Seasonal storage of water equipment requires a special approach, especially when it comes to powertrain. Bracket for storage of the outboard motor It is not just a convenience, but a critical component to prevent the deformation of the lower unit and moisture from entering the exhaust system. Incorrect positioning of the engine in the off-season can lead to expensive repairs that will cost more than the cost of the fastener itself.
Boat owners often underestimate the importance of fixing the motor in a vertical or strictly horizontal position. The suspension of a heavy unit on the wall or a special rack in the garage saves space and provides air access to all components. In this article, we will discuss in detail how to choose or manufacture a reliable storage system that will last for many years.
The Importance of Correct Engine Fixing
The main threat to the engine during the downtime is residual moisture and load on the structural elements. lower unit It can be lowered, and water can accumulate in the lower part, which, when frozen, can break the metal walls. bracketIt ensures complete discharge of the liquid from the cooling system.
In addition, long-term storage on the transom of the boat without additional insurance creates a constant load on the fasteners and the transom itself. This is especially true for PVC inflatable boats, where the pressure in the cylinders can vary depending on the temperature in the room. holder This is done by extending the life of both elements.
⚠️ Warning: Never keep a two-stroke motor in the upside down position without first draining the oil from the gearbox, this will cause the lubricant to be released through the glands.
Competent organization of space in the garage or in the country begins with an assessment of the weight of the unit. For light models up to 20 kg, a simple wall shelf will suit, while for heavy four-strokes weighing more than 50 kg, a reinforced structure with additional stiffness ribs will be required. Metal frame It must be able to withstand weight with a margin of at least 30%.
Types of designs for suspension of motors
The water accessories market offers a variety of solutions, from simple hooks to complex mechanical elevators, depending on the availability of space and the frequency of use of the boat.
- 🔹 Wall brackets Compact L-shaped or U-shaped structures attached directly to the wall are ideal for garages.
- 🔹 Floor racks - mobile designs on wheels, allowing you to move the motor around the workshop without removing the holder.
- 🔹 Ceiling elevators - systems of blocks and cables for lifting the engine under the ceiling, saving the most usable area.
Wall options require a capital wall of brick or concrete. bracket It is strictly forbidden to use drywall or foam block without embedded parts. There are special spacer anchors for such walls, but their load-bearing capacity is always lower than that of chemical anchoring in hard stone.
Floor racks are often equipped with a rotary mechanism, which makes it easier to maintain the engine. unit around its axis, accessing candles, filters or pumps without having to remove them. That at home.
Materials and strength requirements
The main material for the manufacture of load-bearing elements is a profile steel pipe or corner. The use of aluminum is only possible for very light motors, since this metal is prone to fatigue deformations under prolonged static load. Metal thickness It must be at least 2-3 mm to ensure that there is no deflection.
The most important aspect is corrosion protection. Garages are often damp, and the remaining salt water on the motor can drain onto the fasteners. So all the elements of the structure must be powder-painted or galvanized. Regular enamel will quickly peel off, and so the design will be completely stained with powder paint. rust It will begin to corrode the metal, weakening the structure.
For fastening to the wall, high-strength bolts with a diameter of at least 10-12 mm are used. The threaded joints must be tightened using growers or a thread fixer so that vibration (if the motor is stored on the network for charging the battery) does not weaken the fastener.
| Motor type | Weight (approximate) | Recommended profile | Fastening |
|---|---|---|---|
| 2-5 hp | 15 kg | Corner 40x40x4 | Anker 8 mm |
| 9.9 hp | 25-30 kg | Profile 40x20x2 | anchor 10 mm |
| 15-20 hp. | 40-50 kg | Profile 60x40x3 | anchor 12 mm |
| 30+bhp | 70+ kg | A 60x60 smack-tube | Chemical anchor 14 mm |
When welding the bracket, clean the seams and cover them with a primer before painting - this is where corrosion begins in the first place.
