Reinstatement of the engine identification number is not just a technical procedure, but a legal necessity for every owner of a small motorized boat. VIN code. Or factory labeling makes it impossible to register your craft with a GIMS, which automatically makes your boat illegal, and situations where you need to refill the number often occur: corrosion has eaten the metal, the plate has been lost during repair, or the engine has been purchased without documents as "contract".
The labeling process requires not only a specific tool, but also strict compliance with the regulations established by the supervisory authorities, errors in the location of symbols, their depth or font can lead to refusal of registration and the need to repeat an expensive procedure. Outboard Motors Tohatsu, Yamaha or Mercury have their own factory-branding features that you should consider when restoring. In this article, we will discuss all the nuances of self-labeling and official engine markings.
It is important to understand that self-stuffing of the number without prior approval and subsequent examination by a forensic expert has no legal force. Arbitrary rule This can be seen as an attempt to hide the stolen unit, so the first step should always be to diagnose the status of the marking site and contact an accredited laboratory or directly to the inspectorate for a prescription.
Why you need labeling and where to look for a factory number
The engine identification number is its unique passport, which allows you to track the history of ownership, model and year of release. GIME (Small-sized State Inspectorate) a readable number is a prerequisite for a boat's registration, without which you cannot get a boat's ticket and legally go out with the engine, and without marking, it equates to not having the engine itself as a legal node.
Manufacturers place information differently, and it can take time to find it, especially if the engine has already been in use, most often on the lower unit hub, on the mount bracket or on the cylinder block near the spark plug. Yamaha and Honda Often a metal sticker or plastic tag is used, which is destroyed over time by salt water and ultraviolet light.
If the factory sticker with the engine number is not readable, but the number itself is stamped on the metal is saved, the GIMS inspector can go to meet and register the engine according to the metal marking, but this is decided individually on the spot.
In some cases, especially on older Soviet or Chinese engines, the number can be painted, which inevitably wears off, and the owner has to face the restoration procedure. Forensic expertise In such cases, it helps to determine whether the number has been changed or simply destroyed by time, and if the examination shows no trace of interruption, you will be given a certificate allowing you to fill a new number.
Legal aspects and the procedure for restoration
The procedure for restoring the marking is strictly regulated. You can't just take a corer and knock out any numbers to your taste. You first need to write a statement to the GIMS about the absence of an identification number. The inspector makes an inspection report, fixing the fact that the marking is not readable. examination.
The forensic expert checks the engine for theft and design changes, and if everything is clean, a report is issued with permission to apply the new marking, the document specifies the place where the number is to be typed and its format, and only after this document, you can start the mechanical part of the work, trying to fill the number before obtaining permission can be considered as damage to physical evidence.
⚠️ Warning: It is illegal to apply a number without an expert laboratory certificate or a GIMS order, and if tested on water, the motor will be seized until the circumstances are clarified and the owner will be fined.
Once you have been authorized, you go to a specialized workshop or, if you have access and equipment, you do the work yourself (if the regional regulations permit), then you go back to the GIMS to check the number with the certificate, and then you enter the boat's ticket, and the whole process can take from a few days to a month, depending on the workload of the laboratories.
Necessary tools and surface preparation
A standard hammer and nail are not suitable because they will give ripped edges and uneven depths that will immediately catch the eye of the expert. pneumatic marker Or special cores with hard-alloy tips, and electric engraving machines with diamond cutters are also used to pre-prepare the site.
Surface preparation is a critical step: the application site must be cleaned to pure metal, defatted and, if necessary, leveled. If there are deep corrosive ulcers on the surface, they are carefully cleaned, trying not to reduce the thickness of the metal below acceptable values. Sometimes you need to cook a special plate if the home site is completely rotted, but this requires separate approval.
You will need to work:
- 🛠️ Pneumatic or electric marking tool with a set of fonts.
- 📏 Templates of height and inclination of symbols (usually height 7-10 mm).
- 🧼 Degreasing and rags to clean the surface.
- 🔨 Kerners and hammer (if hand-stuffed is used).
- 🎨 Anti-corrosion coating to protect fresh metal after stuffing.
☑️ Preparation for marking
It's important to find the right typeface. Factories usually use standard sans-serif fonts to make the numbers easy to read and not distort. The depth of the knockout also matters: too shallow will rust quickly and become unreadable, too deep can weaken the structure or be regarded as an intervention. Optimal depth for aluminum alloys. The outboard motors are 0.5-0.8 mm.
