|INSURANCE ADJUSTERS WITH 'FOCUS'|
Hull identification serial numbers (HIN’s) should on all vessels built after June 1998 appear in the international ISO format with fourteen characters. The prefix should be the country code followed by the MIC (Manufacturers code) – three letters. This is followed by the production model and serial number followed by the month of production and year of production or model year.
This is set out as follows in this example:
GB (country code) – MPP (Manufacturers Code), 1A (Model)1234 (serial no.) F (month of build), 001 (year of manufacture or model year).
This ‘HIN’ should always appear on the transom permanently moulded or etched into the hull and occasionally on a permanently affixed plate. This is in the majority of cases to the starboard side of the transom.
Older hull identification serial numbers often have less characters and are presented in different formats. For example, Fairline Boats used a five or six character number or ‘yard’ number. Other larger manufacturers each had their own system and it is difficult to summarise every number configuration used.
Some speedboat manufacturers used a combination of model, serial number and year in their serial numbers (for example Fletcher used a simple model/serial number/year format on many models). This was presented on a plate on the dashboard.
Personal Water Craft
All personal Water Craft utilise the standardised Hull identification numbering format used by US boat manufacturers and which is almost identical to the ISO standard. The ‘HIN’ is found on the aft section of every PWC on a plate and the inboard engines also carry a serial number stamped into the engine block or marked on a plate. In addition many PWC’s are fitted with ‘Datatag’ which carries the principle identification data. This information is also held by Datatag in their database (contact Datatag on tel: 01932 358000).
There have been many outboard manufacturers over the years most of whom still survive though other older names such as Archimedes, Crescent, Chrysler (now Force) Seagull, Terhi etc have disappeared. In our Threestokes guide you will find contact details for most of the importers and you can verify serial numbers through them. Older engine information is still in our Threestokes Guide database and is available on application.
In almost every case the serial number plate will be affixed to the engine swivel bracket either on a riveted plate or sticker and is obviously marked with the model and serial number code.
Here is a brief summary on some outboards:
Example: 709HA - 1234
With nearly all inboard engines there are at least two numbers of importance. These are the engine serial number and the gearbox serial number. In outdrive installations you also need to concern yourself with the outdrive serial number and the transom shield number.
Serial numbers are always marked on inboard engines either on a riveted plate somewhere on the block and sometimes by being stamped into the engine block. These numbers often appear also on stickers placed on the head or intake housing so that they are conveniently accessible.
