Raymarine ST300, Thru-hull Shorty™

The Raymarine ST300 Thru-hull Shorty is a compact speed and temperature transducer designed for anglers and boaters who demand reliable water data without sacrificing deck space. This thru-hull sensor integrates directly into your hull to provide real-time speed and temperature readings, critical information for targeting fish patterns, optimizing fuel efficiency, and navigating safely across varying water conditions.

Built by Raymarine, a trusted name in marine electronics, the ST300 Shorty is engineered for vessels where traditional through-hull installations are impractical or where a streamlined profile is essential. Its reduced-length design minimizes hull intrusion while maintaining the electrical and mechanical performance expected from Raymarine's marine-grade construction. The sensor communicates with compatible chartplotters and navigation systems via standard marine networks, delivering accurate water temperature and vessel speed data that directly influences your fishing strategy and boat performance monitoring.

Anglers operating center consoles, bay boats, or vessels with limited transom real estate will find the ST300 Shorty an ideal retrofit or new-build option. Its compact footprint suits aluminum and fiberglass hulls alike, and it pairs seamlessly with Raymarine's full line of integrated systems, ensuring that you have the best tools at your disposal for successful outings on the water.
