When you're pushing your boat through choppy waves or cruising at speed across open water, every piece of gear needs to perform without compromise. That's where the TotalScan Thru Hull Single Fairing Block steps in as a reliable upgrade or replacement. Designed specifically for TotalScan thru-hull transducers, this fairing block streamlines your setup, cuts through water resistance, and keeps your sonar readings crystal clear even in demanding conditions.
This fairing block isn't just a housing—it's engineered to hug the contours of your hull perfectly, minimizing drag and turbulence that can mess with transducer accuracy. Boat owners who've swapped in this block report sharper imaging from their StructureScan, CHIRP sonar, and DownScan capabilities, especially at higher speeds. Whether you're chasing trophy fish in rough offshore swells or navigating tight coastal inlets, it holds up against constant saltwater exposure, impacts from debris, and the grind of regular use.
Setting this up is straightforward, even if you're working solo in a slip. Start by dry-fitting the block to ensure alignment with your transducer. Apply marine sealant around the hull penetration, secure with the provided hardware, and fair it flush to your hull's deadrise angle for optimal flow. Pro tip: Sand the leading edge lightly for an even smoother profile, and always bed it properly to prevent leaks. Most installs take under an hour, getting you back on the water faster.
Common pitfalls to avoid? Over-tightening fasteners, which can crack the block, or skipping a fairing compound to blend it with the hull—both lead to premature wear. With proper prep, it'll outlast cheaper alternatives and maintain peak transducer performance season after season.
To maximize lifespan, inspect annually for barnacle buildup or hairline cracks, especially after winter storage. A quick wipe-down with a soft brush and mild soap keeps it looking sharp and functioning like new. Anglers in high-traffic areas swear by this block for holding zero adjustments through heavy use—no more recalibrating after every outing.
It's designed for TotalScan thru-hull transducers, fitting both M/H and L/H models perfectly without adapters.
Yes, its streamlined shape reduces water turbulence around the transducer, leading to clearer StructureScan and CHIRP images when planing.
Not at all—it's a bolt-on replacement using standard tools. Just ensure proper sealing to avoid water intrusion.
Absolutely, made from robust materials that stand up to corrosion, UV rays, and impacts in harsh marine environments.
It's optimized for typical V-hulls; minor angling adjustments during install accommodate most setups.
Rinse with freshwater after use, scrub gently for growth, and inspect for damage yearly—simple routine for longevity.
Out on the water, the gear you run could make all the difference. With our high-performance products proven in the harshest of environments, Simrad ® will get you there like no one else. We give you a comprehensive portfolio of precise and responsive technology for a complete experience.
