Quick answer: storing an outboard off the boat
Store an outboard upright (vertical), on a stable stand or bracket rated for its weight, after fogging the cylinders, stabilising or draining fuel, and letting the gearcase drain. Upright storage lets cooling water drain out so nothing is left to freeze or sit in the leg, and a proper stand keeps the motor stable and accessible instead of leaned in a corner.
Storing a motor on its side or at an angle can trap water and let oil migrate where it should not, so upright is the standard for anything beyond very small portables (which have their own maker guidance). The main winter risks are frozen or corroded internals, fuel going stale, and physical damage from a motor that is unstable or resting on its skeg.
This guide covers preparation and the stand. For stand types and uses, see outboard motor stand types and uses; for the gearcase/lower unit specifically, see the lower unit stand guide.
Guide
Preparing the motor before storage
Most of the value in off-boat storage comes from preparing the motor properly before it goes on the stand.
Follow the engine manufacturer's winterizing procedure, which typically includes flushing with fresh water, fogging the cylinders to coat internals against corrosion, treating or draining fuel so it does not go stale and gum the system, and changing or checking the gearcase oil (which also reveals water intrusion). Let cooling passages drain fully so no water is left to freeze. Disconnect and store the battery separately where relevant.
These steps are about corrosion and fuel, and they are best done before the motor is set for storage. Use the maker's specified products and intervals rather than generic advice, and do not improvise chemical mixes. With preparation done, the motor is ready to be stored upright and stable.

Storing the motor upright on a stand
Once prepared, the motor needs to be stored upright and stable — which is what a dedicated outboard motor stand provides.
An outboard stand holds the motor vertically at a convenient height, clamped at the transom bracket as it would mount on a boat, so cooling water drains and the gearcase sits correctly. Compared with leaning the motor against a wall or resting it on its skeg, a stand keeps it from tipping, protects the leg and propeller, and gives all-round access for service. For a yard storing several motors, stands keep them organized and off the floor.
The stand must be rated for the motor's weight and stable on the floor — a heavy outboard on an undersized or wobbly stand is a hazard. KIPAC manufactures CE-documented outboard motor stands built for this, with the capacity stated and traceable. Choose the stand to suit your motor's weight and how you will use it; see the outboard motor stand buying guide.

Where and how to keep it through the season
Where the motor lives over winter matters almost as much as how it is prepared.
Keep it in a dry, ventilated space, off a cold damp floor, and out of the way of knocks. Cover it loosely with something breathable so debris stays off without trapping condensation against the powerhead. Keep the propeller and leg protected, and label fuel and battery so reconnection is straightforward in spring. If the motor is stored in a shared yard or store, a stand keeps it clearly its own unit rather than balanced precariously among others.
Through the season, a quick check confirms nothing has shifted and no damp is collecting. Come spring, a motor that was drained, fogged and stored upright on a stable stand is far quicker to recommission than one left leaning and unprepared. The general boat-side routine is covered in the wider winterizing guides; this article focuses on the motor off the boat.

Common mistakes storing an outboard
A few mistakes account for most off-season outboard damage.
The first is storing the motor on its side or at an angle, trapping water and letting oil migrate — upright is the rule for all but the smallest portables, per the maker. The second is skipping fogging and fuel treatment, so internals corrode and fuel gums over the winter. The third is leaving cooling water in the leg to freeze and crack components. The fourth is resting the motor on its skeg or leaning it against a wall, risking a fall and damaging the leg or propeller.
The fifth is using an undersized or unstable stand that cannot safely hold the motor's weight. A motor is heavy and concentrated, so the stand must be rated for it and stable on the floor. KIPAC manufactures CE-documented outboard motor stands with traceable capacity for exactly this; choose by the motor's weight and intended use, confirmed at quotation.
Checklist
Outboard off-boat storage checklist
Flush with fresh water and let cooling passages drain fully so nothing is left to freeze in the leg.
Fog the internals per the engine maker's procedure to protect against corrosion over winter.
Stabilise or drain fuel so it does not go stale and gum the fuel system.
Check or change gearcase oil per the maker; cloudy oil signals water intrusion to address before storage.
Mount the motor vertically on an outboard stand rated for its weight, clamped at the transom bracket.
Store in a dry, ventilated space, off the floor, loosely covered with a breathable cover, leg and prop protected.
Label fuel and battery, and check through the season that nothing has shifted or collected damp.

FAQ
Upright (vertical) is the standard for all but the smallest portable motors, because it lets cooling water drain out of the leg and keeps oil where it belongs. Storing a motor on its side or at an angle can trap water and let oil migrate. A dedicated outboard stand holds the motor vertically and stable. Very small portables have their own manufacturer storage guidance to follow.
Prepare it first — flush, fog the cylinders, treat or drain fuel, check the gearcase oil and let cooling passages drain — then mount it upright on an outboard motor stand rated for its weight, clamped at the transom bracket. Keep it in a dry, ventilated space off the floor, loosely covered, with the leg and propeller protected. Follow the engine maker's specific winterizing steps and products.
A stand holds the motor upright and stable so cooling water drains and the gearcase sits correctly, protects the leg and propeller from a fall, and gives all-round access for service. Leaning a motor against a wall or resting it on its skeg risks tipping and damage. For a yard, stands also keep multiple motors organized and off the floor.
The stand must be rated comfortably above the motor's weight and stable on the floor, since outboards are heavy and concentrated. Choose by your motor's weight and how you will use the stand (storage, service or moving it). KIPAC manufactures CE-documented outboard motor stands with stated, traceable capacity; the right model is confirmed against the motor during quotation.
Yes. KIPAC manufactures CE-documented outboard motor stands that hold a motor upright and stable off the boat for storage, service and handling, with the load capacity stated and traceable. The suitable stand depends on the motor's weight and intended use, confirmed with the KIPAC team during quotation.
