Technical & Product FAQs

11. How can I identify my marine engine model and serial number?

Every marine engine has a model plate (or nameplate) attached to the engine block or valve cover.
It lists key information such as model designation (e.g., 4JH80, D6-330), serial number, and rated power.
If your plate is damaged or missing, send us a clear photo of the engine — our technical team can help you confirm the correct model and matching parts.

12. What is the difference between EXW, CIF, and DAP shipping terms?

These are Incoterms 2020 defining shipping responsibilities:

  • EXW (Ex Works): Buyer handles pickup and all shipping costs from our facility.
  • CIF (Cost, Insurance & Freight): Seawave Marine covers freight and insurance up to the destination port.
  • DAP (Delivered at Place): We deliver directly to your address or yard, ready for unloading.
    We help each customer select the most efficient and cost-effective option.

Optional accessories such as gearboxes, shafts, or mounts can be added upon request.
