Maretron Non-Displacement Hull Focus Tube SAE 5-Bolt

The Maretron Non-Displacement Hull Focus Tube SAE 5-Bolt is an essential through-hull transducer mounting system designed for anglers and boaters who require precise sonar performance while maintaining hull integrity. This 43-inch focus tube is specifically built for marine electronics integration, accommodating standard SAE 5-bolt fastening patterns used in Maretron and compatible marine navigation systems.

The non-displacement hull tube allows for transducer mounting without the need for material removal or additional weight, which is a significant advantage over traditional through-hull installations. It is designed to ensure secure, vibration-resistant fastening that minimizes signal loss due to mechanical movement. This focus tube's compact dimensions of 3x3 inches make it easy to integrate into various boat layouts, protecting the transducer element from damage and fouling.

Ideal for cruisers, fishing boats, and center consoles utilizing Maretron chartplotter and sonar systems, this mounting tube is particularly beneficial for mid-ship or stern transducer placements. Proper installation with SAE-compatible fasteners and appropriate marine-grade sealant is crucial for ensuring a watertight fit, enhancing the overall performance of your marine electronics.
