Title: Installation Issue
Review: It is not stated in the description of the Garmin 90 but you have to drill a 1-1/8" hole in the top of the console in order to pass the transducer cable through to the unit. The large size of the connector also made it impossible for me to pull it through the under floor access tube from the transom to the center console. Take a look at the Humminbird PiranhaMax 160 as it only requires a 5/8" hole.
