We have a 1987 3207 and I want to put a Humminbird 1158 up on the flybridge. I don't really want to mount the transducer on the transom and was thinking of using one the two locations mid-ships that there are old thru hull transducers mounted now. Has anyone else done something like this? Humminbird makes an angled thru hull transducer. Would this work better? Is the post next to the helm station the chase for getting wiring, etc up to the bridge? Thanks.
