want to place in hull sensor in aft section of keel, any problems with this location?

Forward of the keel, as close to the centerline as possible is preferable.

Nice to know what lies ahead and now what you just hit. Also, the transducer sends out a cone shaped signal which bounces back from the bottom and if you are close the keel, this might have an undesireable effect.
