Technical Specifications
Installation & Compatibility
Easy Transom Installation
The plastic transom mount design simplifies installation with standard marine mounting hardware included. The sensor mounts flush with the transom for optimal water flow and minimal turbulence. Pre-drilled mounting holes and template ensure precise placement for maximum performance.
Universal Compatibility
NMEA0183 digital output ensures compatibility with Furuno chartplotters, fishfinders, and navigation systems, as well as equipment from other leading marine electronics manufacturers. The 7-pin connector provides secure, waterproof connections in demanding marine environments.
Optimal Placement Guidelines
- Mount on flat transom surface away from propeller wash and turbulence
- Ensure sensor face is parallel to waterline when boat is at rest
- Maintain minimum 12-inch clearance from other through-hull fittings
- Route cable through existing wire runs or use marine-grade cable glands
Marine Applications & Benefits
Navigation Safety
Accurate depth readings prevent grounding and enable confident navigation in unfamiliar waters, while speed data helps with fuel economy and arrival time calculations.
Sport Fishing Enhancement
Water temperature data identifies thermoclines and temperature breaks where fish congregate, significantly improving fishing success rates and targeting efficiency.
Performance Monitoring
Real-time speed measurements help optimize boat performance, monitor fuel consumption, and verify GPS accuracy in areas with poor satellite coverage.

Frequently Asked Questions
What marine electronics systems are compatible with the 235DST-PWE?
The NMEA0183 digital output ensures compatibility with virtually all modern marine chartplotters, fishfinders, and navigation systems from Furuno, Garmin, Raymarine, Simrad, and other major manufacturers that support NMEA0183 data input.
How accurate are the depth and speed measurements?
The 235 kHz frequency provides excellent depth resolution and accuracy. Speed measurements are calculated from water flow over the sensor paddle wheel. Temperature accuracy is ±1°F (±0.5°C), meeting professional marine standards for environmental monitoring.
Can this sensor be used in both fresh and salt water?
Yes, the 235DST-PWE is designed for both fresh and salt water applications. The plastic housing and marine-grade components resist corrosion in salt water environments while maintaining accuracy in fresh water conditions.
What is the maximum depth range for this sensor?
The 235 kHz frequency and 200-watt power output provide reliable depth readings from shallow waters to several hundred feet, making it suitable for coastal cruising, inland lakes, and offshore fishing applications.
Does the sensor require special maintenance?
Minimal maintenance is required. Periodically clean the sensor face and paddle wheel of marine growth and debris. Inspect connections annually and ensure the mounting hardware remains secure. The plastic construction resists corrosion and fouling.
Is professional installation recommended?
While the transom mount design allows for DIY installation, professional installation by a certified marine electronics technician is recommended to ensure proper placement, waterproof connections, and optimal performance. This also maintains warranty coverage.
