Overview / What Is Airmar 164WR-2 Wrench

The Airmar 164WR-2 wrench is a heavy-duty, precision-manufactured installation tool made specifically for Airmar’s through-hull B164 and B175 series transducers. Unlike generic tools, this wrench matches the transducer’s housing design, allowing for secure installation without damaging the threads, housing, or o-rings.

• Peace of Mind: Prevents accidental over-tightening or cross-threading during installation.

This makes the Airmar 164WR-2 wrench an indispensable addition to any boater’s or marine tech’s toolkit.

How to Install a Transducer Using Airmar 164WR-2 Wrench

Proper use of the Airmar 164WR-2 wrench ensures a safe, watertight seal for your transducer. Here’s a step-by-step guide on how to do it:

1. Apply marine-grade sealant around the transducer flange and insertion area.
2. Carefully insert the B164 or B175 transducer through the hull opening.
3. Use the Airmar 164WR-2 wrench to secure the locking nut onto the threaded housing.

Detailed FAQ Section

How do I know if I need the Airmar 164WR-2 wrench?

If you’re installing or replacing a B164 or B175 series transducer, the Airmar 164WR-2 wrench is highly recommended. These transducers are through-hull designs, requiring precise torque and alignment for a watertight seal. This wrench is manufactured specifically to match the size and threading of those models, unlike generic wrenches which may damage your equipment. If you’re unsure of your model, check the part number on your current transducer or consult the installation manual.

Can I use the Airmar 164WR-2 wrench on other transducer models?

The Airmar 164WR-2 wrench is engineered specifically for B164 and B175 transducers. While it may appear similar to other tools, using it on incompatible models can result in poor fitment and potential damage. For other transducer models, Airmar produces different specialized wrenches. Always consult Airmar’s compatibility chart or your marine electronics supplier to ensure you’re using the right wrench for your installation needs.

What is the durability of the Airmar 164WR-2 wrench?

Constructed from marine-grade stainless steel or composite materials (depending on production batch), the Airmar 164WR-2 wrench is built to last. With proper care, it can withstand harsh saltwater environments, repeated torque, and temperature variations without corrosion or warping. Users report multiple years of reliable service when stored properly and cleaned after exposure to marine elements. This makes it a long-term investment for both DIY and professional installers.

How much does the Airmar 164WR-2 wrench cost, and is it worth it?

The wrench typically retails between $39 and $55, depending on the supplier and whether you’re purchasing it bundled with a transducer. Given the cost of B164 or B175 transducers (often $600+), the Airmar 164WR-2 wrench is a modest investment that can prevent expensive mistakes. Its precision fit and durability make it highly cost-effective for any marine professional or boating enthusiast. Plus, using the code WELCOME5 at allboatsupplies.com offers an extra discount.

What are some best practices when using the Airmar 164WR-2 wrench?
