Excessive board flex can momentarily reduce sealing pressure around the nose cone during pumping or hard landings, allowing small amounts of water to enter.If this occurs, inspect your setup and ensure all sealing surfaces are clean and correctly assembled.<h1 id="isPasted" style="text-align: center; line-height: 2;">Using Dielectric Grease</h1>Applying dielectric grease correctly is one of the best ways to protect your system.The grease protects:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Battery terminals</li><li style="font-size: 14px; line-height: 2;">Motor connectors</li><li style="font-size: 14px; line-height: 2;">Internal power contacts if water enters the unit</li></ul>Only use Foil Drive dielectric grease.&#xA0;Other products may affect electrical performance or connector reliability.<h2 id="isPasted" style="line-height: 2;">How Much Grease Should I Use?</h2>You do not need excessive amounts.Apply:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">A light coating around the circumference of the plug on your battery and motor cables</li><li style="font-size: 14px; line-height: 2;">A light coating on the O-ring</li></ul>Avoid applying grease across the terminals, as excessive grease can affect electrical contact.
