ST300/P371 Plastic Low Profile Through Hull Speed Transducer. For use with ST40 Instruments. Speed and Temp only. 200 kHz.
ST300 Thru-hull Shorty™
The S300/ST300 speed sensors are our lowest cost and shortest thru-hull speed sensors. As part of our Shorty™ Series, they are designed for boats with low headroom. The plastic P371 low profile outer housing option is nearly flush and minimizes drag with only 5 mm (3/16") extending outside of the hull. The plastic P398 countersunk outer housing option mounts flush, eliminating turbulence for more accurate speed readings.
