We recently acquired several Smartcraft transducers from a boatbuilder downsizing excess inventory. We have created complete tri-ducer kits by taking an 881931 transom mount depth transducer and combined it with a 859223 add-on speed/temp sensor, which clips onto the back of the depth transducer.

If you have found this listing, chances are you're replacing your aging transducer and it would benefit you to replace both the depth and speed/temp sensors. Also included is a new installation kit, instructions, and 2x connector housings with wiring diagrams for both connections.

Please note: There are two different wire color combinations for the speed/temp sensor - this is due to Airmar changing the wire colors mid-production. We have included the proper diagram for both iterations - there is no difference in functionality between them, the colors are simply different on the 2 versions. Additionally, there are a couple other harnesses that include fuses and such for these smartcraft transducers. These should already be present on your boat but please take note of what's included and what is not - some of these ancillary harnesses are not included.
