Installation of an electric traction engine turns an ordinary inflatable boat into a full-fledged small-size vessel capable of covering long distances and effectively resisting wind and current. Electric motor attachment It's a critical node that not only makes fishing comfortable, but also makes you safe on the water, and unlike gasoline, electric motors are lighter in weight and vibration, but the rigidity requirements are high because of the specificity of the propeller.
Many owners PVC They're faced with a dilemma: use the standard inflatable transom that comes with the kit, or purchase a reinforced version. Inflatable elements often deform under the weight of the engine, which leads to a displacement of the lower unit and loss of driving efficiency. installation It requires taking into account the center of gravity, the weight of the battery and the specifications of the water transport itself.
In this article, we will take a look at all aspects of the installation, consider the necessary tools and materials, and discuss the nuances that are often silent in the instructions. Properly assembled design allows you to enjoy quiet running and maneuverability without fear for the integrity of the boat.
Selection of transone type for installation
The first step to successful operation is to choose the right site. transom board Standard inflatable transes, which are a cylinder with glued plywood, are only suitable for motors up to 1.5-2 hp or up to 30 pounds. stationary.
The stationary versions are made of moisture-resistant plywood, fiberglass reinforced or coated with special boat paint. They can be removable or pasted into cylinders. Removable transneum It is convenient for transportation and allows you to unload the boat during storage, but requires reliable mounts to cylinders.
⚠️ Attention: Never attach an electric motor weighing more than 10 kg to a thin inflatable transgress without additional rigid struts. This can cause the seams to rupture and the boat to sink quickly.
For electric motors, which often lack a tilt mechanism, the transom angle must be adjusted so that the lower unit enters the water perpendicular to the surface when the boat is in operation.
- 🔹 Inflatable trans-Trans: It is suitable for small capacity and calm water.
- 🔹 Removable plywood: A universal solution requires reliable slings.
- 🔹 Pluted transom: maximum stiffness, but complicates drying and packaging.
- 🔹 transom plate: A specialised solution for installing multiple motors or additional equipment.
Required tools and materials
Quality. motor-holding You need a toolkit that will ensure the accuracy and reliability of the connections, and you need to focus on the fasteners, because in water, constant vibration and humidity are the main enemies of all connections.
You'll need stainless bolts, nuts with grovers (spring washers) and washers of increased diameter, and you'll need to use conventional ferrous metal because of rapid corrosion, and you'll also need to use it. tie-belt with a ratchet mechanism or high-quality nylon slings for fixing the transom to the cylinders.
Don't forget to use sealants. A silicone sealant for aquariums or special polyurethane compounds (such as Sikaflex) will help protect the sticker and fastener holes from moisture penetration. Use yacht lacquer or epoxy to treat wooden surfaces of the transom.
- 🔧 A drill or screwdriver with a set drilled.
- 🔧 The keys are wrenched and capped (sizes depend on the fastener).
- 🔧 Waterproof sealant and degreaser.
- 🔧 Slings or carbine belts.
- 🔹 Marker and roulette for marking.
Use grovers under each nut, which will prevent the fastener from unscrewing spontaneously from vibrating the motor while driving.
Step-by-step installation instructions
The installation process begins with marking. The center of the transom and the attachment of the engine rods must be determined. The distance from the lower unit to the cylinders must be sufficient to exclude the screw from contact with PVC during rolling or excitement.
Next, you'll have to prepare the transom board. If it's removable, make sure that the belts that attach it to the cylinders are evenly stretched. The transmutation will cause uneven loading and can cause it to come off. When you attach the motor, use a regular rod, but you can add a safety rope for reliability.
☑️ Pre-launch checks
An important step is to lay electrical cables; the wires from the battery to the motor must be protected from rubbing and water ingress; use corrugated hoses or cable channels; all connections must be carefully insulated by shrinkage.
⚠️ Attention: Do not let the wires sag through the boat. When moving, they can catch the screw, which will short circuit and damage the insulation.
After installation, check the engine on land (short-term, in a container with water) to make sure the correct direction of rotation and the absence of extraneous noise.
