Want to protect the threads and hardware on your Foil Drive electronics box? Learn the correct bolt installation, tightening and thread care practices to help prevent damage and keep your system secure and reliable.

Correctly installing and maintaining your motor bolts is important to prevent cross-threading, damaged threads and corrosion.If a motor plug bolt does not start smoothly or you feel resistance while tightening, stop immediately. Do not force the bolt, as this can damage the bolt or the threaded hole in your motor plug.For instructional video see:&#xA0;<a href="https://www.youtube.com/watch?v=Qvzuj_eArnA&amp;t=5s" target="_blank" rel="noopener noreferrer">Correct Motor Bolt Application, Care and Repair</a><h1 id="isPasted" style="line-height: 2; text-align: center;">Bolt Thread Maintenance</h1>Regular maintenance can help prevent corrosion and keep your motor bolts operating smoothly.<h3 style="line-height: 2;" id="remove-and-lubricate-the-bolts-regularly">Remove and lubricate the bolts regularly</h3>Remove the motor bolts regularly and apply a suitable lubricant to the threads.This helps reduce corrosion, particularly when the motor is regularly exposed to salt water.<h3 style="line-height: 2;" id="keep-the-threaded-holes-clean">Keep the threaded holes clean</h3>Sand and debris can become trapped inside the threaded holes and prevent the bolts from engaging correctly.To clean the threads:<ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Use a damp cotton bud/earbud.</li><li style="font-size: 14px; line-height: 2;">Carefully clean inside the threaded hole.</li><li style="font-size: 14px; line-height: 2;">Remove any sand, salt or other debris.</li><li style="font-size: 14px; line-height: 2;">Allow the area to dry before reinstalling the bolt.</li></ol>Tip: Regularly removing and cleaning the bolts is much easier than trying to repair damaged threads later.<h1 id="isPasted" style="line-height: 2; text-align: center;">Cleaning Up Damaged or Dirty Threads</h1>If your motor bolts are not going in smoothly or appear to be entering the threaded hole at an angle, the threads may need to be cleaned or repaired.Do not force the bolt into the hole.A suitable tool for cleaning up the threaded holes is an:<a href="https://www.bunnings.com.au/sutton-tools-m4-x-0-7-intermediate-hand-tap_p6370534?utm_source=chatgpt.com">Sutton Tools M4 x 0.7 Intermediate Hand Tap &#x2013; Bunnings Australia</a><h3 style="line-height: 2;" id="using-the-tap">Using the tap</h3>A Sutton Tools M4 x 0.7 Intermediate Hand Tap can be used to carefully clean and restore the existing M4 x 0.7 threads.If you are not confident using a tap or the threads are significantly damaged, we recommend contacting Foil Drive Support before attempting the repair.Important: The tap is intended to clean up the existing threads.

Electronics Box Bolt & Thread Care

Found water inside your Foil Drive nose cone? Learn what to check, what may be causing water ingress and the steps to take to safely inspect and protect your system.

If you can hear water inside your Foil Drive nose cone, don&apos;t panic.On some of the very early Foil Drive systems, water can enter and become trapped inside small cavities within the nose cone. These cavities are separate from the area where your battery and electronics are housed.For instructional video, see:&#xA0;<a href="https://www.youtube.com/watch?v=-QYDvenY8sE" target="_blank" rel="noopener noreferrer">Water in Gen2 Nose Cone</a><h3 style="line-height: 2;" id="is-the-water-damaging-my-system">Is the water damaging my system?</h3>No.The water is trapped inside the nose cone&apos;s internal cavities and does not enter the battery or electronics compartment.This means that, in these early nose cones, hearing water inside the nose cone is not an indication that your battery or electronics have been exposed to water.<h2 id="isPasted" style="line-height: 2; text-align: center;">Why Is There Water Inside the Nose Cone?</h2>The nose cone contains two small internal cavities, one on each side.On some of the earliest production units, the adhesive used to seal the small caps covering these cavities was not thick enough to completely prevent water ingress.As a result, water can enter through a very small gap and become trapped inside the cavity.This water may be audible when you move or shake the nose cone.The water is contained within these internal cavities and is separate from the sealed area that houses your battery and electronics.<h2 id="isPasted" style="line-height: 2; text-align: center;">Which Nose Cones Are Affected?</h2>This issue was limited to a small number of early production nose cones.Foil Drive subsequently identified the issue and updated the manufacturing process to improve the sealing of these cavities.Some early nose cones may:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Allow a small amount of water into the internal cavities.</li><li style="font-size: 14px; line-height: 2;">Have no visible signs of water ingress.</li><li style="font-size: 14px; line-height: 2;">Have already been modified or sealed as part of the updated manufacturing process.</li></ul><h2 id="isPasted" style="line-height: 2; text-align: center;">What Should I Do If I Can Hear Water?</h2>If your nose cone is one of the early versions and has water trapped inside it, there is no need to be concerned about damage to your Foil Drive system.The water is contained within the nose cone and does not affect:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Your battery</li><li style="font-size: 14px; line-height: 2;">The electronics</li><li style="font-size: 14px; line-height: 2;">The electrical connections</li><li style="font-size: 14px; line-height: 2;">The operation of your Foil Drive system</li></ul>The water is essentially a cosmetic nuisance rather than a functional issue.<h2 id="isPasted" style="line-height: 2; text-align: center;">Replacement Nose Cones</h2>Foil Drive has updated the manufacturing process to prevent water from entering these cavities.If you have an affected early nose cone and would like to replace it, complete the&#xA0;<a href="https://foildrive.com/pages/warranty" target="_blank" rel="noopener noreferrer">Warranty Claim Form</a>&#xA0;on the website.&#xA0;If you notice water inside your nose cone and are unsure whether it is simply trapped in the internal cavities or whether there may be an issue with the main electronics compartment, stop using the system and contact Foil Drive Support before attempting any repairs.

The left and right latches have different profiles and are not interchangeable.<h3 data-section-id="z276i0" data-start="3363" data-end="3412" id="isPasted" style="line-height: 2;">Can I use the spare bolts included in my kit?</h3>Yes. Every Foil Drive kit includes spare latch hardware, including replacement retaining bolts.<h3 data-section-id="w4a8y6" data-start="3525" data-end="3553" id="isPasted" style="line-height: 2;">Do I need to use grease?</h3>Yes. Applying dielectric or anti-corrosion grease to the retaining bolt threads helps prevent corrosion between the stainless-steel bolt and aluminium housing, making future maintenance much easier.<h3 data-section-id="1rbuf7p" data-start="3760" data-end="3806" id="isPasted" style="line-height: 2;">How do I know the lid is sealed correctly?</h3>After both latches are closed, there should be no visible gap between the nose cone, latches and the Electronics Box housing. The latches should close smoothly with even pressure.<p style="margin: 0px; color: rgb(31, 33, 36); font-family: -apple-system, BlinkMacSystemFont, &quot;San Francisco&quot;, &quot;Segoe UI&quot;, Roboto, &quot;Helvetica Neue&quot;, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: center; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; line-height: 2;">
