As the off-season arrives, every boater is faced with the question of proper storage of attachments. engine In a winter boat, you risk the integrity of the transom and the unit itself due to snow loads and temperature changes. boat-mountingIt frees up space and ensures the safety of the equipment.
Competent organization of storage space allows not only to protect expensive equipment from accidental damage, but also to facilitate access to it for preventive maintenance. bracket Or a homemade structure made of a profile pipe can withstand the weight of even a heavy four-stroke, if the installation technology is followed, in this article we will discuss all the nuances of creating a reliable fixation point.
There are many options, from simple wooden bars to complex swivel mechanisms with locks, the choice of the specific solution depends on the material of the supporting wall, the weight of your body. Yamaha or TohatsuAnd the budget you're willing to put in for the garage renovation, which is to make sure that the structure is rigid and that it doesn't have any vibrations.
Selection of the place and preparation of the load-bearing surface
The first step is always a thorough analysis of the load-bearing capacity of the wall. Brickwork Or monolithic concrete is ideal for heavy brackets that can hold weights of 50, 100 or more kilograms. concrete or foam block, you will need the use of special chemical anchors or through studs, as conventional dowels may not withstand the dynamic load when removing the engine.
It's important to consider the dimensions of the room. The motor should hang at such a height that the deadwell (leg) does not touch the floor, but you had the opportunity to comfortably conduct the car. conservation The optimal position is when the deadwell is at the level of the belt or slightly higher, which allows easy accessing drain holes and inspecting the deadwell.
⚠️ Attention.Never attach heavy motor brackets over 15 hp to hollow walls without first consulting a civil engineer. A heavy unit fall can cause serious injuries and damage to parts of the building structure.
Before starting work, you need to clean the surface of old plaster or paint in the drilling areas, which will ensure that the metal plate of the bracket fits tightly to the base. level for marking holes, as skewing even a few millimeters can create unnecessary stress in the metal of the fastener.
Types of wall fasteners for outboard motors
The water accessories market offers different solutions, but the three main types of designs remain the most popular, each with its own advantages depending on the frequency of use of the boat and the availability of free space in the room.
The first type is staticThey're a rigid metal frame welded onto a mounting plate, and the motor is put on them just like the snail of a boat, and it's the most reliable and cheap solution, and it eliminates movable parts that tend to rust or jam. turning-pointAllows you to move the motor away from the wall, saving space during the passage.
Comparison of the cost of ready-made solutions
Prepared brackets from well-known brands like Attwood Homemade analogues from the profile pipe are 3-4 times cheaper, requiring only the cost of metal and electrodes. At the same time, the functionality of homemade structures often exceeds store counterparts due to individual fit for a specific motor.
The third option is pillar They're convenient if you have multiple boats with different transom heights, or if you're planning to switch to a more powerful and larger engine in the future, and you're usually adjusting by rearranging your fingers or bolts in your profile holes.
- 🔩 Hard fixation: maximum reliability, minimum price, no moving parts.
- 🔄 The turning mechanism: saving space, easy access to the motor from all sides, more complex design.
- 📏 Adjustable height: versatility for different models, the possibility of changing the configuration, the presence of additional mounting points.
Manufacture of the bracket yourself: step-by-step instructions
Creating a reliable fastening yourself is a task quite solvable for a person who has basic skills in working with a welding machine and BulgarianTo work, you will need a profile tube of square cross-section (for example, 40x40 or 50x50 mm), a metal strip with a thickness of at least 4-5 mm to simulate a transom plate, as well as fasteners.
☑️ Checklist for assembling bracket
Start by welding the main frame. scarves The transom plate on which the motor will rest must be made of thick metal and have slots that repeat the standard distances between the motor fasteners. Usually this distance varies, so it is better to make elongated slots or a series of holes.
After assembly, welded seams must be cleaned and processed corrosion-proofThe best option would be to have a rust primer and then paint it with enamel in two layers, which would protect the structure from the moisture that would inevitably be present on the engine after operation.
⚠️ Attention.: When welding, make sure that the structure does not receive a "propeller". Check the plane of the bracket on a flat surface during cooking, as the skewed mount will create an uneven load on the hub of the motor.
Installation technology and selection of fasteners
The quality of installation depends on the right choice. anchor-boltFor brick and concrete walls, spacer anchors with a nut or hook are optimally suited. The diameter of the fastener should correspond to the weight of the engine: for light engines (up to 20 kg), an M8 anchor is enough, for medium ones (up to 50 kg) - M10, and for heavy four-strokes (50 + kg), it is recommended to use M12 or more.
