Request a quote for this model.

Free of charge — we forward your request to qualified suppliers for Wärtsilä equipment from our network of over 114,000 maritime companies.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we usually come back with prices; without them we have to ask first, which costs a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — send it as a reply to our confirmation e-mail.

Your contact details are not published. No account required.
