Motorcycle of water expanses. Do-it-yourself jet ski - drawings for a homemade jet ski Make a jet ski with your own hands

Prepare a sleigh in the summer, and... a jet ski in the winter - why not? Alas, not everyone can afford to buy a jet ski, but since you can’t buy it, let’s try to assemble it yourself. This will not take as much time and effort as it might seem.

Let us renounce the use in advance, even though industrial models are usually made on this basis, the fuel consumption is too high - water travel on such a unit is very expensive. It is best to use a boat motor - there is cost savings and a sharp increase in functionality: whether on a long journey, even for water skiing, and the speed promises to be exciting. All you need is to select the screws at the best speed for the selected mode.

It’s as easy as shelling pears to assemble a jet ski using a system – two floats, a seat, a speed control lever, a steering wheel, and a cable control transmission. Please note that a good float is always made of polystyrene foam and externally lined with fiberglass and epoxy glue. 5-6 layers of fabric are placed on the bottom of such floats, and no more than three on the sides, this is enough. Special wooden frames located in the places where the seat and the catamaran are attached distribute the weight of the riders and the structure.

You can experiment a little, for example, equip your creation with a third float or work a little on the design - many “garage” developers produce very nice water bikes, moreover, high-quality ones.

3 float jet ski

The floats are made of polystyrene foam, power fastening elements, and root ribs made of plywood. In the role cross beams the most ordinary performers cross-country skiing– simple, durable, good load absorption. Here, of course, at your discretion, you can replace them with seamless ones steel pipes, at least for duralumin ones.

Classic jet ski

It is not necessary to use floats; you can also make a model that will look terribly like expensive Yamahas - after all, they are more pleasant to ride, right? The structure itself is a frame-stringer frame, covered with 3 mm plywood, then covered with fiberglass.

Lever-cable control system, just like the kit for remote control outboard boat engine. However, it uses a motorcycle handlebar, and the rotating motorcycle handle serves as the throttle lever.

Such a water horse can be transported on a rack on the roof of a car - its weight and dimensions allow you to save on an additional trailer.

Boat type jet ski

This creation can be used, for example, for fishing or swimming, or traveling around the water area. The wide hull will prevent the jet ski from turning over even when an adult climbs on it. Fairly good stability will help you stay afloat if a boat or boat suddenly floats by. On this transport, diverging waves are not at all scary.

What’s remarkable is that stability doesn’t really slow down speed. The hull is wide, but some jet skis of this type can be put on plane using motors from 8 horsepower - for one person, more powerful motors (Vikhr) - for two, and even a water skier on the back. Impressive, isn't it?

But there is a drawback here - you will have to fork out money for a trailer. However, loading/unloading a homemade jet ski will require the strength of only two people.

Select a drawing, purchase materials and try it out - summer is still so far away, but time will fly by when creating a water bike with your own hands. Wishing you a fast and safe ride.

Homemade jet ski - is it possible?

At first glance, it seems that only a madman would dare to make a homemade jet ski. The idea is quite feasible if you have enough experience and good ingenuity.

Making a jet ski by hand takes a little time and effort. To significantly save on fuel, it is better not to use a water cannon. If you take an ordinary outboard motor, you can expand the functionality of the unit and provide it with good speed. Correctly selected screws for the speed are already half the success.

What do you need to create a jet ski with your own hands?

The materials needed to create a jet ski depend on the type of design.

2 float jet ski

To assemble a jet ski from scrap material, and even with your own hands, you need. This bike is easier to assemble; it is designed on the principle of a catamaran. The design includes a seat, several floats, a lever, and controls. A float made from foam plastic is always of high quality; preference should be given to this material. You need to cover it with fiberglass with epoxy glue. It is better to lay five layers inside the floats durable fabric, and three will be enough on the sides. How are jet skis made correctly to optimally distribute the weight of vacationers? It is necessary to place wooden frames in the places where the seat is attached.

3 float bike

To make floats you will need polystyrene foam, plywood ribs and a power fastener. Ski beams can become cross beams. Regular skis are suitable for this, as they provide load distribution. In addition to skis, steel pipes can be used.

If you want to return to the classics, you should understand how jet skis of this type are assembled. This model is made without floats, but is not inferior in functionality. The structure is made in the form of a frame covered with plywood. To control, you can take the steering wheel from a motorcycle.

