Airmar 164WR-3 Double Handle Transducer Wrench

The Airmar 164WR-3 is a double handle transducer wrench for tightening the hull nut on bronze low-profile thru-hull transducers. It fits the B164, SS164, B175C and SS264. Holding the hull nut steady with the right tool makes installation much easier and protects the nut.

The wrench is 3/16 inch thick mild steel. The two handles give you leverage and control in a tight bilge. Mild steel can be bent or modified to reach awkward installation spots.

It's typically used with the Airmar 175WR-4 housing wrench, which holds the transducer housing while you turn the nut. Using both keeps the transducer from spinning and the fairing aligned. Plan the mounting location around clean water flow and cable routing before drilling or bonding anything in place. Browse more fish finder accessories.
