Curtis There are lots of spots on a C&C 30 MKI where the sender will work fine, forward of the keel is definitely the preferred location as you have been told...inside mount works good but you will lose some range...I get 200 feet max which is just fine for my purposes but if thru hull mounted I expect the range would double... planting the transducer as close as possible to a cleaned (acetone washed) surface on the inside in a nice air free glob of GE silicone (100%) has worked fine for several years on Alianna... a bigger problem may be the wire run to the display head...I like that wire to be hidden as much as possible

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. Have a greay christmes.