Instructions for manufacturing DIY
Creating a reliable holder yourself is a task that is available to any welder owner. The process begins with designing and measuring the dimensions of your particular welder. motorIt's important to consider not only the weight, but also the geometry of lower unit, so that the fulcrum does not press on the plastic casings.
To work, you will need the following tools and materials:
- 🛠️ Bulgarian and welding inverter.
- 🛠️ Roulette, coal mine and metal marker.
- 🛠️ Profile pipe 40x40 mm and 40x20 mm.
- 🛠️ Paint on rust and brush.
First, you cut the main frame in the shape of the letter "G" or "P." The vertical part is attached to the wall, the horizontal takes weight. At the ends of the horizontal shelves, you need to weld small sides or plugs so that the motor does not slip off in an accidental push. Welded seams They should be solid, without burns.
⚠️ Warning: Before the final installation, check the design for deflection, hanging a load exceeding the weight of the engine by 10-15 kg.
Once assembled, the frame is degreased and painted, the paint must dry for at least 24 hours, only after drying completely can the wall be mounted, holes are drilled, the anchor is inserted and the nuts tightened tightly.
☑️ Pre-installing check
Features of storage of different types of engines
Two-stroke and four-stroke engines have different storage positioning requirements; two-stroke engines are more sensitive to the position of the carburetor and fuel system; and for long-term storage, it is recommended to close the fuel faucet and produce residues of gasoline, which is easier when the engine is on the ground. bracket in the working position.
Four-stroke engines have a lubrication system in the crankcase. It is important that oil does not flow into the cylinder through the piston rings, although modern oil seals hold well. However, you can not store the four-stroke upside down categorically - oil will get into the valve mechanism and hydraulic shock can occur when starting.
Do I need to remove candles during storage?
Yes, it is recommended to twist the candles and pour 5-10 ml of engine oil into the cylinders, then slowly turn the starter several times (with open ignition contacts), this will create a protective film on the cylinder walls.
Electric motors require contact protection from oxidation. bracket In a dry room, the ideal solution is to not leave the battery connected to the engine for the whole winter, it is better to store the battery separately on a shelf with regular recharging.
Caring for the storage system and motor
Even the strongest bracket requires periodic inspection. Every six months, check the tightening of anchors and no corrosion on welds. If you keep the motor outside under the canopy, metal elements can rust faster, so you should wipe them with anticoric rags.
The engine itself must be preserved before it is installed for storage. Rinse the cooling system, replace the oil (for 4T), treat the external surfaces. spray-preservativeA clean and dry engine on a reliable bracket ensures that you start it the first time in the spring.
Remember to dust off the horizontal surfaces of the holder. The dust that has been accumulated, combined with humidity, forms an abrasive mixture that can scratch the paintwork of the lower unit when installing and removing the motor.
Frequently Asked Questions (FAQ)
Can I attach the bracket to a brick wall with old plaster?
You can fix it, but only if the anchor goes through the plaster and goes deep into the brick or concrete, and if the plaster is removed carefully at the drilling site, the anchor will hold onto the load-bearing material, and if the plaster crumbles, it needs to be replaced with a repair compound.
How high is the bracket shelf to make?
The optimal height of the horizontal shelf is at the level of your chest or slightly higher (about 140-150 cm from the floor), which will allow you to easily remove and put the engine without leaning too low and without getting on tiptoes.
Do I need to cover the engine with a cover on the bracket?
In a dry heated garage, a case is not required, it is enough to keep the engine clean. In an unheated room or on the street, a case is necessary to protect against dust, condensation and ultraviolet light that destroys plastic parts.
Will the bracket withstand a full tank of gasoline?
The bracket should always be calculated with a margin. A full tank adds 5-10 kg of weight. If the structure is designed for 50 kg, it will withstand a full tank, but it is better to always drain the fuel before long storage for fire safety reasons.
A properly designed and installed bracket is an investment in the durability of your outboard motor and the safety of your garage.
