Are spare parts readily available for my equipment?

Yes. Nautical Structures suggests carrying a spare parts kit for your equipment - especially if you will not be near a port. Please keep in mind that parts vary depending on the year, make and model of your equipment.

Below is a general spare parts kit:

Please provide your serial number and model so we may provide the correct parts for you.

Where can I find the serial number to my equipment?

The serial number is usually stamped into the mast and can be viewed when the boom is in the up position.

The serial number on a Passerelle or Gangway is located on the Manifold Plate.

The serial number on a Transom Lift is found on the Pump Tray/Plate.

What if I cannot find my serial number?

If you cannot find your serial number or it is no longer legible, you should provide the make/model of your vessel as well as the vessel hull number for identification purposes.

What type of hydraulic oil do I use for my system?

It is recommended you use a filtered AW-68 for any products build before 2009. Products built from 2010 to present use Biodegradable Hydraulic Fluid. You can purchase this from Nautical Structures.
