ST300 Shorty™ Thru-hull
Part NumberST300
Speed and Temperature
The ST300, speed and temperature sensor is low in price and short in size. As part of our Shorty™ Series, it is designed for boats with limited headroom. The total height of housing is only 75 mm (2.96"). And the P371, low-profile housing is nearly flush and minimizes drag with only 5 mm (3/16") extending outside of the hull. The optional, P398, countersunk housing mounts flush, eliminating turbulence for more accurate speed readings.
