    Maretron M33-100 Bronze Housing Kit replaces the standard plastic through hull housing for the DST100 Smart™ Retractable Depth / Speed / Temperature Transducer

    * Notes:

    • Bronze housing recommended for fiberglass or wood hulls
    • Never mount a bronze housing in an aluminum hull because electrolytic corrosion will occur
    • Never install a metal housing in a vessel with a positive ground system

    Maretron offers two optional through hull housings in bronze and in stainless steel. The Maretron part number for the bronze housing is M33-100 and the Maretron part number for the stainless steel housing is M33-495-01 The plastic and bronze housings use the same size hole in the hull (2 inches or 51mm) where the stainless steel housing requires a 2.25" or 57mm hole through the hull.

    The DST100’s optional bronze, or stainless steel housing choices are compatible with any hull material. It includes a blank plug to replace its sensor unit when the vessel will be docked for extended periods or trailered. This prevents damage to the sensor and reduces fouling growth.
