lowrance Kayak Scupper Transducer Mount

Upgrade your kayak fishing setup with a reliable way to secure your sonar transducer right where it counts. This scupper mount slips effortlessly into the drain holes of most sit-on-top kayaks, holding your Lowrance Skimmer transducer steady and fully submerged for crystal-clear underwater views. No drilling, no glue—just a quick setup that keeps you focused on the fish.

Why Kayak Anglers Choose This Scupper Mount

Kayak fishing demands gear that's tough, simple, and performs without fail. Traditional transducer mounts often mean compromising on boat stability or dealing with finicky adhesives that fail in saltwater. This mount changes that by using your kayak's existing scupper holes for a rock-solid hold. It's crafted from durable materials that resist corrosion, ensuring it withstands paddles through brackish bays, freshwater rivers, or coastal surf.

Positioned perfectly below the waterline, it maximizes sonar signal strength. You'll spot fish hugging the bottom, submerged timber, or drop-offs with pinpoint accuracy—essential for targeting species like redfish, bass, or walleye in tight spots where kayaks shine.

Seamless Compatibility with Lowrance Gear

• Works with HDS, Elite, Hook (formerly Mark), and X-Series Skimmer transducers
• Supports both 83/200 kHz standard sonar and 455/800 kHz DownScan Imaging models
• Fits earlier 1-inch 200 kHz transducers for legacy setups
• Black and white color options blend with most kayak hulls

Whether you're running a compact Elite unit for solo trips or a full HDS suite with networking, this mount integrates smoothly. It's a go-to for anglers upgrading from portable bags to fixed sonar without sacrificing kayak agility.

Step-by-Step Installation for Quick Deployments

Getting on the water fast is key in kayak fishing. Here's how to mount in under 10 minutes:

1. Select a scupper hole near the rear, ideally 2-3 inches wide (fits most popular models like Hobie, Native, and Old Town).
2. Slide the mount into the hole from below; it wedges securely with built-in tension arms.
3. Attach your Skimmer transducer using the included hardware—finger-tight plus a quarter-turn for vibration resistance.
4. Route cables along the hull interior, zip-tie as needed, and connect to your display.
5. Test in shallow water: Adjust angle slightly for optimal cone coverage.

Pro tip: In choppy conditions, add a cable strain relief to prevent pulls. This setup survives portages and trailering too—no removal required.

Real-World Performance Boosts

Anglers report sharper fish arches and structure detail compared to suction-cup or RAM-arm alternatives. Fully submerged placement cuts surface clutter, ideal for skinny water under 10 feet where kayaks excel. Pair it with Active Imaging or StructureScan for 360-degree awareness, turning your 'yak into a stealth fishing machine.

Durability shines in harsh environments: UV-stabilized plastics and stainless hardware laugh off sun, salt, and scrapes from loading/unloading.

Care Tips for Long-Term Reliability

Rinse with fresh water after every saltwater trip. Inspect tension arms seasonally and hand-tighten if needed. Store dry during off-seasons to prevent any buildup. With proper care, it delivers years of trouble-free service, backed by a solid manufacturer warranty.
