Re: Need help with installing Tranducer on Aluminum Bass Boat
The 383c came with a little transducer mounting template in the installation instructions. If you have the paperwork it's in there, and it also tells you how/where to mount the xducer on both fg and aluminum hulls. If you don't have the paperwork and can wait, let me know and I can send you a photocopy. Check Humminbird's site as well. May be in there. Oh, and you'll love the 383c, great unit for the $$$.
