gp1850df transducer help


New member
Hello, I have a furuno gp1850df and a furuno 520t-hpd with a ten pin connector.
I would like to use it at 1000 watts. How can I do this? Thank you in advance.

You will need to open up the 1850 and change an internal jumper. The instructions are on pages 3-10/11/12 of the installation manual. If you don't have the manual you can download it from this website. Just type in GP-1850DF up in the Quick Search window and the Installation manual should be the fifth item down.