Boat type bike

Transport can be used for swimming or fishing. Diving enthusiasts can climb onto the hull without fear. Excellent stability will allow you to stay afloat even when a boat floats past. Reliability does not affect speed. You can use a powerful motor and put the unit on plane. This scheme will have one drawback - an expensive trailer.

A homemade jet ski may lose a little finished products according to several parameters: appearance and low speed. But, if you get down to business wisely and spend enough time, the jet ski will be powerful without overpaying for the brand. So, let's assemble a homemade scooter.

Frame

When making a jet ski with your own hands, the quality of the body is important. This is a stringer frame that is covered with plywood. You need to draw the future body on a sheet of plywood. For future frames, pine slats are prepared in advance. The plaza should be covered with polyethylene so that the frames can easily separate from it without damaging the surface. With nails small size slats are attached to the plywood. Later, you should cut out the gussets from the plywood and secure them with epoxy glue and screws. Separate the frame from the plaza and install the gussets on the other side of the frame. It is recommended to fill the resulting holes with foam plastic.

Transom board

Such a frame should be covered with plywood on all sides, and the motor mounting points should be covered with pine blocks. The frames that were prepared in advance must be secured to the board using small nails. You should take care of symmetry and carefully set the frames. The speed and stroke of a hand-made water scooter depends on symmetry.

Installation of stringers

They are fixed in the grooves of the frames using epoxy glue. When the resin has hardened, the structure is cleaned with a rasp and a plane. The ribs that protrude are brought together relative to the surface of the body.

Hull plating

For convenience, it is better to start from the bottom. You will need a board 4 mm thick. Ideally, the workpiece should be slightly larger, and the excess material is then removed. After this comes the covering of the remaining sections of the bottom, sides and deck with fairings.

Sheathing of remaining sections of the bottom, sides and deck with fairings

To cover a custom homemade jet ski, made by yourself, you need epoxy glue and screws with a special head called a “countersunk” head. It would be better if they were made of brass. The longitudinal steps must be attached to the rack body with glue and screws. To round the cheekbones, you need putty.

Covering the body with fiberglass

The bottom of a homemade jet ski is covered in four layers. If you don’t have such fabric, any thick one will do. Once curing begins, a flap can be cut out and rubbed onto the surface. This trick will allow you to obtain a surface that does not require additional processing.

Payol

Assembled from screws and glue. It is sanded and impregnated with several layers of drying oil. Then coated with oil varnish.

seat

It is a box with a lid, covered with a layer of polystyrene foam and foam rubber. The top is covered with leather or leatherette.

Some secrets and usefulness:

To reduce fuel consumption when riding a homemade and original jet ski, it is necessary to replace the water jet system with a screw one. The speed will become a little slower, but it won't be noticeable.
Change the control system so that you don’t have to master transport all over again. You need to choose the scheme you like and adapt it for your comfort.
To create a cool jet ski with your own with my own hands, you will need to study the drawings. It is better to select a drawing in advance, decide on the model, and then purchase tools and materials for the future scooter.
Follow safety precautions carefully. The product will have to be registered, so it must be safe and meet standards.

After studying the diagrams and instructions, we can conclude that making a homemade water scooter with good parameters quite real. Patience will be rewarded when you get to ride your creation for the first time.

Jet ski is very good summer fun, you can use it to rush around the pond, take girls for rides, and have fun. Of course, a homemade jet ski is not, it does not have such capacity, but, on the other hand, it is more preferable for entertainment on the surface of the water.

Jet skis manufactured industrially They have a water jet-based propulsion system, this is done to ensure safety. However, a water jet has poor fuel consumption characteristics, especially at low speeds, so using an industrial jet ski for water travel is expensive.

Another thing is a homemade jet ski!

Having made a homemade jet ski, you can go on a wide variety of tours on it. And what? Quite a summer trip!
When making a jet ski with your own hands, you can use more economical option and equip a homemade jet ski with ordinary outboard motor. This approach will allow you to use a jet ski both for high-speed “breezy” trips, water skiing, and for long-distance water travel. It is enough just to change the propellers, selecting them for the optimal speed of a given operating mode of the outboard motor.

