Professional Installation Advantages

The P19 design represents the optimal balance between performance and hull integrity. The ultra-low-profile configuration minimizes water flow disruption, making it ideal for high-performance vessels where speed and fuel efficiency are priorities. The nearly flush-mount design also reduces the risk of impact damage in shallow water or during hauling operations.

Installation Specifications: Requires a clean 2-inch diameter hole through the hull with appropriate marine sealant and backing plate. The built-in deadrise compensation eliminates the need for angled installation in most applications, simplifying the installation process while maintaining accuracy.

Marine Environment Performance

The Lexan plastic construction provides excellent durability and chemical resistance against marine growth, salt corrosion, and UV exposure. Unlike bronze through-hulls, the plastic construction eliminates galvanic corrosion concerns and provides consistent performance in all water conditions. The smooth surface finish resists marine growth accumulation that can affect transducer performance.

Navigation & Fishing Applications

The 200 kHz frequency provides excellent detail resolution for both navigation safety and fishing applications. Higher frequency operation delivers superior bottom detail and fish separation compared to lower frequency transducers, making it ideal for coastal cruising, sport fishing, and shallow water navigation where precise depth measurement is critical.

System Integration Benefits

Seamless integration with Raymarine’s SeaTalk network enables depth data sharing throughout the vessel’s instrumentation system. Multiple displays can simultaneously show depth information, while the data can be integrated with chartplotters, autopilots, and other navigation systems for comprehensive situational awareness.

Frequently Asked Questions

Which Raymarine instruments are compatible with the M78713-PZ?

The M78713-PZ is directly compatible with ST60+, ST290, and i50 instruments. It’s also compatible with ST70 (requires ST70 Depth Pod) and i70 (requires ITC-5 converter) with additional components.

What hull materials are compatible with this plastic transducer?

The P19 plastic transducer is compatible with aluminum, metal, and fiberglass hulls. The plastic construction eliminates galvanic corrosion concerns common with bronze transducers on aluminum hulls.

How much does this transducer protrude below the hull?

The ultra-low-profile design extends only 5mm (3/16 inch) below the hull surface, making it nearly flush-mounted. This minimal protrusion virtually eliminates drag and reduces the risk of impact damage.

What deadrise angles can this transducer accommodate?

The M78713-PZ accommodates deadrise angles from 0° to 8° through built-in deadrise compensation. The ceramic element is tilted inside the housing to provide accurate readings without angled installation requirements.

Does this depth transducer include temperature or speed sensing?

No, the M78713-PZ is a depth-only transducer operating at 200 kHz. It does not include temperature or speed sensing capabilities, focusing exclusively on precise depth measurement for navigation and fishing applications. Lexan Depth Transducer f/ST60 & ST290
