How to Winterize an Electric Kayak: FluxJet Storage Guide

Winterizing your FluxJet starts with removing water, preparing the jet drive, taking out the battery and choosing supports that distribute the kayak's weight. A cover helps keep the kayak clean, but it does not replace those steps.

If your kayak will spend winter in a covered, unheated shed, look at the whole storage setup. Is the hull completely dry? Can rain enter through the roof or door? Are the supports appropriate? Will the battery experience temperatures outside its manufacturer's limits? Those questions matter more than whether the shed has a heater.

The FluxJet support page contains the Owner's Manual and a drive-lubrication video. Use those resources for the exact procedure on your kayak. This guide explains how to organize the work before an extended break.

What Winterizing a FluxJet Actually Involves

The list is short: get the water out, inspect and lubricate the drive, take the battery out, and support the hull properly. That is the whole job. The sections below walk through each one in order.

One caution before you start. Do not borrow steps from an outboard winterization checklist. The FluxJet manual does not call for antifreeze in the jet drive, and there is no fuel system or engine oil to deal with. If you cannot confirm that water has drained from an area, ask FluxJet before adding any chemical or taking components apart.

And this is not only about winter. Run the same routine before any extended pause, even one caused by travel. The drive's pre-storage lubrication requirement kicks in before a break of more than ten days.

Step 1: Clean Before Putting the Cover On

Choose a stable place to work and disconnect power before inspecting or cleaning around the intake. Remove the battery box and wipe it down. Close both access hatches, the front cover, and the connections before rinsing the outside so you do not intentionally introduce water into the hull. Those hatches are wiring access covers, not storage compartments. Nothing is stored inside them, and they stay shut while you rinse.

Use fresh water and low pressure. Remove visible mud, grass, sand and fishing line from accessible areas. Pay attention to the intake area, steering bucket, pedals and steering lines. Do not aim a pressure washer into the drive, electronics or deck padding.

Saltwater owners should also flush the drive the way the manual describes: run the motor on low power with a hose on low pressure into the rear of the jet pump for one to two minutes. A quick wipe of the deck does not address salt remaining around the drive and steering components.

Step 2: Drain, Then Allow the Interior to Dry

After rinsing, pull the hull plug and tip the kayak so any water inside the hull runs out. A little water inside is not unusual; it can get in through condensation or past a hatch seal over time, and the plug is there so you can drain it. Then open the access hatches and wipe the accessible interior areas with a cloth dampened with fresh water, taking care around the wiring.

Leave the hatches open and let the kayak dry in a sheltered area away from direct sunlight until the interior is fully dry. That is the only reason to open them outside of service work, and the manual requires a fully dry interior before long-term storage. A hull that looks dry on top can still hold water inside.

Do not close up a wet kayak because the forecast has turned cold. Give drying its own time in the storage plan, particularly after the last saltwater trip. If a lot of water repeatedly appears inside, check the hatch covers and seals rather than assuming winter storage will solve it.

Step 3: Prepare the Drive for the Break

Check the intake for an obstruction and look for damage that deserves attention before next season. Keep power disconnected during inspection. Do not reach through the grate or force a component to turn.

The manual's bearing-lubrication schedule includes service before storage longer than ten days. It also specifies a minimum interval of thirty freshwater trips or twenty saltwater trips. The coupler threads in through the steering bucket to the grease fitting on the drive housing, and the manual specifies a long-reach coupler (the LockNLube XL) with marine-grade grease. The limit is two slow pumps. More grease is not better here: over-greasing can build enough pressure to dislodge the grease cap and damage the drive.

Watch the manufacturer's lubrication demonstration through FluxJet support. If the coupler does not seat correctly or you are unsure about an existing problem, ask for help before proceeding.

Step 4: Remove and Store the Battery Separately

Turn the battery-box breaker off, disconnect the system and remove the battery. Check the case and terminals and make sure the box is dry.

The correct storage charge and temperature depend on your exact battery. Do not assume that a recommendation for one lithium brand applies to another. Write down the model, recommended charge level, permitted storage range and next check date before putting it away.

An unheated shed is not automatically suitable for the battery just because it is suitable for the kayak. Cold storage and cold charging have different limits. Consult the battery maker before charging a pack that has spent the night in freezing conditions. Our FluxJet battery selection guide explains the kayak's battery options.

Step 5: Support the Hull and Protect the Storage Space

For extended storage, the manual favors carpet-wrapped bunks about eight feet long, spaced sixteen inches center to center. It does not recommend sawhorses. The aim is to distribute the load rather than concentrate it at two small contact areas.

Loosen transport straps once the kayak is safely stored. Remove unnecessary heavy gear. Make sure the rack or trailer is stable and that the drive and steering components are not carrying the kayak's weight.

Inspect the shed for roof leaks, flood exposure and signs of animals. A ventilated cover is a practical way to reduce dust without deliberately sealing residual moisture inside. Recheck the setup after severe weather and address a displaced cover or wet floor promptly.

Built Underneath, Built to Be Serviced

The FluxJet drive sits underneath the hull, inside the boat, with no propeller hanging below it. That is what you are inspecting in Step 3: one intake grate and an enclosed impeller. No bent prop, no fishing line wrapped around a shaft, nothing exposed to whack against the trailer bunks.

It is also built to be serviced by the owner, not sealed shut. The lubrication point takes a standard long-reach coupler, the schedule is printed in the manual, and the entire pre-storage service is the two-pump job in Step 3. If you find wear, parts are available and the support team is a phone call away. See jet drive versus trolling motor for how the two systems compare.

Winter Storage FAQs

Can I keep my FluxJet in a shed without heat?

A sheltered, dry shed can be a practical storage location if the hull is properly supported and protected from weather. The manual does not give a universal shed-temperature approval. For extreme temperatures or an unusual rack arrangement, ask FluxJet. Evaluate the removed battery separately against its manufacturer's limits.

Is a cover enough to winterize the kayak?

No. Clean and dry the kayak, inspect and lubricate the drive as required, remove the battery and support the hull correctly before covering it.

Should I leave the battery connected all winter?

No. FluxJet calls for battery removal during storage, including its short-term storage guidance. Follow your battery maker's instructions after removal.

Do I need antifreeze in the jet drive?

The manual does not provide an antifreeze winterization procedure. Follow its draining and storage instructions and ask support about any water you cannot remove.

Can I store it on sawhorses?

The manual advises against sawhorses for storage. Use the recommended distributed support configuration.

What should I check before using it again?

Inspect the hull, seals, wiring, intake, steering and battery. Put the hull plug back in and perform the pre-use checks before launch. Plan a short first outing.

Put It Away Ready for the Next Season

A good storage routine leaves you with a clean, dry kayak and a record of completed maintenance. If you found wear, leakage or an electrical issue, contact FluxJet before the next trip rather than leaving the problem for launch day.