The most simple view homemade jet ski is the use of a two-float catamaran system. In fact, you only need to install the seat, steering wheel, engine speed control lever and control cable transmission.

The floats of the catamaran are made of polystyrene foam and then lined with fiberglass and epoxy. 5-6 layers of fabric are placed on the bottom of the floats; 3 layers are enough for the sides. In the places where the catamaran is attached to the seat of a homemade jet ski, additional wooden frames are installed, which distribute the weight of the structure and the riders.

One more interesting project homemade jet ski is a project of a 3-float jet ski made by yourself.

You can follow the link at the end of the article.

The design of a 3-float jet ski is simple; the floats are also made independently from polystyrene foam, plywood root ribs and power fastening elements. Ordinary cross-country skis were used as cross beams. They are quite durable and absorb the load well. However, if desired, they can be replaced with seamless steel or duralumin pipes.

Another design that is more familiar in appearance, this homemade jet ski is assembled on the basis of classical technology: it is a frame-stringer frame, covered with 3 mm thick plywood and then covered with fiberglass.

A few words about the control system. A lever-cable type control is used, the same as that included in the kit for remote control of an outboard engine on boats; the only difference in controlling a homemade jet ski is that a motorcycle steering wheel is used, and instead of a gas lever there is a motorcycle rotating handle.

The dimensions and weight of a homemade jet ski allow it to be transported on a rack located on the roof of any car. This means that there is no need to purchase an additional trailer to transport a homemade jet ski from the storage location to the reservoir.

The third type of homemade jet ski allows you to use it as a small fishing or swimming boat and for traveling around the water area. The wide body of a self-built jet ski does not allow it to tip over even when an adult climbs onto it from the side. This same excessive stability allows you not to worry about boats and motor boats passing nearby; the waves diverging from them will not be able to capsize your homemade jet ski.

Despite the rather wide hull, the built jet ski is very playful; with one person it can go on plane even with an eight-horsepower engine! And after installing a more powerful Whirlwind, this homemade jet ski easily went out into the air with two passengers and dragged a water skier along with it.

The only disadvantage of this design of the jet ski is that a trailer is required to tow it. But loading and unloading the jet ski can be done with just two people.

In general, it’s up to you to decide which one to build a gyrocycle with your own hands. Maybe, based on ready-made jet ski drawings, you will decide to build a self-designed jet ski and share your information with us.

Above the apparatus called “LANI” Alexander and Ivan Lipatnikov from the village of Vishkil Kotelnichsky district worked for about a month. Recently, a jet ski was tested on the Vyatka River.

The name "LANI" is an abbreviation made up of the names of brothers and father: Lipatnikov Alexander, Nikolai, Ivan

Everything is fine. “It runs fast,” 25-year-old Ivan noted, smiling, immediately after the run-in. - True, a lot depends on what kind of engine it is. We set it to 9.8 horsepower, it pulls well. We're thinking of trying for 30.

According to the brothers, they dreamed of their own jet ski for a long time, but could not afford it. It’s no joke, in the store such a unit costs two hundred thousand and more. In a word, they took it and assembled it themselves.

The homemade jet ski is made almost entirely from plywood. Plus, fiberglass was used inside and, of course, spare parts that were found in the garage.

It must be said that making equipment with your own hands is nothing new for the brothers. Often their father helps them with this. The craftsmen already have seven hand-built amphibians (ships on air cushion), six of which roam the expanses of different Russian regions: Arkhangelsk, Vladimir, Krasnoyarsk, Murmansk and other regions.

By the way, according to the eldest of the brothers, 33-year-old Alexander, their jet ski is in no way inferior to its factory counterparts, and in some respects it is superior.

There’s more adrenaline here,” the interlocutor shared. - An ordinary jet ski has good speed, you can make sharp turns on it, but it won’t be able to stand up like a candle, it won’t be able to rear, but ours can do it easily, since it’s more maneuverable.

In addition, the Lipatnikovs said, their device is significantly lighter: not 200 kilograms, like store-bought ones, but only 60. If others need a trailer, they put this one in the car trunk and went where they needed it.

The masters admitted that they have big plans: to build an impressive boat with a cabin for six people, so that they can travel along the river without fear of bad weather.
