ST300
The ST300, speed and is low in price and short in size. As part of our Shorty™ Series, it is designed for boats with limited headroom. The P371, low-profile, housing option is nearly flush and minimizes drag with only 5 mm (3/16") extending outside of the hull. The P398 countersunk housing mounts flush, eliminating turbulence for more accurate speed readings.
