Keep your gear running smoothly with Silicone Dielectric Grease / Compound, designed to prevent corrosion and maintain clean, functional connections. Ideal for your boat's navlight port pins, this compound ensures uninterrupted power for your GoPro, DJI, Tactacam, or any USB-powered device. Just like your car battery, if you don’t protect your ports from moisture, corrosion can build up and damage your equipment. Use it on all electrical connections on your boat—fish finders, batteries, and more. Before inserting your PowerStick-53" or PowerStick-20" into your navlight port, check for cleanliness and corrosion, as dirty or corroded ports can damage your gear. Simply clean the port and pins, coat them with the compound, and slide your YOLOtek gear in with ease. For freshwater use, apply the compound after each trip; for saltwater use, clean the port after every outing and apply the compound to keep everything running flawlessly.
