Miscommunication. They probably meant that if you try to install your SI ducer in the bilge, SI will not work. If SI is now working at slow speeds as it is meant to, then leave your SI ducer where it is, and then, as mentioned above, add a separate shoot through with “y” cable. It is more common to mount the SI ducer on the jackplate though.Last edited by catdude28 on November 11th, 2015, 1:53 pm, edited 1 time in total.