Comparison of motor fixation methods
There are several ways to anchor the engine to the transom, each with its pros and cons, depending on the design of the boat and the operating conditions. Below is a comparative table of the main methods.
| Mounting method | Reliability | Difficulty of installation | Structure weight | Note |
|---|---|---|---|---|
| Staff scab. | Medium | Low. | Minimum | Requires a perfectly flat edge of the transom |
| Flying belts | High. | Medium | Low. | Universally, but takes time to install |
| Bolt connection | Maximum | High. | Medium. | Requires drilling of a transom or plate |
| Quick-removal brackets | High. | Low. | Medium. | Convenient for frequent engine change |
For most anglers, the best option is to combine a regular rod with additional belt insurance, which provides a balance between assembly speed and safety. Bolt connection It is more often used on boats with rigidly glued transverses, where the motor is planned to be removed rarely.
Nuances of the use of quick-removal brackets
Quick-removal brackets allow you to remove the motor in seconds, but they add extra height to the transom. Make sure that when folded, the brackets do not interfere with the packing of the boat into the bag.
Security and Typical Errors
Water safety is priority number one. The most common mistake is to make a safe water. weight-assessment The electric motor itself is light, but when combined with the battery and the lower unit, it creates a significant lever of pressure on the transom, and ignoring that fact leads to the boat tipping backwards.
The second mistake is saving on the fastener. Rusty bolts can burst at the most inopportune moment. Always use stainless steel fasteners of AISI 304 or AISI 316. It is also dangerous to attach the battery simply to the bottom of the boat: when hit by a wave, it can shift, damage the cylinder or close the terminals.
The third problem is the wrong depth of diving of the lower unit, and if the screw is too high, it will capture air (cavitation), which will reduce traction and can burn the motor winding, and if it is too low, water resistance and the risk of hitting the bottom will increase.
- ❌ Use of rusty or aluminum bolts.
- ❌ The engine is mounted on only one screw of the rod.
- ❌ Placement of the battery without fixation in a special box.
- ❌ Ignoring the belt tension check before each exit.
⚠️ Attention: Before each outing, be sure to check the puff of the rod. The vibration of the motor has the property of weakening even tight connections in the first 10 minutes of operation.
Maintenance and maintenance of the anchorage
After each operation, especially in salt water, you need to wash all the metal parts with fresh water, and the salt aggressively affects the metal, even stainless. Strubsins. and bolts should be periodically lubricated with silicone lubrication to prevent acidification.
Regularly inspect the squirrel board. The tree has the ability to absorb moisture through microcracks in the varnish. If you notice bloating or blackening, immediately remove the board, dry and update the protective coating. A raw squirrel is a risk of losing the motor.
Check the integrity of the wire insulation. Ultraviolet and mechanical damage can disrupt the insulation layer, leading to current leakage and battery discharge. Maintaining the system It extends the life of both the engine and the boat.
Regular maintenance of fasteners and protection against corrosion is a guarantee that your motor will not be at the bottom of the reservoir.
Can I use an electric motor on a boat without a transom?
It's not recommended to use a transom-free motor. There are pendants that are attached to the boat, but they disrupt the boat's balance and are less reliable. Tran is a must-have for safe operation.
How long should a PVC boat be lower unit?
For inflatable boats, 60-70 cm (short leg) of lower unit is usually sufficient. Longer shafts are designed for boats with a high side or rigid hull.
Do I need to remove the engine when storing the boat?
Yes, during long-term storage (winter) the motor and battery are necessarily removed. transom is also desirable to disconnect to relieve the voltage from the cylinders and allow them to dry evenly.
What to do if the squirt slides on the transucin?
If the rod slips, the surface of the transucin is too smooth or contaminated, wipe the mounting site with a degreaser, or, in extreme cases, stick a piece of rubber or abrasive tape on the inside of the rod sponges to improve the grip.
Does the weight of the motor affect the stability of the boat?
Yes, a heavy motor on a high transom raises the center of gravity, which can reduce stability. It's important to distribute the weight: the battery, as the heaviest element, is better placed on the bottom of the bow or in the center, rather than on the stern with the motor.
