Replacing watercraft engines using the e-services

Check that you have a deed of transfer (External link) identifying the engine as well as the details of the seller and the buyer.  

If you have bought a new engine, check that you have its declaration of conformity. You can usually find the declaration of conformity in between the user’s manual. 

Note, if you change CE-marked boats technical data, you need to present a new declaration of conformity with documents.

Scan or photograph the documents before you start filling in the notification.

You can have a look at the registration form in advance to familiarise yourself with the required information (External link). All information marked with an asterisk (*) on this form is also mandatory when you submit the notification using the e-services. Some of the data may have been filled in before in your watercraft's information. In case of an old boat, however, the data may be very deficient. 

Identification is required to use the service. You must be aged 15 or over.

Select on the list the watercraft whose engine you wish replace. Select the Change the technical specifications of a watercraft service. 

Fill in the missing technical specifications of a watercraft.  

On the Check engine data page, you should first remove the current engine of the watercraft before adding the new one.  

You should start by searching for the engine by entering its identification number and make.  

Check that the serial number format is correct. Different makes have different serial number formats. Having the correct engine serial number is important to make sure that the system can find the information if the engine has already been registered or if the manufacturer has submitted an advance notification. If the system finds the engine, you need not enter all of its data manually.

Once you have added the engine specifications, you can upload the engine's bill of sale or deed of transfer and any declaration of conformity to the system. 

On the last page you will receive a message stating that your notification is being processed. On this page, you can print a receipt. The replacement is free of charge. 

If you indicated that you intend to deliver some of the attachments by mail, print out a covering letter on the confirmation page. When you attach the covering letter to the mailed documents, they can be linked to the right form and the registration can be processed faster. Please note that if you have indicated your intention to send some of the attachments by mail, the processing of your registration will not start before all the required attachments have been received.
