NASA Speed Speed Speed Skin Fitting for Speed Log Sensors | 4Boats

A skin fitting provides a watertight through‑hull mount for hull‑mounted speed log transducers, positioning the sensor in the water while protecting the hull and allowing service without full dry‑docking.

• Material: marine bronze alloy, corrosion‑resistant
• Application: hull‑mounted speed log / transducer installation
• Mounting: through‑hull flange with O‑ring/seal and internal securing
• Hull thickness compatibility: suits up to 25 mm (1 in)
• Installation: requires precision cut‑out and marine sealant; bolt pattern for secure fit
• Service: removable from inside the hull for maintenance without dry‑docking
• Compatibility: accepts most industry‑standard speed log transducer stems—check sensor thread/diameter

Suitable for recreational and commercial vessels; have the fitting installed or checked by a qualified marine engineer to ensure correct alignment and watertight sealing.
