Many can not imagine modern hunting or fishing without such a vehicle as a motor boat. Most often, these vehicles are equipped with an outboard engine. Their power can vary from 2.5 to 50 liters. from. and even more. To improve its performance, many craftsmen make a hydraulic wing on the outboard motor with their own hands. How to create such a device, what are its main advantages and disadvantages, you should find out before starting work.
general characteristics
Outboard motor (PLM) has been used by mankind for a long time. Hydro wings for such devices could be found in almost all parts of our planet where there are water bodies. The most widespread anti-cavitation devices for PLM were in the Indian Ocean, Baltic, Europe, etc.
Many novice fishermen ask why they need a hydraulic wing for an outboard motor. Do-it-yourself fishing lovers never get tired with their own hands to improve inflatable boats. Indeed, there are often situations when a boat with the same parameters on a pond much faster goes to planing, while maintaining good controllability. At this moment, the heads of many fishermen visit the thoughts of improving their swimming equipment.
One of the most popular areas for improving the operational characteristics of a boat is installation on a hydraulic wing motor.
Hydro wing functions
A certain type of tuning is the installed hydraulic wing on the outboard motor with your own hands. The purpose of this additional element is primarily due to the acceleration of the transition to planing (about 15%). Moreover, in this mode, the movement becomes smooth, without jerking.
Some fishermen noticed that with increasing speed and movement in short waves, the engine makes a different sound, as if it were not immersed in water. The hydraulic wing is able to eliminate air from entering the screw. In this case, there will be no sharp decrease or increase in the speed of movement in grab.
With a hydro wing, the bow of the boat will not bulge so much. By increasing the area of the anti-cavitation plate, the stability of the course increases. Also, positive changes will be felt when making a turn. The radius of the drift will be smaller. The turn will be "sporty." In addition, the use of a hydraulic wing reduces the consumption of a combustible mixture.
Varieties
All hydro wings are divided into two types. The first devices consist of a solid plate. These are single wings. Standard varieties consist of two separate plates.
In addition to structural features, such devices are distinguished by the power of the engine for which such a device is added. The first group includes hydro wings for engines up to 25 liters. from. The following are designs for PLM 25-30 liters. from. The following category is reserved for hydraulic wings of engines of 30-50 liters. from. There are devices that are designed for more powerful PLMs.
Some fishing enthusiasts claim that it makes no sense to install the presented type of tuning on engines less than 6 liters. from. However, there are reviews of professionals who make it clear that a hydrofoil on a 2.5 outboard engine with their own hands can be mounted. In this case, the performance of the vehicle also increases.
For trolling, a special type of hydraulic wings was developed. This design has the shape of a scapula. It folds towards the screw down. This principle allows you to create a higher level of resistance, reduce the speed of the vessel.
Hydro wing disadvantages
Deciding to make a hydraulic wing on a boat motor (PLM) with one's own hands , it is necessary to consider a number of shortcomings of the equipment presented. They are inherent in almost all varieties of designs.
First of all, it should be noted a decrease in speed. Moreover, such a drop is observed in the range from 5 to 7 km / h.
Also, in the case of movement on water with a lot of algae, the vegetation gets tangled up on the motor. To clean the engine with a hydraulic wing will require much more time and effort. This problem is relevant for those fishermen who often have to go in shallow water. The hydraulic wing reduces access to the propeller if necessary to clean.
In some cases, installing a hydraulic wing does not provide a significant improvement. This is especially true for motors with low or very high power.
The choice of the type of hydro wing
First of all, you should decide whether to install a purchased or home-made variety of hydraulic wings. If there is enough time, as well as the desire to do such work, you can make the design yourself. But most often, novice masters get a ready-made kit for installation.
The choice of the required model is made in accordance with the engine power. Some fishermen claim that by installing a hydraulic wing on a 5 liter outboard motor. from. do it yourself, you can’t achieve the desired improvement. However, wanting to quickly put the vehicle on glide, this design is used even for the most low-powered engines.
For medium and high power engines, it is preferable to install single wings. Standard varieties are designed for motors less than 25 liters. from.
The material from which the structure is created is most often plastic. It is better if the hydro wing has longitudinal grooves. This form allows you to stabilize the water flow. For low-power engines, the trailer is well suited. It is a segment located perpendicular to the main plane.
Materials and equipment
To create a hydraulic wing on a boat engine with your own hands , you need to prepare the necessary materials and tools. The home master usually has them in the arsenal.
Of the tools required grinder, bolts (6 mm), primer, paint. The material for creating such a design can be a duralumin plate, as well as other similar materials.
Primer and paint are applied after the shape of the wing is created. This protects the device from destruction during operation.
Making a hydro wing
Some fishermen prefer to create a hydraulic wing for the outboard motor with their own hands . This allows you to save money on the family budget, as well as spend your free time interesting and productive.
Among the existing technologies of this process, the approach that involves the creation of such a structure from a plastic or metal shovel is very popular. Such a material is known for good strength and optimal dimensions. To do this, use a grinder.
First, the part that adjoins the handle of the shovel is cut off, and a central groove is also made. This results in an opening for the motor foot. Next, you need to drill holes for mounting the structure to the anti-cavitation plate. To make installation simple, you need to make all measurements as accurate as possible. This is especially true of the screw part of the engine, to which the wing will fit.
All sharp corners are rounded. The side of the leg attachment needs to be cut at an angle of 20-30º. If the shovel was metal, it can be straightened with a hammer. Plastic needs to be cut.
Installation
Considering how to make a hydraulic wing on a boat engine with your own hands , you need to pay attention to the installation of the structure. First, degrease all surfaces and parts. For this, non-woven material and an alcohol solution are used.
After the surfaces have dried, rubber pads are glued. It is best if the ambient temperature is not lower than 18º, as well as in clear weather. The end result will be better.
Then, first, the upper and then the lower parts are attached to the anti-cavitation plate. For this, for standard wings, 2 screws are used on each side. They are tightened very tightly. All structural elements must not stagger.
Some recommendations
The hydraulic wing on the outboard engine is done by the owners of the vehicles, which put it on its hind legs when moving. An additional design will allow the nose not to bulge. Landing of the vessel will be leveled.
Also, the wing helps to quickly reach the glide. This contributes to fuel economy. You should also consider the angle of attack. For fast boats and high engine power, the hydraulic wing allows you to increase this figure.
Having considered how to make a hydrofoil on a boat engine with your own hands , you can improve some of the characteristics of your boat . Almost anyone, even a novice master, can do this procedure.
