If you need a transducer, speed paddlewheel, or power cable, your best bet is probably to ask your local marine electronics dealer to contact one of the following two distributors:
If you are in the USA or Canada: contact Gemeco Marine Accessories at sales@gemeco.com or phone (803) 693-0777.
Outside North America: contact Airmar-EMEA at sales@airmar-emea.com or phone +33 223 520 648.
If you’re looking for something else, such as a coupler for an Impulse loran, or a GPS or compass module for the 4040, I’m afraid I can’t help you, except to suggest eBay.
