Common Concerns Answered
Does this sensor provide depth or temperature data?
The Raymarine ST300 Thru-hull Shorty™ is exclusively designed to provide boat speed data. For depth and temperature readings, separate compatible transducers and display units are required.
What if I need depth and temperature information too?
While the ST300 is a dedicated speed sensor, complementary Raymarine instruments or a multi-function display can integrate speed data with separate depth and temperature sensors to provide a comprehensive suite of information.
Is a display unit included with this sensor?
No, the Raymarine ST300 Thru-hull Shorty™ requires a compatible Raymarine instrument display or multi-function display unit to interpret and show the speed data it collects.
Frequently Asked Questions
What is the Raymarine ST300 Thru-hull Shorty™ designed for?
The Raymarine ST300 Thru-hull Shorty™ is specifically engineered for boats with limited headroom and applications where minimizing hull protrusion and hydrodynamic drag is a primary concern.
What are the advantages of the Shorty™ Series design?
The Shorty™ Series offers the lowest cost and shortest thru-hull speed sensors, ideal for installations where space is restricted and drag reduction is critical for optimal vessel performance.
What are the two outer housing options for the ST300?
The ST300 is available with a plastic P371 low profile outer housing, which offers nearly flush mounting and minimizes drag, or a plastic P398 countersunk outer housing for flush mounting and elimination of turbulence.
How much does the P371 low profile outer housing extend outside the hull?
The P371 low profile outer housing extends only 5 mm (3/16 inch) outside the hull, providing an ultra-low profile installation.
What is the benefit of the P398 countersunk outer housing?
The P398 countersunk outer housing mounts flush with the hull, effectively eliminating turbulence and ensuring accurate speed readings.
