• Extended Life - Proper maintenance extends instrument lifespan
• Cost Effectiveness - Kit replacement versus complete transducer replacement
• System Integration - Maintains accurate data for autopilot and navigation systems

Service Indicators

Replace your paddle wheel kit when you notice:

• Erratic Speed Readings - Inconsistent or jumping speed displays
• No Speed Reading - Complete loss of speed indication
• Calibration Drift - Speed readings consistently high or low
• Physical Damage - Visible wear, cracks, or missing paddle blades
• Water Intrusion - Moisture inside the transducer housing

Installation Considerations

Professional service recommended for optimal results:

• Proper Tools - Specialized tools may be required for transducer access
• Sealant Application - Proper O-ring installation prevents leaks
• Calibration - Speed calibration may be required after installation
• System Testing - Verify proper operation across all instrument displays