The installation process begins by putting a bracket on the wall that is marked, and through the mounting holes, the drill points are marked with a pencil or marker, and then the punch drills holes that are 5-10 mm deeper than the anchor so that the dust does not interfere with the entry of the fastener, and after cleaning the hole, the bracket is re-applyed and fixed.
>The stains should be made evenly using dynamometer Or simply by following the cross-to-cross sequence to avoid skewing the plate. After the final tightening of the nuts, it is recommended to apply a drop of paint or varnish to the thread to prevent spontaneous unwinding from vibration.
| Motor weight (kg) | Type of wall | Recommended anchor | Min. diameter (mm) |
|---|---|---|---|
| 25 | Concrete/Brickpicch | Dissolute nut-and-nut | 8-10 |
| 25 - 60 | Concrete/Brickpicch | Chemical anchor/Highp | 10-12 |
| 20 | Full-bodied brick | The scoring anchor | 10 |
| Anyone. | Empty block | A through stud | 12-14 |
The main criterion for choosing a fastener is the bearing capacity of the base, not just the weight of the motor. In doubtful cases, always choose a fastener with a margin of safety.
Corrosion protection and storage safety
Water-motor equipment is in constant contact with aggressive environments, so its storage area must also be prepared. corrosionIt is recommended to inspect the condition of the paint on the bracket once a season and to paint the chips.
Storage security also includes protection against theft. The motor hanging on the wall is available, but that doesn't mean it's not protected. cables with locks, passing them through the regular holes in the deadwell or through fasteners, fixing them to a reliable element of the garage structure.
Keep it clean. You can drip residual fuel or oil under the hanging motor. You can put a pallet on the floor or use it. absorbentTo avoid the formation of a fire-hazardous puddle and damage to the floor covering.
- 🛡️ Anti-corrosion lubricantRegularly treat exposed metal parts of the WD-40 bracket or analogues.
- 🔒 Additional fixation: Use a chain with a lock to protect against theft in general garage cooperatives.
- 💧 Control of leakage: install a drip tray so that the oil does not spoil the floor and does not create a slippery surface.
Frequent errors in installation and operation
One of the most common mistakes is the use of plastic-dowel Plastics eventually dries up or floats under constant load, which can cause the engine to fall, and the need to align the bracket horizontally is often ignored, leading to uneven weight distribution.
Another mistake is to attach to the decorative wall covering, drywall, wafer or siding will not withstand the weight of even a small two-stroke. layer-bearing walls, bypassing the insulation and lining, using elongated hairpins if necessary.
If you store the motor on the bracket for a long time (all winter), remove the spark plugs from it and turn the crankshaft so that the lubricant is distributed to the cylinders, and put the bracket with wooden bars under the deadwell to relieve voltage from the transom plate of the engine.
And also, there's accessibility, and sometimes when you build a super-reliable structure, you forget to leave room for the side-mounted motor, and you have to take it off for transportation, you have to take out the half-bar. ergonomics beforehand.
⚠️ Attention.It is strictly forbidden to store the motor in an upright position on the bracket if there is fuel or oil left in the crankcase and the design does not involve draining liquids. This can lead to oiling of candles and the electrode of the soda.
FAQ: Frequently asked questions
Can I attach the motor to the wall of drywall?
The drywall itself will not support the weight of the engine, but if the walls were laid down, the engine would not be able to withstand the weight of the engine. mortgage From a bar or metal profile in the places of the proposed fastener, installation is possible, otherwise you will need to make a through mount through the wall to the supporting structure or build a separate counter-tournice.
How high is the bracket?
The optimal height is selected individually, but the standard is the location of the deadwell at a height of 120-140 cm from the floor. maintenance It doesn't require a high height to remove the motor from the wall.
Do I need to remove the motor from the bracket for the summer?
No, the bracket is for permanent storage, but in the summer, when you're in frequent use, many people prefer to keep the motor on a boat or on a special cart stand to be able to quickly go out into the water. long-term off-season storage.
Will the bracket withstand the engine with a dayvert?
Yes, the design is calculated under the full weight of the motor assembly, and it is important to make sure that the transom plate of the bracket is sufficiently wide and the appropriate holes for putting on. lower unit with clamping mechanisms.