Technology of applying the number: step-by-step instructions
The process of applying the number is divided into several stages. First, you mark the center of the site. Using a template, you plot the location of the first and last digits to evenly distribute the entire number over the available area. Then, with light core strokes, you map out the centers of future symbols, so that when you stuff them, the characters don't "go away" to the side.
Direct padding is done by moving forwards. When using a pneumomarker, the needle automatically makes the right number of strokes to form a symbol. When manually stuffing, the punches must be of the same strength. It is important not to oil the metal during operation, because this will make it difficult to control the quality of the edges of the symbols. Once the padding is completed, the surface is cleaned again.
| Parameter | Requirement | Comments |
|---|---|---|
| Height of symbols | 7 - 10 mm | Standard for outboard motors |
| Depth. | 0.5 to 0.8 mm | Depends on the hardness of the alloy |
| font | Straight, sans serifs. | For better readability |
| Distance | 1-2 mm between the numbers | Don't merge symbols. |
What do I do if my hand shakes?
If the symbol is curved or double when stuffing, do not try to re-run it or smear it. This will immediately be visible to the expert, in which case you need to shift the marking pad (if space allows) and start stuffing again, or agree with the expert on the possibility of using an alternative seat on the engine.
Once the plate is full, it needs to be protected from corrosion, the fresh metal on the aluminum alloy is oxidized instantly, and a special transparent varnish or anti-corrosion lubricant is used that does not hide the topography of the numbers. Paint You can't have the number, it has to be contrast and readable, and often chemical blackening is used to improve visibility.
Typical errors and ways to fix them
One of the most common mistakes is choosing the wrong place: owners often stuff a room where the hammer is convenient, rather than where the examination certificate indicates, which leads to the inspector simply not finding the marking or finding it invalid. Always check the document, which schematically indicates the place of application.
Another mistake is to use too large a font or "disobedience" in the size of the numbers. If the engine number is long and the space is limited, you need to reduce the intersignature spacing, not the height, while maintaining the proportions. The uneven depth is also striking: numbers, stamped with different strengths, create the effect of "dance" text, which causes suspicion among inspectors.
⚠️ Warning: Never use thick graphite lubricants or solidol to protect your room, they clog digits, making the number unreadable without cleaning, which is a violation of the rules of use of markings.
If the number was stuffed with errors, it's extremely difficult to fix it. You can't clean and stuff it over, you can leave a trail of interference. The only way out is to move the pad and stuff a new number with a new permit, or to prove in court that the technical defect is not an attempt to hide the origin of the engine. It is better to spend more time preparing a stencil than redoing the work.
How to Protect Your Labels from Corrosion in the Future
Once the engine is successfully registered and returned to water, the main task is to keep the room legible. Aggressive marine environment, sand and stones quickly destroy unprotected metal. It is recommended to regularly (once a season) clean the marking area with a brush and cover with a thin layer of transparent anticorcory.
Some owners install protective plastic casings or close the site with a layer of transparent high adhesion varnish, the main thing is not to block access to the numbers with completely opaque materials, periodic visual monitoring of the condition of the room will help to notice the corrosion that is beginning and take measures without making it completely unreadable.
Regular preventive cleaning and lubrication of the marking area after each season prolongs the life of the room and eliminates problems with annual re-registration or water checks.
Compliance with these simple rules will allow you to avoid problems with the law and enjoy fishing or cruising on the water. Remember that marking is primarily a guarantee of your legality and safety, confirmation that your engine is not listed in theft and passed all the necessary checks.
Frequently Asked Questions (FAQ)
Can I get a number on the engine without examination?
No, self-stuffing without an examination or GIMS prescription is not legally valid and can be regarded as an illegal change in marking.
How much does the number restoration procedure cost?
The cost consists of state duties, services of an expert laboratory (from 3 to 10 thousand rubles depending on the region) and services of a stuffing workshop (about 1-2 thousand rubles).
What if the engine number is completely rotten?
If the marking site is destroyed by corrosion, the expert may allow the number to be applied to another, free part of the engine (for example, on a mirror surface or bracket), indicating this in the certificate.
Do I need to register a homemade outboard motor?
Yes, any motors over 5 hp (or propelling a vessel if a vessel requires registration) are subject to accounting. For homemade motors, the procedure is more complicated and requires proof of safety of design.
