SmartSeal® Prevents Shaft Seal Damage or Failure from Over-Temperature Conditions

Published: Thursday, July 25, 2019

Gemeco is pleased to introduce a unique and innovative solution for early detection and prevention of shaft seal failures on recreational, commercial, and municipal vessels. New from Tides Marine, their SmartSeal® Temperature Sensors monitor the temperature of a boat's shaft seals and triggers a series of alarms when the water temperature exceeds the normal operating temperature range. “SmartSeal is an inexpensive and easy solution that works with any brand of shaft seal and operates as a standalone system or communicates over an NMEA2000® network, or both,” stated Peter Braffitt, General Manager of Gemeco Marine Accessories. “The sensor’s ability to communicate early warnings of potentially costly or life-threatening failures provide peace of mind to both family and crew,” Braffitt added.

SmartSeal solid-state temperature sensors detect an increase in water temperature within the shaft seal and will cause a warning alarm to sound, providing the crew with advanced notice of a problem. Further temperature increases trigger a critical alert indicating that a seal failure will occur if not corrected. Designed for quick connection to Tides Marine's SureSeal® products, this system also works with other manufacturers' dripless shaft seals by simply changing the existing NPT water injection fittings.

The control unit has a built-in engine room air temperature sensor and includes an output for an optional remote siren or for connection to an onboard warning/alarm system. Available for single or dual-engine installations, the SmartSeal kit includes a bulkhead mount control unit and sensor cable(s). Remote units designed for mounting at helm or flybridge positions as well as various NMEA components are also available.

SmartSeal main and remote units are IP66+ rated (waterproof for heavy spray and brief submersion) allowing units to be mounted in damp or wet locations. The panel mounted remote units are additionally O-ring sealed allowing use in locations that are exposed to rain or sea water (e.g. mounting on a flybridge). Installation guidelines and diagrams for NMEA and non-NMEA systems are available at
