I understand from the CPT-100DVS installation manual that a 4mtr transducer extension cable is available - I am looking for the part number of this cable to ensure I purchase the correct one.

I would also like to know the required [censored] diameter to pass the transducer cable through the transom, I could not find it specified in the installation instructions.

Steve.

Welcome to the Raymarine Forum Steve,

The correct part number for the 4m extension cable designed for use with any of the transducers found here is A80273.

Excellent, Thanks!

You're welcome.
