Hey tahnks david, this helps alot. I have been looking aroind the internet this morning and think I can do it. I have 2 thru-hull transduciers in thethe location just foward of the keel in the foward bilge in the bathroom. So maybe I can go just foward of the bulkhead in the foward birth and find a suitable spot. Thanks again for your help.
