Matt Nuzzo: Hard lessons learned for maintaining your Foil Drive.
What’s up everybody? Matt Nuzzo here at REAL in the rental shop, and today we’re talking about Foil Drive maintenance. I’ve definitely messed this up before, so I want to walk you through exactly what you need, how it works, and what you should be doing.
First, here’s what you’ll need: dielectric grease (the battery grease that comes with your Foil Drive), Teflon grease, standard marine grease from a hardware or marine store, and a lanolin spray like Fluid Film.
Let’s start with what you should do after every session. Rinse the entire unit with fresh water. If you’re riding in fresh water you can skip this, but otherwise it’s critical to prevent corrosion. Make sure the battery case is closed before rinsing. Remove the rotor hub and rinse out the stator and surrounding areas since sand can build up there. Leave the rotor off so the stator can fully air dry. Rinse your controller as well and actuate the trigger to flush out salt, then let everything dry.
Every three sessions, use lanolin spray as a rust inhibitor. Spray inside the hub and around the stator to keep it protected and lightly lubricated. The goal is to prevent corrosion and buildup.
Every ten sessions, apply a small amount of marine grease to the stator bearing and spindle—just a thin layer, not packed. Then add a small dab of dielectric grease to the battery terminals to maintain a clean connection and prevent corrosion.
Every twenty sessions, you’ll want to fully disassemble the unit. This is a critical step that’s easy to skip. Remove the motor cable, mast, and mounting hardware. Once apart, you’ll likely find salt, sand, and moisture trapped underneath—especially under the mast pad and foam tracks where water can sit and cause corrosion.
Clean everything thoroughly using a towel, removing buildup, sand, and old grease. Let all components fully air dry. Apply lanolin spray to protect against future corrosion. Open the battery cover and let the entire unit dry overnight before reassembly.
When putting everything back together, keep the battery cover on to prevent debris from entering. Work in a clean area. Use a small amount of Teflon grease on metal-to-metal contact points like bolts and motor cable connections. Apply dielectric grease to the battery O-ring seal.
For long-term or winter storage, store the battery at around 50% charge—never fully empty or fully charged. Keep it in its case and add a bit of grease to the terminals. Make sure the controller is clean, dry, and partially charged. Fully disassemble the unit, clean it, and store all parts separately to prevent corrosion.
Follow these steps and your Foil Drive will last a long time. These units have proven to be extremely reliable, and proper maintenance ensures you’ll get the most sessions possible. If you have any questions, give us a call or reach out online. See you on the water.
