Mounting Options

The StructureScan transducer can be mounted on the transom, jackplate, step, trolling motor or directly to your boat’s hull.

When mounting it directly to the hull, you must purchase a high-quality, marine grade aboveor below-waterline sealant/adhesive compound.

Use the following table to determine which mounting option is best suited to your boat/installation preferences.

StructureScan Transducer Mounts

		• Keeps transducer in the water when the boat is
		on plane, allowing you to track bottom at high
	Transom Mount	speeds
		• Transducer angle can be adjusted so it is parallel
	(Page 6)
		with the water
		• Transducer more likely to collide with obstructions
		in the water and adds drag to the boat
		• Transducer is not in the water when boat is on
		plane; protects transducer and prevents drag
		from transducer
	Jackplate Mount	• Transducer angle can be adjusted so it is parallel
	(Page 7)	with the water
		• Allows you to mount transducer without drilling
		holes in your boat
		• Does not track bottom when boat is on plane
		• Transducer is not in the water when boat is on
		plane; protects transducer and prevents drag
	Step Mount	from transducer
	(Page 8)	• Transducer angle can be adjusted so it is parallel
		with the water
		• Does not track bottom when boat is on plane
		• Transducer is not in the water when boat is on
		plane
	Direct Mount/Step	• Protects transducer and prevents drag from

	(Page 9)	• Transducer angle can not be adjusted so it
		is parallel with the water
		• Does not track bottom when boat is on plane
		• Allows you to scan areas by moving trolling
	Trolling Motor Mount	motor left/’right
	(Sold separately)	• Can only be used when trolling motor is in the

Bracket and Transducer assembly

The StructureScan bracket comes with four washers, two bolts and two nuts.

If you plan to mount the StructureScan transducer directly to the step (Step Mount) or on the trolling motor, you do not need to assemble the bracket.
